Upgrade to NPM5 got error "Cannot find module 'delegates'"

[nmtuan200793]

I'm opening this issue because:

• npm is crashing.
• npm is producing an incorrect install.
• npm is doing something I don't understand.
• Other (see below for feature requests):

What's going wrong?
After I installed latest npm package by npm install npm@latest -g

I got the following error when run any npm command:
module.js:471
throw err;
^
Error: Cannot find module 'delegates'

So, could you please help me to resolve it?
Note that I upgrade from 3.00 -> latest version of NPM

You'll have to reinstall npm. I'm not sure why this would've happened and it's hard to figure out why, at this point. If you find that it's reproducible, please give us the details so we can look closer!

@zkat, how can I reinstall NPM?
I followed https://docs.npmjs.com/misc/removing-npm, but it still throws above error:
C:\Users\nmtuan>npm uninstall npm -g
module.js:471
throw err;

I just encountered this one when doing a clone and npm install of https://github.com/metamask/provider-engine

Same issue here, installing source-map-support in a project with a lot of dependencies right after I installed sqlite3.

npm 5.3.0
node 8.3.0
