Platform

Microsoft Windows NT 11.0.22621.0 x64

Subsystem

NPM / NPM.cmd

What steps will reproduce the bug?

Yesterday: npm install works and packages installed. (Environmental variables as-is)
Today: Running npm install generates Unknown command: "C:\Program Files\nodejs\npm" unexpectedly.
System change: ordering of environmental variables for Git/bin/bash v system32/bash.exe (unrelated) for another project (since removed in further troubleshooting).

Step 1: Attempt 1: Simple attempt

• I uninstalled NodeJs LTS v18 and upgraded to NodeJS and rebooted
• Used BulkCrapUninstaller to uninstall/remove traces from registry.

Step 2: Attempt 2: Clean Un-/Re- install: Git, Node LTS v20

• Removed Git 2.43 and Nodev20
• Scanned the registry for any npm or node references
• Removed all references in sysdm.cpl (runas:/ Admin) for Environmental Variables
  Then:
• Rebooted
• Installed Git, then NodeJs under Administrator runas/ elevated priviledges.
• Ran the commands as below.

Configured the following

• Git: c:\Program Files\git
• Node: c:\Program Files\nodejs
  • AppData : c:\AppData\Roaming\npm
  • Manually copied the c:\Program Files\nodejs\node_modules\npm ==> c:\AppData\Roaming\npm
• System Environments Variables and User Environmental Variables (see below)

How often does it reproduce? Is there a required condition?

node -v generates a version output to stdout: v20.10.0
npm -v generates a version output to stdout: v10.2.3

• but on Windows
  npm help => Unknown command: "C:\Program Files\nodejs\npm"
npm install => Unknown command: "C:\Program Files\nodejs\npm" or any oither
• but in WSL2 (Ubuntu): C:\Windows\System32\Bash.exe
npm help => works StdOut
  npm install => works StdOut

What is the expected behavior? Why is that the expected behavior?

npm commands should execute in Windows 11 from within Windows Terminal (Powershellv7)

However, I have WSL installed and from C:\Windows\System32\bash.exe it runs as expected. WSL was installed over 7 days ago and npm ran as expected and is running as expected..

I use Jetbrains IDEs and use their Run Configurations heavily and these IDE rely on C:\Program Files\nodejs\npm.cmd. (Actually I found out this issue happen that previously running scripts stopped running in this interface). I rely on these IDE Run Configs for current projects.

The script npm in C:\Program Files\nodejs is not being detected.

What do you see instead?

Running npm install or npm help generates Unknown command: "C:\Program Files\nodejs\npm"

• Irrespective of Reinstalling NodeJs several times.
• Configuring the Environmental Vars and
  • Ordered the nodejs and npm to top of paths
  • Added additional USER custom vars
    • NODE_PATH: directory level
      • C:\Program Files\nodejs
    • NODE_EXE: file level
      • C:\Program Files\nodejs\node.exe
    • NPM_PATH: directory level
      • C:\Program Files\nodejs
      • C:\Program Files\nodejs\node_modules
      • C:\Program Files\nodejs\node_modules\npm\bin
    • NODE_EXE: files level
      • C:\Program Files\nodejs\npm.cmd
      • C:\Program Files\nodejs\npm
      • C:\Program Files\nodejs\npx
      • C:\Program Files\nodejs\npx.cmd

Exceptionally by re-ordering (a failed smoke test)

Path=C:\Program Files\nodejs\node_modules\npm\bin;
C:\Program Files\nodejs\;
C:\Users\`$User`\AppData\Roaming\npm;

Generates : such suggest that the node/npm is detecting the package at some entry point but refuses to use the npm script..

npm help
node:internal/modules/cjs/loader:1147
  throw err;

Node.js v20.10.0

• Windows Compatibility troubleshooter.
• Autopatchng my user/system installed apps using WinGetUI 2.1.2

I have spent 4 to 5 hours trying to fix.
