@Meeeeow could you post the actual terminal output for this, please? I'm not exactly sure which place it's coming from with just this info.

Thanks! This looks like a bug in npm itself. I'll look into it!

I had the similar issue. Got fixed just by cleaning the npm cache.

npm cache clean

[prat1477]

can anyone tell me how to fix this ????

[jrmcdona]

npm clean cache doesn't work. No NPM commands work. They are all result in this same error. Even npm -v

[patnaix]

running cmd through administrator works for me

I noticed that the path in the error message cut off prior to the first space. The path to my user folder is 'C:\Users\Paul Cyr'.

Changing the command from webpack --config webpack.config.js to node_modules\.bin\webpack --config webpack.config.js solved my problem.
