cygpath not found on windows with MINGW shell

What I Wanted to Do

eslint cannot run from bash shell on Windows because cygpath is not found.

What Happened Instead

sh.exe"-3.1$ ./node_modules/.bin/eslint --version
./node_modules/.bin/eslint: line 5: cygpath: command not found
internal/modules/cjs/loader.js:583
    throw err;
    ^

Error: Cannot find module 'd:\eslint\bin\eslint.js'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:581:15)
    at Function.Module._load (internal/modules/cjs/loader.js:507:25)

Reproduction Steps

See above

Details

Anyway, commenting the following lines in ./node_modules/.bin/eslint makes eslint works without problems:

case `uname` in
    *CYGWIN*|*MINGW*|*MSYS*) basedir=`cygpath -w "$basedir"`;;
esac

I reinstalled MINGW and MSYS just to see if cygpath is installed with some package, but was unable to find it (also the package cygutil does not provide cygpath). I suggest to change the case to detect only *CYGWIN* or remove it altogether.

The workaround is to change in my scripts ./node_modules/.bin/eslint to node ./node_modules/eslint/bin/eslint.js

Platform Info

Tell us about your environment

  • ESLint Version: 6.3.0
  • Node Version: 10.15.0
  • npm Version: 6.11.3
    Windows 10 64bits
    Using MSYS and MINGW (unknown version) to emulate Unix shell
$ npm --versions
<!-- paste output here -->
$ node -p process.platform
win32
<!-- paste output here -->

Same problem with ncu installed globally.

cygpath is not needed in MinGW and MSYS because these systems magically convert paths in the right way.

So please fix this. I cannot use anymore any npm installed program after the last upgrade.

Thanks!
