Installation issue: “python setup.py egg_info” failed with error code 1

问题

I get the following error after running pip install rpy2 on a mac with OSX 10.11.2 and Python 2.7.12:

Collecting rpy2
  Downloading rpy2-2.8.2.tar.gz (186kB)
    100% |████████████████████████████████| 194kB 3.0MB/s
    Complete output from command python setup.py egg_info:
    Warning: Tried to guess R's HOME but no command (R) in the PATH.

    ----------------------------------------

I have also tried running it with sudo:

Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-build-FDFFDI/rpy2/

I have tried pip install --upgrade setuptool and upgrading pip to latest version but nothing seems to work.

Could you please help?

Thank you.
