hi @Stanzilla thanks for bringing it to our attention.

Can you please open a new issue providing more info about the current environment, how exactly do you setup that Ubuntu WSL, how did you installed Node.js and npm. Also when you run an npm command can you use a more verbose logllevel. e.g: npm install --loglevel=silly. All that can be helpful for us to track down what might be happening in this case.

I'm going to close this issue since it's been stalled for a long time and haven't got any more traction but like I said, feel free to create a new one with more info in case you're able to still reproduce it using the current version of the npm cli (npm @8.5.2 at the time of writing).

@ruyadorno Hey there! I just updated npm to 8.5.2 and ran npm install --loglevel=silly which resulted in this:

npm verb stack Error: EISDIR: illegal operation on a directory, lstat '\\wsl$\Ubuntu\home\stan\projects\personal\WeakAurasCompanion\node_modules\.bin\apollo-pbjs'

Afterwards I nuked node_modules and did it again and it failed here:

Everything else is pretty much the same, so not sure if a new issue would help.
