Failed at the core-js postinstall script error

Question

I am facing the following errors when I try to install node modules in an existing Angular project. I am trying to install the node modules in windows machine(Win32 X64).

       > core-js@2.6.12 postinstall node_modules\babel-runtime\node_modules\core-js 
       > node -e "try{require('-/postinstall')}catch(e){}"

      npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.2.13 (node_modules\ng-cli-pug-loader\node_modules\fsevents):

      npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

      C:\Users\test\AppData\Roaming\npm-cache\_logs\2021-06-23T16_43_06_961Z-debug.log

The following are the versions installed in my system

  AngularCli : 8.3.29
  Node : 14.17.1
  NPM: 8.2.12

I have tried deleting node modules folder and running npm cache clean --force and reinstalling node modules , also tried uninstalling nodejs and deleting the npm-cache folder and reinstalling again.

Still I am facing the same issue. Any help would be appreciated.

Show us the whole error. This is just one line which doesn't show the problem. — 0xLogN, Jun 23 '21 at 18:59
Does it really say "ENDENT" or does it say "ENOENT"? Is this Linux or macOS or Windows? — 0xLogN, Jun 24 '21 at 04:00
Hi @LoganDevine , I have corrected it . It is `ENOENT` . I am using windows 10 machine 64 bit — Shaik Nizamuddin, Jun 24 '21 at 08:27
So it appears it's assuming you are on Linux as it tries to spawn bash. Is there *anything* weird about your version? Is your architecture "x64" or "x86_64"? — 0xLogN, Jun 24 '21 at 14:41
@LoganDevine , My windows system type is: 64-bit operating system, x64 based processor. I have cloned the repo from bitbucket and run npm install . My other teammates having same configuration it is working fine for them. — Shaik Nizamuddin, Jun 24 '21 at 14:50

This error means that the postinstall script is fork-and-exec'ing bash, which is not present on Windows. You need to run this from a Bash emulator like MINGW64 (Git Bash).
