Creating the react app issue with npm - reactjs

I tried creating the new react app and for that i have followed the reactjs command to install like npm install -g create-react-app. But its not working and i am getting the error as npm ERR! Cannot find module 'pseudomap'. So for that i have uninstalled the nodejs 3 times and installed freshly. But still no luck for me. Can anybody provide any solution for this.

npx create-react-app has suddenly stopped working

I've been running 'npx create-react-app' for my projects for the last few months however today when I tried to run the command to create a new project I got this error:
Error Message
I've tried clearing my cache, running 'npx create-react-app#latest' with no luck so far.
Try clearing legacy-peer-deps
npx create-react-app myapp --legacy-peer-deps
I recently tried creating a new React project on React 18 with create-react-app and ran into this.
The following worked for me:
Open the project via vs code (or any other terminal) and run the npm install command again to install the dependencies:
npm install
If after running the above command, the same error still persists, try:
npm install --legacy-peer-deps
It's a bug, we have to wait until the next update but you can try to install it and remove the node_module and after change the react-dom and react to a lower version like 17.0.2

Why can't I start a React project with npx?

I'm going in circles with npx trying to start a new project. Here's what I get:
"PS C:\Users\John\Documents\WebSites\react_projects> npx create-react-app material-ui
Need to install the following packages:
create-react-app
Ok to proceed? (y) y
"You are running create-react-app 4.0.3, which is behind the latest release (5.0.0).
"We no longer support global installation of Create React App.
Please remove any global installs with one of the following commands:
npm uninstall -g create-react-app
yarn global remove create-react-app
The latest instructions for creating a new app can be found here:
https://create-react-app.dev/docs/getting-started/"
When I type npm uninstall -g create-react-app, I get "up to date, audited 1 package in 495ms. found 0 vulnerabilities."
So I try to create the app again with npx, and I get this:
"Need to install the following packages:
create-react-app
Ok to proceed? (y)"
So I press y, and I get the first error message again. I just go in circles. How can I fix this?
Refer to official reactjs website you need to have ""Node >= 14.0.0 and npm >= 5.6"" on your machine. https://reactjs.org/docs/create-a-new-react-app.html .
Also yarn create is available in Yarn 0.25+
so you might want to check these versions
npm
stands for node package manager. It helps to install, migrate apps by adding dependencies in package.json file. You only need to run npm i. For example in react API call npm i axios you should run and import in file in order to use axios features. Also all you need to have is package.json following dependencies and packages will be added(except node_modules folder as it comes with packages and more in size).
You can use npm to start, build, eject, watch and test.
npx is a CLI tool which provide way to install and manage dependencies hosted in npm registry. It is bundled with npm since 5.2.0v. It is helpful in installing and getting started with frontend JS libraries like reactjs, angularjs, vuejs, Sveltejs or boilerplate apps.

How can i solve "No project found" error when installing react

I am new to react and i am taking my first course on openclassrooms on react.
The instructor is using the command
yarn global add create-react-app
to setup but when i run the commdand i get the error below
Usage Error: No project found in /E:/Web Dev/React/react-project
i have tried to use the command below that is provided in the react documentation but i stil get the same error
yarn create react-app my-app
How can i solve the problem i have looked up on the react documentation but still cannot find the solution.
I experienced the same issue and solved it as follows:
Uninstall yarn from npm using npm uninstall -g yarn
Install Yarn from Installation - Yarn Classic
Restart PowerShell / CMD
Before performing the above steps yarn --version printed 2.0.0-rc.27 on my machine. Now it prints 1.22.4.
Having Yarn 2.x globally installed is discouraged accourding to Installation - Yarn 2.x.

NPM peer dependencies error

Im doing this tutorial on angular js. Im a complete newbie and have never touched it before but would love to learn. I am doing this tutorial here
https://www.youtube.com/watch?v=ofASsumsf7E
However im having issues when trying to run the npm install command. This is the error that i am getting.
npm WARN peerDependencies The peer dependency grunt#~0.4.0 included from grunt-c
ontrib-copy will no
I have no idea how to debug this but its a big roadblock for me. I can try to find other tutorials but I like this one. Can somebody help?
peerDependencies are deprecated in the latest npm versions. This is why you have the warning.
When you use gruntyou install it locally (which isn't the case in that project from what I can see : https://github.com/colorfest/angularjs/blob/master/package.json).
You may have to run npm install grunt at the root of the project.
