Answer 1

This is possibly due to the dev package which gets installed with npm and this problem generally occurs with Mac OS.

Run the below command to remove the dev package.

npm uninstall dev --save

I hope I'm able to help with this answer.

I got the same error using nom, but I tried with Yarn, it worked.

$ npm i dev jest
  npm WARN deprecated istanbul-lib-hook@1.2.1: 1.2.0 should have been a major version bump
  npm ERR! code EBADPLATFORM
  npm ERR! notsup Unsupported platform for inotify@1.4.2: wanted {"os":"linux","arch":"any"} (current: {"os":"darwin","arch":"x64"})
  npm ERR! notsup Valid OS:    linux
  npm ERR! notsup Valid Arch:  any
  npm ERR! notsup Actual OS:   darwin
  npm ERR! notsup Actual Arch: x64

But then I tried with yarn

$ yarn add --dev jest

This might not have fix the problem with npm but it fixed this error for me
