Why can I not install Node with Homebrew? - reactjs

I was able to download homebrew successfully. However, whenever I use 'brew install node' , I am getting the error message:
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink share/systemtap/tapset/node.stp
/usr/local/share/systemtap/tapset is not writable.
You can try again using:
brew link node
I have also tried 'brew link node' which results in:
Error: Could not symlink share/systemtap/tapset/node.stp
/usr/local/share/systemtap/tapset is not writable.
Can anyone help please?

The solution is in the official troubleshooting page of Homebrew. You have to give Homebrew the right to write inside /usr/local. To do this the official command to run is:
cd /usr/local && sudo chown -R $(whoami) bin etc include lib sbin share var opt Cellar Caskroom Frameworks
If you have not installed applications in /usr/local that rely on specific permissions, you can also run:
sudo chown -R $(whoami) /usr/local/*

opam init fails to verify certificate

On a completely fresh ubuntu 18.04 VM I tried to install opam:
$ wget https://github.com/ocaml/opam/releases/download/2.1.0/opam-2.1.0-x86_64-linux
$ mv opam-2.1.0-x86_64-linux opam
$ chmod 777 opam
$ ./opam init
And here is the error I got
<><> Fetching repository information ><><><><><><><><><><><><><><><><><><><><><>
[ERROR] Could not update repository "default": OpamDownload.Download_fail(_,

How should I solve this?
I ran into the same issue and I found a workaround on the OCaml forum: here. (Credits to UnixJunkie)
You can run:
opam init github git+https://github.com/ocaml/opam-repository.git
This should avoid the certificate issues. This worked for me.
I tried to fix the certificate issues using this answer as well. You could try doing that, but it seems complicated when the workaround is to simply point it to the github repo directly.
Update
The reason opam init failed for me was because curl was installed with snap on my system.
Try to run opam init -verbose and that could reveal more about why you ran into an error.
In my case I needed to install other things with opam and it kept failing every time. So snap uninstall curl and then sudo apt install curl fixed things. (Was only able to figure this out with the help from my professor)

Brew error: Could not symlink, path is not writable

When I try to install a library with homebrew (brew install aLibrary), I got the following error:
Could not symlink lib/pkgconfig/aFile
/usr/local/lib/pkgconfig is not writable.
What should I do?
There are several questions and answers (1,2,etc.) concerning this brew error, this is an attempt to make a general question as suggested here.
As explained here by Rick:
Start with brew doctor which will show you errors with your brew setup.
You might see something like this: "Warning: /usr/local/lib/pkgconfig isn't writable."
It will give you the advice that: "You should probably chown /usr/local/lib/pkgconfig".
This means: sudo chown -R $(whoami) /usr/local/lib/pkgconfig
Then you will need to link the files with this: brew link yourLibrary
If this does not work hopefully the output of brew doctor will give you enough to continue the search.
Giant Elk had a great suggestion and this is how I fixed my issue, which in my opinion is the cleanest. Users should not change permissions unless they know the ramifications.
Output your installed packages (via brew) to a text file:
brew list > brewlist.txt
Uninstall brew:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
Re-install brew:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Re-install previous packages (edit list if you do not need all packages):
brew install $(< brewlist.txt )
Use the following.
$ brew doctor
message will display error links to prune. If any found, run next option.
$ brew prune
once these are removed, proceed to link them agian
$ brew link python
I uninstalled brew, re-installed, then the issues went away.
You should simply give the permission to your account by running this command on terminal.
sudo chown -R $(whoami) (path)
In your case:
sudo chown -R $(whoami) lib/pkgconfig/aFile /usr/local/lib/pkgconfig

npm / yeoman install generator-angular without sudo

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.

Homebrew install permissions issue

I have a standard homebrew install inside of usr/local/
When I try:
Larson-2:~ larson$ brew install postgresql
Error: Cannot write to /usr/local/Cellar
And when I use sudo:
Larson-2:~ larson$ sudo brew install postgresql
Cowardly refusing to `sudo brew install'
What am I doing wrong?
You somehow have limited permissions to /usr/local/Cellar. Brew doesn't like to install with sudo which is why it refuses.
Check the permissions:
ls -ld /usr/local/Cellar
Open them up for writing:
sudo chmod a+w /usr/local/Cellar
Do not use sudo when working with brew (for security reasons).
You've to simple set-up your permissions.
So I would go even further and change the permissions to:
sudo chgrp -R admin /usr/local /Library/Caches/Homebrew
sudo chmod -R g+w /usr/local /Library/Caches/Homebrew
and then apply the specific group (either admin or staff) to user which should be allowed to use brew command. Check groups of your user via: id -Gn).
If there are further issues, run: brew doctor to see what's wrong.
I'd change the group permissions:
$ chgrp -R admin /usr/local/Cellar
$ chmod g+w /usr/local/Cellar
assuming your user account is in group admin.
This also happens if you have multiple users on your machine. If so, it would be best for you to change the user since every other approach would have you messing around with a lot more files and folders than just /usr/local/Cellar
Use su userWhoInstalledBrew.
The problem can be solved by changing the directory's owner to the current user:
sudo chown -R $USER /usr/local
This answer is taken from: https://github.com/Homebrew/homebrew/issues/17884
Following the advice chukcha14 provided in his answer at There is no Cellar file in my usr/local dir for brew, I did this:
jaimes-mbp:SMR jaimemontoya$ brew install mongodb-community#4.2

You may encounter build failures or other breakages.

Lost ability to run as sudo following MacPorts upgrade

I recently updgraded MacPorts from 1.9.2 to 2.0.3. Since then, I've lost the ability to run as sudo.
sudo: can't stat /opt/local/etc/sudoers: No such file or directory
sudo: no valid sudoers sources found, quitting
Unsure if these are related, but I'm wondering what the best course of action is at this point.
port installed returns
sudo #1.7.4p2_0
sudo #1.7.7_0 (active)
Further investigation suggests I've installed MacPorts' sudo without an accompanying /opt/local/etc/sudoers file. I've managed to create such a file using visudo, copying the content of /etc/sudoers, chmod to 0440 and ownership to root:wheel.
I guess the question now is whether I should use MacPorts' sudo or uninstall it? And how did I end up with installing the MacPorts' sudo?
Not a Mac man myself, but have a look at this page:
http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man5/sudoers.5.html
...and also a look at the man page for visudo, which is used to edit the sudoers file:
http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man8/visudo.8.html#//apple_ref/doc/man/8/visudo
