Create-React-App, Installation Error ("Command Not Found")

You are able to apply the following solution:

$ npm config set prefix /usr/local
$ sudo npm install -g create-react-app
$ create-react-app my-app

The environment variables are not set properly. When you run the create-react-app it shows you a path along with the error. Copy that path and add it in the environment variable.

Alternatively you can use the command:

npx create-react-app <app_name>.

This will do the work for you.

Try this. It worked or me. I found this in the React documentation. "Npx" is not a typo. It's a package runner tool that comes with npm 5.2+.

npx create-react-app my-app

Install Nodejs & npm

sudo apt update
sudo apt install nodejs
sudo apt install npm

if you install maybe show you this like errors for Reactjs setup.this helpful for you

npm install -g create-react-app


npm ERR! code EACCES
npm ERR! syscall mkdir
npm ERR! path /usr/local/lib/node_modules/create-react-app
npm ERR! errno -13
npm ERR! Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/create-react-app'

then When you type after this

create-react-app test-react-app 

Show you in terminal zsh: command not found: create-react-app

you fix this error by using this command

sudo npm install -g create-react-app
create-react-app test-react-app

I hope work fine for you also.

Use npx instead of npm.

Answers given above are right but I want to share some things that I also faced and these are basics.

To setup react project

If you want to create a node environment

$ sudo apt-get update
$ sudo apt-get install nodejs

(Sometimes we can also run without sudo; but sudo means install in system level.)

$ sudo apt-get install nodeenv

$ nodeenv env
$ source /bin/activate

If you want to create new react app then

$ npm install create-react-app

If an error occurs create-react-app: command not found then install with -g, it happens because node is installed globally and it is not getting the node in local

$ npm install -g create-react-app

$ create-react-app app_name
$ cd app_name
app_name$ npm start

I hope you already installed Node package manager(npm). now run npm install -g create-react-app, if everything fine then you can use create-ract-app command. if you are getting any permission error just sudo npm install -g create-react-app.

I hope it will work. Happy Hacking.

if you face following this problem:

create-react-app: command not found

solution:

  sudo npx create-react-app react_spa
  cd react_spa
  sudo npm start

I hope its work.

This is how I get it fixed.

1. Step # 1:- Make sure, Node js and React js is installed globally. You can check Nodejs by node --version . If not installed, install and run export PATH=$HOME/.node_modules_global/bin:$PATH
2. Step # 2:- Clean your npm cache by following the command npm cache clean --force
3. run sudo npx create-react-app your-app-name

And that's it. you're done.

Please note, This solution worked for me for MAC OS

I tried all methods listed above and in other sites. They weren't working for me. But for some reason I decided to add the create-react-app directory into my system variables as a last ditch method and to my surprise this actually worked.

If above answers are not working, then try this

1. update the npm version (npm install npm@latest -g)
2. clear the cache (npm cache clean --force)
3. create the react project (npx create-react-app myapp) (while running the 3rd command, make sure that create-react-app is already installed in the pc)
