I'm trying to install React through command prompt. NodeJS is already installed.
When I try to run this command:
npm i -g create-react-app
It is displaying error as shown below:
npm ERR! code ENOVERSIONS
npm ERR! No valid versions available for undefined
npm ERR! A complete log of this run can be found in:
npm ERR! C:\Users\xyz\AppData\Roaming\npm-cache\_logs\2019-12-10T10_51_39_2222-debug.log
Sometimes this can happen when you are using a private NPM registry / proxy registry and it has corrupted metadata. I've seen this happen with Sonatype Nexus 3 - there were corresponding error messages in the server logs.
Are you sure you have the right Node version? Try updating NodeJS or try running: npx create-react-app my-app
you should check this out issue .
If the problem still exist, please check your versions with this:
npm -v
node -v
对我来说,出现这个错误是因为我有一个我想要的包不存在的版本号。
