'notsup' error during npm install

I don't understand what the problem is, but here's the log after I try to run npm install immediately after cloning the repo:

Debug log: npm-debug.zip

> npm install

I know this is shown above, but just in case:

webserver@PSEWS1:~/stuff/login-flow$ nodejs --version
v4.2.6

webserver@PSEWS1:~/stuff/login-flow$ npm --version
3.5.2

And finally:

webserver@PSEWS1:~/stuff/login-flow$ uname -a
Linux PSEWS1 4.4.0-31-generic #50-Ubuntu SMP Wed Jul 13 00:07:12 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

webserver@PSEWS1:~/stuff/login-flow$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.1 LTS
Release:    16.04
Codename:   xenial

I have no idea what to do. Any information would be helpful.

Edit: I thought of something rather important that seems to be one of the primary problems. I'm running this on a VMWare instance. The host OS is Windows Storage Server 2012 R2 64 bit and the guest OS is Ubuntu 16.04.1 LTS 64 bit as seen above.
