You can’t run npm run eject twice in create-react-app?

While doing React development with create-react-app, I was curious about the webpack configuration, so I tried running npm run eject. I looked over the configuration and then reverted it with git checkout -f, but… I could never run npm run eject again.

The npm log didn’t have any useful information.

  14   │ 12 verbose stack spawn ENOENT
  15   │ 12 verbose stack     at ChildProcess.<anonymous> (/usr/local/lib/node_modules/npm/node_modules/npm-lifecycle/lib/spawn.js:48:18)

  18   │ 12 verbose stack     at Process.ChildProcess._handle.onexit (internal/child_process.js:288:5)

There was no solution on Stack Overflow either. So I figured it out on my own and found a fix. The method is simple.

npm uninstall react-scripts
npm install react-scripts

Just run them in order. Done.
