With the latest stable Rocket Chat (0.60.3) on Centos 7 machine I got this error :

# node main.js
/opt/Rocket.Chat/programs/server/boot.js:50
    const { pause } = require("./debug.js");
          ^

SyntaxError: Unexpected token {
    at exports.runInThisContext (vm.js:53:16)

    at Module._compile (module.js:409:26)
    at Object.Module._extensions..js (module.js:416:10)

This can be fixed by installing a few dependency (magic)

npm install -g inherits n

Then it seems to be recommended to run node.js 8.9.3 :

n 8.9.3

After that I got greeted with a well-known issue on Centos … the older GLIBC librarys :

[root@rocket Rocket.Chat]# node main.js
module.js:664
  return process.dlopen(module, path._makeLong(filename));
                 ^

Luckily in this case there is a quick and easy workaround, install some build apps in case they are missing :

yum install g++ build-essential

If these are not available you can try :

yum install gcc gcc-c++ make openssl-devel

rebuild node-gyp :

npm install -g node-gyp
cd /opt/Rocket.Chat/programs/server/node_modules/fibers/
node-gyp rebuild
cp -f build/Release/fibers.node bin/linux-x64-57/fibers.node

And rocketchat will boot up again 😀 jippie !

systemctl start rocketchat.service

Happy rocketing ! 🙂

Thanks to stally!
