node server works; node wiki.js start does nothing

[sammyjava]

Actual behavior

$ node server fires up the wiki on the configured port and all is well.
$ node wiki.js start provides an assuring message ✔ Wiki.js has started successfully. but the Wiki has not started.

Expected behavior

$node wiki.js start fires up the wiki.

Steps to reproduce the behavior

1. install wiki.js
2. configure with port=49157 (don't ask)
3. $node wiki.js start -- nothing happens
4. $node server -- wiki fires up.

This is under CentoOS 7 using the repo version of node

[root@fisher wiki-js]# rpm -q --whatprovides /usr/bin/node
nodejs-6.14.2-1.el7.x86_64
[root@fisher wiki-js]# node --version
v6.14.2

Look for errors by using node server.

If there're none, then there's an issue with pm2.
You can try installing it manually npm i pm2 -g
Then run pm2 start server -n wiki

Thanks, that helped me figure out sort of what's going on. I had re-installed wiki.js to a new directory /var/www/wiki-js, but somehow, somewhere, the old directory /var/www has "stuck". pm2 indicates two locations, the one that node wiki start will start (/var/www) and the one within which it will not start (/var/www/wiki-js). I'm running it out of /var/www again so it works, but I don't see why it thinks I have two wiki.js installs.

The earlier error showed that the /var/www/wiki-js version was still looking for ProcessContainerFork.js in /var/www/node_modules rather than /var/www/wiki-js/node_modules.
