MultiJson AdapterError Rails 4 Ruby 2 Passenger

Question

I am trying to set up rails on aws (Dev env works fine). It is not possible to start production correctly. Can shell in and db look good. I looked into my log file and I get the following error.

rake aborted!
MultiJson::AdapterError: Did not recognize your adapter specification (cannot load such file -- json/ext/parser).

You have MultiJsonboth Jsongems installed and in the gemlock file.

This happens during asset compilation.

After solving the situation when I could not return the version, I found another solution to the problem.

We are simply missing out on the corresponding dependent pearls. This helped me fix this without downgrading:

gem install json

Hope this also helps other people with this problem. I came from Google, so hopefully there will be other people too.
