[BUG] npx appears broken in 7+ with PATH

[dl748]

test.zip

Current Behavior:

Version 6+

export PATH=$(pwd)/node_modules/.bin:$PATH
$ webpack --version
4.44.2
$ npx webpack --version
4.44.2
$ cd common
$ webpack --version
4.44.2
$ npx webpack --version
4.44.2

Version 7+

export PATH=$(pwd)/node_modules/.bin:$PATH
$ webpack --version
4.44.2
$ npx webpack --version
4.44.2
$ cd common
$ webpack --version
4.44.2
$ npx webpack --version
Need to install the following packages:
  webpack
Ok to proceed? (y)

Expected Behavior:

Should not ask to install as it already exists in the PATH

Environment:

OS: Linux 5.7.9
Node: v14.15.4
npm: 7.5.2

@dl748 does the common folder happen to have a node_modules folder there? Sounds like that could be the issue.

[dl748]

@darcyclarke No it does not

Is NPX following its own rules now and NOT following the PATH variable like the documentation says?

PATH=/myproject/node_modules/.bin:/usr/.local/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/var/lib/snapd/snap/bin

if i put webpack into /usr/bin/webpack. npx works... if i put it in /usr/.local/bin/webpack.. it doesn't work.. which seems to me that its building it OWN path to look for the program and completely ignoring the PATH variable which is way different than the 6 and the documentation.

By default, npx will check whether <command> exists in $PATH, or in the local project binaries, and execute that. If <command> is not found, it will be installed prior to execution.

which is NOT what its doing

Simple script to replicate

test123

#!/usr/bin/env node

console.log('test')

$ chmod 755 test123 # make executable
$ mkdir x
$ mv test123 x/.
$ export PATH=$(pwd)/x:$PATH
$ test123
test
# Above works
$ npx test123
npx test123
npm ERR! could not determine executable to run

npm ERR! A complete log of this run can be found in:
npm ERR!     /User123/.npm/_logs/2021-03-04T05_12_18_738Z-debug.log
$ npx --version
7.6.0
$ sudo npm install -g npm@6.14.11
$ npx --version
6.14.11
$ npx test123
test
# works with 6.14.11

Note: the reason I use npx instead of just calling the script is for windows support webpack works for *nix/osx but not for windows since it needs to run webpack.cmd instead on windows

npm will not look in the PATH environment variable for things to run. IT will only check the folders it knows about that are related to npm itself. Adding the node_modules/.bin folder to your PATH is not recommended. You should run npm scripts from npm/npx.
