cannot find module 'readable-stream/transform' - node.js

Question

I'm trying to use to npm to install anything, and nothing works. I get the error code 'MODULE_NOT_FOUND' and 'cannot find module 'readable-stream/transform''.
I've tried uninstall and reinstalling nodejs. In the process I lost nodemon and now I can't even reinstall it because of this error.
This is the log of the error from Appdata/Roaming/npm-cache/_logs

npm install should install different modules but I just get errors instead.

I had the same problem, but it solved by taking long hours of googling.
The problem is a package named mississippi is outdated and cause the problem!
From you error log:
4 verbose stack at Object.<anonymous> (C:\Program Files\nodejs\node_modules\npm\node_modules\mississippi\node_modules\through2\through2.js:1:17)
Where you can some useful things about it: github#1809
Just remove the 'C:\Program Files\nodejs\node_modules\npm\node_modules' folder, unInstall the nodejs and npm and reinstall them again!
Additional information for Arch Linux users, that modules are not located under '/opt/local/lib/node_modules' as other distributions or installation mechanism, And so remove and installation of the nodejs and npm will not solve the problem!
sudo rm -rf /usr/lib/node_modules
sudo pacman -S nodejs npm
