Error: no module named javalang

Hello,
we tried to run SourcererCC on zip java project and we got this error:

Traceback (most recent call last):
File "tokenizer.py", line 12, in
import javalang
ImportError: No module named javalang

then we tried with different java project and we got the same error

[crista]

Did you install that module?

This can be solved by running sudo pip install javalang (my OS is ubuntu)
