This problem has created and still is creating a lot of headaches:

Basically the suggestion is correct, may be you have an old version of something around, first try to remove the global create-react-app

npm uninstall -g create-react-app

Then try to update the npm and all the packages.

npm install -g npm@latest

Then you can run to create react app again.

npx create-react-app my-app

This has solved the issue in my case

Answer 2

global installs of create-react-app are no longer supported.

do it:

npm uninstall -g create-react-app

now do it:

npm install create-react-app

now create your app

npx create-react-app yout-app-name

Answer 3

Check the names of the scripts in the package.json file, they may be called something different to start. e.g. this part:

"scripts": {
  "build": "cd packages/react-scripts && node bin/react-scripts.js build",
  "start": "cd packages/react-scripts && node bin/react-scripts.js start",
},

Also, try printing your working directory using pwd and check to see if the current directory is correct and run npm run start again.

I had this problem and managed to fix it by removing the create-react-app with this the npm uninstall -g create-react-app command. This ensured that the npx would always use the latest create-react-app version.

Answer 5

Installing create-react-app globally is now discouraged. Instead uninstall globally installed create-react-app package by doing: npm uninstall -g create-react-app (you may have to manually delete package folder if this command didn't work for you. Some users have reported they had to delete folders manually)

Then you can run npx create-react-app my-app to create react app again.

Answer 6

Just in case. From the docs:

If you've previously installed create-react-app globally via npm install -g create-react-app, we recommend you uninstall the package using npm uninstall -g create-react-app to ensure that npx always uses the latest version.
