Also it looks like the redis version is a little old, you might want to upgrade that too: https://community.nodebb.org/topic/5935/problem-with-redis-upgrade
Minifer.js not found; nodebb.min.js not created
I'm seeing the following error when starting NodeBB on my production server:
module.js:340 throw err; ^ Error: Cannot find module '/minifier.js' at Function.Module._resolveFilename (module.js:338:15) at Function.Module._load (module.js:280:25) at Function.Module.runMain (module.js:497:10) at startup (node.js:119:16) at node.js:935:3
The same code runs correctly on dev and our staging server (Heroku). We are running on Ubuntu and NodeBB is being started by Upstart. As far as I can tell the minifer code is in place - this is the file on the prod server:
1623 Mar 21 12:39 minifier.js
I've run npm install in the nodebb folder and everything is up to date. Here is the verbose log from NodeBB:

The log always stops at this point. It seems to be the case that the following line in webserver.js fails:
async.apply(!skipJS ? meta.js.minify : meta.js.getFromFile, app.enabled('minification')),
The user running nodeBB has write permission to the /public folder where the nodebb.min.js will be created.
Interestingly, if I manually add the nodebb.min.js to the /public folder, hack that line to force meta.js.getFromFIle, NodeBB starts but the login page is blank apart from the header and there are no JS script errors.
It's failing on this line in /src/meta/js.js:
var minifier = Meta.js.minifierProc = fork('minifier.js', , forkProcessParams),
Are there some special permissions or configuration I need to setup to allow a process to be forked?
I've tried running node with each of the following command lines, both giving similar results:
exec node $LIVE_DIR/loader.js --no-silent --no-daemon >> /var/log/blahblahblah/nodebb.log exec node $LIVE_DIR/app.js >> /var/log/blahblahblah/nodebb.log
Found the answer - The script starting NodeBB must be in the nodebb directory otherwise the minifier will fail as above. Changed my Upstart script as follows:
cd $LIVE_DIR exec node app.js >> /var/log/blahblahblah/nodebb.log
