Incorrect NODE_PATH on win32

[henryykt]

On win32, running the eslint pre-commit hook with additional plugin fails.

For example using this test repository:

h@pc MINGW64 ~/workspace/github/node_path-pre-commit-test (master)
$ git remote -v
origin  https://github.com/henryykt/node_path-pre-commit-test.git (fetch)
origin  https://github.com/henryykt/node_path-pre-commit-test.git (push)

h@pc MINGW64 ~/workspace/github/node_path-pre-commit-test (master)
$ pre-commit run -av
[eslint] eslint..........................................................Failed
hookid: eslint

Oops! Something went wrong! :(

ESLint: 6.2.2.

ESLint couldn't find the plugin "eslint-plugin-prettier".

(The package "eslint-plugin-prettier" was not found when loaded as a Node module from the directory "C:\Users\henryt\workspace\github\node_path-pre-commit-test".)

It's likely that the plugin isn't installed correctly. Try reinstalling by running the following:

    npm install eslint-plugin-prettier@latest --save-dev

The plugin "eslint-plugin-prettier" was referenced from the config file in ".eslintrc.js".

If you still can't figure out the problem, please stop by https://gitter.im/eslint/eslint to chat with the team.

python version:

h@pc MINGW64 ~/workspace/github/node_path-pre-commit-test (master)
$ python -VV
