[BUG] npm does not find executables from other packages if package using it is installed from local directory

[mlederhi]

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

Npm does not find executables registered in the "bin" section of package a, needed by package b if package b is installed from a local directory (and thus symblinked into the node_modules directory).

Expected Behavior

Npm does find executables.

Steps To Reproduce

bug.zip

1. Extract bug.zip
2. cd bug
3. mkdir install
4. cd install
5. npm install ../pkg_a
6. npm install ../pkg_b
7. cd node_modules/pkg_b
8. npm run build

Output of step 8:

> pkg_b@1.0.0 build
> echo $PATH; builder

/home/lederhi/Downloads/bug/pkg_b/node_modules/.bin:/home/lederhi/Downloads/bug/node_modules/.bin:/home/lederhi/Downloads/node_modules/.bin:/home/lederhi/node_modules/.bin:/home/node_modules/.bin:/node_modules/.bin:/home/lederhi/Downloads/node-v16.13.1-linux-x64/lib/node_modules/npm/node_modules/@npmcli/run-script/lib/node-gyp-bin:/home/lederhi/Downloads/node-v16.13.1-linux-x64/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/bin:/usr/lib/llvm/12/bin
sh: line 1: builder: command not found

Note: wrong PATH generation happens probably because packages are symlinked into the node_modules directory upon package installation. If I replace the symlinked package with a real copy of the package, then it works.
