Install script is broken

[Renemen64]

The install script by default install latest version pm2 (at now it is 4.20), this version depending a node-js v8 or higer, but script install v6.9.2.
So I fix it by replace "npm install -g pm2" to "npm install -g pm2@3.5.1"
Sorry for my bad english.

OP is correct you receive the following error during compile:

After applying this fix you can install properly.   Thank you!  I will make MPR on this shortly.
