I attempted to update npm via different means (console and npm-windows-upgrade), ended up with multiple installations and decided to uninstall everything, clear the path and start over again.

After installing the newest lts version via the installer from https://nodejs.org/en/ npm and node versions are displayed correctly

node -v
v16.14.2

npm -v
8.5.0

Now running npm install results in the error

I am a bit of a loss on why npm does not find the correct module. Do I have to explicitly set a path to the nodejs directory are there config file conflicts left over from the previous install?

I would like to understand the culprit so it can be properly fixed and not cause issues with global installation of packages down the line.

Npm run in the console is actually the one installed with nodejs:

PS C:\Users\Kilian\git\FooBar> gcm npm  

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Application     npm.cmd                                            0.0.0.0    C:\Program Files\nodejs\npm.cmd

CodePudding user response：

In my case the issue resolved itself after doing a simple npm install on a fresh initialized repo. I can not tell if this finally solved the issue or if it was something else but now it is working again.

CodePudding user response：

That's good you managed to resolve it!

It could be possibly related to some cache issues or package-lock.json content, next time it happens you could try removing the lock file and/or cleaning npm cache.
