Error during NPM install PM2 -g (Ubuntu 14.04 x64)

Question

I am getting an error whilst trying to run npm install pm2 -g on a cloud Ubuntu 14.04 microserver/droplet.

I've tried:

sudo npm install pm2 -g

and

npm cache clear -f

...followed by both sudo and non-sudo installation attempts. All result in the below.

Verbatim outcome:

npm ERR! git clone --template=/root/.npm/_git-remotes/_templates --mirror http://ikt.pm2.io/ikt.git /root/.npm/_git-remotes/http-ikt-pm2-io-ikt-git-4d23bf0d: undefined

Is the Git repo b0rked? I'm quite new to SSH/Linux servers etc so this is all probably very obvious... :/

Answer 1

Figured it out: turned out it had installed ok.

The above was misleading as it a) looked as though it'd not completed properly, and b) trying to run any PM2-based command immediately afterwards was resulting in an error.

But it's now working.
