问题


When I run npx create-react-app appname I get the following error message:

You are running `create-react-app` 4.0.0, which is behind the latest release (4.0.1).

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/

npm ERR! code 1

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/hat/.npm/_logs/2020-11-23T06_53_20_858Z-debug.log

I then ran npm uninstall -g create-react-app and got the following output:

up to date in 380ms

found 0 vulnerabilities

After running npm uninstall -g create-react-app command I ran npx create-react-app appname and I got the same error message as above.

This is what the error log located in /Users/hat/.npm/_logs/2020-11-23T06_53_20_858Z-debug.log looks like:

I ran npm cache clean --force to clear the cache. The out after running this command was npm WARN using --force Recommended protections disabled.

I'm running

  • node version: v15.2.1
  • npm version: 7.0.8
  • npx version: 7.0.8
  • OS: maOS CAtalina 10.15.7
  • Im using vvm version 0.35.3 to manage my node versions

I also noticed that when I downgraded my node version to v14.1.0, npm and npx was automatically downgraded to 6.14.6. I then ran npx create-react-app appname and the command worked. I was able to create react app.

Is there a bug with node v15.2.1? It just doesn't make sence


回答1:


I have the same problem. I fixed it with

npm install -g create-react-app

After that npx create-react-app worked.




回答2:


I had this problem. Apparently, global installation of 'create-react-app' is no longer supported. So what I did was: 'npm install create-react-app' instead of 'npm install -g create-react-app'. Then npx create-react-app worked.
