Unhandled rejection error on npm uninstall/remove

[bubblecup]

I'm opening this issue because:

• npm is crashing.

What's going wrong?

On npm remove, I get an Unhandled rejection Error: Argument #2: Expected string but got null with the following stack trace:

possibly related to #17497? This is the same error I receive for npm uninstall -g

[sjones6]

I just received the same error:

npm uninstall -g babel resulted in the following error:

NPM: 5.0.3;
Node: 8.1.3

Appears to be the same as the others.

@sjones6 - try updating npm. 5.1.0 included a fix that solved the issue for me (#17590)

[kenany]

Yeah, I do believe this is resolved in npm@5.1.0. Could you give it a shot, @bubblecup?

[bubblecup]

Works great, thank you... and closed.
