Minifer.js not found; nodebb.min.js not created

  • I'm seeing the following error when starting NodeBB on my production server:

        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



Looks like your connection to NodeBB was lost, please wait while we try to reconnect.
