INIT_CWD does not get reset if `npm install` is invoked by another npm script

[jsg2021]

@Geod24 The tests are in npm/config@7070885 This is a bug in @npmcli/config, not in the cli itself.

This is maybe more of a question. But I was surprised by the fact INIT_CWD retained the parent process's value when a post-install script installed a child-directory project...

Hm, yes, it appears that I misread the npm v6 behavior.

How is INIT_CWD accessed now? I used it in my scripts on Windows like this, which always worked in version 6, but now doesn't anymore:

"scripts": {
    "format": "prettier-eslint --write %INIT_CWD%/src/**/*.{js,jsx}",
  },

I am using npm v7.5.3

If your shell is bash for windows:

"scripts": {
    "format": "prettier-eslint --write $INIT_DIR/src/**/*.{js,jsx}",
 },

But you shouldn't need that, just use "./src..."

Thanks @jsg2021 for the fast response.

You are obviously right that the easiest solution would be to use ./src. Unfortunately, prettier-eslint-cli requires an absolute path as parameter and does not accept relative paths to initialize it via npm scripts. Otherwise, it throws the error [ERR_ASSERTION]: 'basePath' should be an absolute path.

Using $INIT_DIR also does not work in version 7.5.3. For some reason, it does not get resolved. Neither do any of the other options like %INIT_CWD% $INIT_CWD $INIT_DIR %INIT_DIR% $PWD %PWD%

However, I finally found a workaround using cross-env-shell which resolves the paths correctly:

"scripts": {
    "format": "cross-env-shell prettier-eslint --write  %INIT_CWD%/src/**/*.{js,jsx}",
 },
