Pm2-meteor deployment: can't install bcrypt -> invalid ELF header

So I am running into a very weird error I can’t seem to fix:

Deploying my (worker) app via pm2-meteor to my server, my app can not be started due to this error:

0|orderlio | Error: /opt/orderlion-worker/bundle/programs/server/npm/node_modules/detect-character-encoding/build/Release/icuWrapper.node: invalid ELF header
0|orderlio |     at Object.Module._extensions..node (module.js:682:18)

0|orderlio | Note: you are using a pure-JavaScript implementation of bcrypt.
0|orderlio | While this implementation will work correctly, it is known to be
0|orderlio | approximately three times slower than the native implementation.
0|orderlio | In order to use the native implementation instead, run
0|orderlio |
0|orderlio |   meteor npm install --save bcrypt
0|orderlio |
0|orderlio | in the root directory of your application.

But no matter what I do, this message always pops up.
I tried npm install -g bcrypt on my server, (obviously) I have bcrypt in my package.json … nothing is helping me solve this error.
Anyone ever experienced this?

Is this the first time Install on the server. I do not use pm2-meteor. I have faced this problem however. This usually indicates your server is missing a package to build bcrypt. Check the logs of pm2-meteor during ‘npm install’ step some error/warning should have been thrown.
