(This is on a Mac by the way. It seems cp -r on a Mac is "historical" and should be replaced by cp -R).
I tried the following:
mkdir TryContext
cd TryContext
npx create-react-app my-app
cd my-app
and then I made an app that worked, and npm start was able to start the server and run it.
But then if I want to make a version 2 of this app, and started by cloning the folder first:
cd ..
cp -r my-app my-app-02
to copy everything to my-app-02, and cd into that folder and do npm start, it will error, saying
> my-app#0.1.0 start /Users/username/code/TryContext/my-app-02
> react-scripts start
internal/modules/cjs/loader.js:800
throw err;
^
Error: Cannot find module '../scripts/start'
I tried different ways, and tried npm rebuild and then npm start, and it worked. But I thought if you copy a directory "as is", then using it, npm start should start the server without needing to do anything? Why was that and what ways besides npm rebuild could fix it?
TL;RD: when you copy using cp -r it doesn't really preserve symlinks, it just copies the file contents instead. So npm start can't find necessary symlink in this particular case. One of the possible solutions is to use cp -a when coping, which preserves symlinks and avoids this issue.

I have installing react app using this command
$ npx create-react-app my-app
Then I got Error like this:
Error: EPERM: operation not permitted, mkdir 'C:\Users\Aniket'
command not found: create-react-app
I have seen some online resources they are saying I have to remove space from my Windows Username, isn't there any other way of make this work?
Make sure you've node>=8.10 and npm>=5.6 already installed
Try installing it globally first, using the command
npm install -g create-react-app
And then, you can create your app using the command,
npx create-react-app <Name of your app>
Hope this helps :)
Edit: Above solution might work but it's not recommended way of solving this issue. Please refer https://create-react-app.dev/docs/getting-started
I referred the solution given at bottom and some other posts to use below command:
npm config set cache "C:\Users\mycomputer~1name\AppData\Roaming\npm-cache" --global
The easiest way for me is:
mkdir C:\cache
npm config set cache "C:\\cache"
And then run the command again.
Go to c:/users open command prompt and run dir /x check shorter name you found with dir/x as shown in image and run npm config set cache "C:/Users/<shortname-you-found-with-dir/x>/AppData/Roaming/npm-cache" --global
In my case it's CYBERC~1.
this works fine in my case.
I am using Git Bash terminal on my Windows 10 machine. I have below versions of node and npm
$ node -v
v12.16.1
$ npm -v
6.13.4
However while running the command $ npx create-react-app my-app I am getting the below error
'create-react-app' is not recognized as an internal or external command,
operable program or batch file.
I have added the create-react-app location till npm in PATH variable and checked its present using the echo command.
Also I am able to run the above npx command in cmd but not in Git Bash. Is there anything different I have to do run it?
PATH : /c/Users/SAURABH/AppData/Roaming/npm
I am able to run the create-react-app by doing the below though:
C:/Users/SAURABH/AppData/Roaming/npm/create-react-app one-hello-world
Not sure why npx is not working
EDIT: I solved by adding the below to PATH
C:\Users\SAURABH\AppData\Roaming\npm\node_modules
But the above path has the create-react-app folder and not the batch file. It should point to some batch file right?
I have same issue on my mac, start using yarn create react-app my-app . This solution works for me.
You should try this command with cmd or PowerShell. it's a bug with GitBash.
I can solve this error with cmd.
I was new and want to learn ReactJS and I start to install a new empty folder with npx create-react-app . command. I have npm v.6.4.1. and when I try to execute the command, it gave me an error.

Install for create-react-app#latest failed with code 7
I already do the same command on Laravel empty project, but I still gives me the same error.
Can you tell me what's the main cause problem and how to fix this?
EDIT: I already run the terminal as administrator, but I receive another error:
npm ERR! code ENOLOCAL
npm ERR! Could not install from "2\AppData\Roaming\npm-cache\_npx\10552" as it does not contain a package.json file.
npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\LOGIVAR TY 2\AppData\Roaming\npm-cache\_logs\2019-01-23T04_18_56_036Z-debug.log
Install for create-react-app#latest failed with code 1
In my case the actual issue was due to the presence of a space in my windows user name folder. Which also appears to be the case here by looking at the first line of the stack trace,
Error: EPERM: operation not permitted, mkdir 'C:\Users\LOGIVAR'
Since there is no directory present named LOGIVAR its trying to run mkdir, for which its getting operation not permitted.
Following is how i fixed it thanks to citoreek, g8up & gijswijs
run npm config edit to edit your config, this will open up a text file in notepad or your configured editor,
then change cache path from
; cache=C:\Users\Gijs van Dam\AppData\Roaming\npm-cache
to
cache=C:\Users\GIJSVA~1\AppData\Roaming\npm-cache
Remember to remove the ; at the start,
next question would be how do we know to replace our user name with GIJSVA~1?
There are a couple of ways to target this,
Go to C:\Users open power Shell and execute following command
cmd /c dir /x
what this does is, list down all the directories in current directory along with their short names which aren't supposed to contain any spaces and normally are 6 characters or less in length. Copy that short name against your user name directory and use this in your cache path.
You will notice these short names only exist for directories either containing spaces or which are longer than 6 characters, for the rest of the directories their short names will be same as their directory name,
If you don't want to use above command, then simply remove all the spaces from your user name in your cache path, then take the first 6 characters of the user directory name and postfix it with ~1. You should also uppercase it, but it appears not to be making any difference.
After you are done with editing this file, save your changes then try again after closing any active power shell / bash process and reopening them.
First to install globally
npm install -g create-react-app
Create your new app
npx create-react-app your-app-name
this worked for me
Have you tried running this as admin?
add project name like this in your command:
npx create-react-app your-project-name
This is an issue with npx. Your computer name has a space in it. I'd recommend npm install -g create-react-app to get around the npx issue.
The above stated problem is due to the white space contained in the folder name. Best way is to make changes the config file.
Enter npm config edit to enter into your config file
Then change
; cache=C:\Users\Sinojia Zeel\AppData\Roaming\npm-cache
to
cache=C:\Users\SINOJI~1\AppData\Roaming\npm-cache
Don't forget to remove semi-colon from the front
The SINOJI~1 can be replaced with your folder name that contains white space.
Just take first 6 letters of your file name and in suffix add ~1(Capitalizing the file name is optional but often it is done)
Save the file and exit and re-run the npx create-react-app . command.
The below command worked for me:
npm install -g create-react-app
npx create-react-app project-name
If you are still facing this issue, after all of the above -
I had the same issue with the space in my name, I tried:
npm cache clear -f
npm cache verify
updated the cache path with the "~!"
And none of that worked for me, but then I ran:
npm -g install npm
npm init react-app my-app
... and it worked finally. Hope this helps someone out there
First install create-react-app
npm install create-react-app
then
npx create-react-app app-name
I ran into a similar issue while creating a React app from Linkedin Learning it had the command -
npx create-react-app my-website --use-npm
to create a new React application but didn't mention if it required any prerequisite.
So in order to run the above command, first install the create-react-app with
npm install -g create-react-app
I was also getting the same error:
Error: EPERM: operation not permitted, mkdir 'C:\Users\Username'
command not found: create-react-app
Then the below command worked for me:
npm install -g create-react-app
npx create-react-app project-name
Check your node version. If you are using like node v14 it might be the problem. In my case, since I switch between different versions with NVM, I than realized that I was using v14 rather than v16+.
To see your current node version, open your terminal and type:
node -v
I'm running a Windows 10 machine. I have tried to install node and git but whenever I try using git or npm it just return the user pointer back.
WindowsPC MINGW64 /c/Angular
$ git clone https://github.com/angular/quickstart my-app
Cloning into 'my-app'...
WindowsPC MINGW64 /c/Angular
that is what happen when i use git. it did not create the folder my-app
and if am using the cmd
C:\Users\Username>npm -v
C:\Users\Username>
Nothing seems to work
however if i try to check node-v it works fine.
C:\Users\Username>node -v
v6.10.0
C:\Users\Username>
so do any one what could be the cause of this?
Because I can't learn angular 2 because of this
As git clone didn't report any error it seems it was successful.
So just do cd my-app after the git clone and you should be inside your newly cloned repository.
and if you just
md my-proj
cd my-proj
git clone https://github.com/angular/quickstart.git
files are there ?
I tried to install generator-angularjs using Yo (Yoeman) without sudo:
npm install -g generator-angular
I get:
Error: EACCES, mkdir '/usr/lib/node_modules/generator-angular'
When I type in sudo yo, yo tells me that I should not use sudo (which is perfectly understandable).
I have a ~/node_modules directory - why doesn't yo install its packages there?
Generators are designed to be installed globally. Otherwise, you always have to install the generator you're about to use in each project, which is unnecessarily painful. Also, you don't get to see the lovely yo menu which lists you all the available generators (unless of course, you install them all locally):
Setting up npm for global installation
So, how do we get npm to install packages globally? As you correctly said, you should never, ever run yo with sudo. There are lots of different solutions to this problem and you can spend hours discussing their pros and cons religiously.
I personally dislike installing my user packages into the global /usr/ folder. /usr/ is for software that is shared across all users on the computer. Even if it's only using the machine, there are still good reasons to respect the way the Unix file system hierarchy is designed. For example if you decide at one point to wipe your whole node installation.
My preferred way of enabling npm to install packages globally without breaking out of $HOME is to set a local node prefix. This is as easy as running
echo 'prefix = ~/.node' >> ~/.npmrc
in your local shell. After that, you want to adjust your $PATH, to point to the new installation destination for global node executables by adjusting your favorite shell's config. E.g. by adding
export PATH="$PATH:$HOME/.node/bin"
to your ~/.bashrc. After that, you can happily run npm install -g generator-angular without sudo, without running into permission conflicts and if something is completely broken and you want to start from scratch, all you need to do is remove your ~/.node directory.
Thanks to #passy I managed to finally get this working on ubuntu 13.04 (in case anyone is having similar set up issues) with the following :
sudo apt-get update
sudo apt-get install python-software-properties python g++ make
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs
trying to run:
npm install -g yo
resulted in
Error: EACCES, mkdir '/usr/lib/node_modules/yo'
Fixed using:
echo prefix = ~/.node >> ~/.npmrc
echo 'export PATH=$HOME/.node/bin:$PATH' >> ~/.bashrc
. ~/.bashrc
Running:
yo webapp
resulted in:
Error: EACCES, permission denied '/home/username/.config/configstore/update-notifier-yo.yml'
Fixed using:
sudo chown yourusername:yourusername /home/yourusername/.config/configstore/update-notifier-yo.yml
hi in my case (on ubuntu 12.04), the prefix addition in ~/.npmrc did not changed anything.
if so, build the node package by yourself and install it in /opt/node or /home/user/.node.
I had an almost identical error involving a rogue .yo-rc.json file in my root directory from a project I installed earlier. Yeoman was switching cwd from the installation dir to root dir half way through the installation, but was only outputting the EACCESS permissions error without any details that the installation directory was /. It took ages to figure out why this was, and involved debugging through the Yeoman source, but I eventually learned that Yeoman will look up through the directory tree until it finds a .yo-rc.json, and generate the code there by calling chdir to the new location.
Yeoman should maybe check that the user has write permissions for the directory. Alternatively, it could mention in the output either that the cwd has changed, or print the name of the installation directory if where it finds .yo-rc.json is different than cwd.
The command for finding rogue .yo-rc.json files
sudo find / -name .yo-rc.json
From yoeman getting started page appears the command:
yo doctor
In my case, $NODE_PATH (which in my case, Ubuntu 14.04, is defined in /etc/profile.d) isn't the same than npm root. Adding in npm root in $NODE_PATH solve the problem.
I have been trying to get yeoman to play nice with my vagrant box and this is what I had to do to install npm packages globally without sudo on ubuntu:
1. Create the directory to store global packages
$ mkdir "${HOME}/.npm-packages"
2. Tell npm where to put any packages installed globally
Insert this snippet into your ~/.npmrc file:
prefix=${HOME}/.npm-packages
3. Make sure that npm can locate installed binaries et cetera
Insert this snippet into your .bashrc/.zshrc:
NPM_PACKAGES="${HOME}/.npm-packages"
PATH="$NPM_PACKAGES/bin:$PATH"
// `unset` `manpath` to allow inheritance from `/etc/manpath` with
// the `manpath` command
unset MANPATH // remove this line if you have previously modified `manpath`
export MANPATH="$NPM_PACKAGES/share/man:$(manpath)"
4. Run the following or restart terminal
$ source ~/.bashrc
Hope this helps anyone who finds themselves in a similar situation.
