How to instal rpy2 on mac OS - Library not loaded:

Question

This is proving to be very difficult on mac os and python3.

Below is are the paths for R. I have them and pointed to them. So why the problem?

From the command line:

1) which R

   /usr/local/bin/R

2) R RHOME

/Library/Frameworks/R.framework/Resources

In python:

    import os,sys
    sys.path.append('/usr/local/bin/R')
    sys.path.append('/Library/Frameworks/R.framework/Resources')
    os.environ['R_HOME'] = '/usr/local/bin/R'

    import rpy2.robjects as robjects

    from rpy2.rinterface._rinterface import (baseenv,
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/rpy2/rinterface/_rinterface.cpython-36m-darwin.so, 2): Library not loaded: /Library/Frameworks/R.framework/Versions/3.5/Resources/lib/libR.dylib
  Referenced from: /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/rpy2/rinterface/_rinterface.cpython-36m-darwin.so
  Reason: image not found

Here is the rpy2 version:

import rpy2
print(rpy2.__version__)
2.9.4

How I installed:

 pip3 install rpy2

Mac Version:

 10.14 Mojave

python3 version:

  which python3
  /Library/Frameworks/Python.framework/Versions/3.6/bin/python3

R version:

R --version
R version 3.4.4 (2018-03-15) -- "Someone to Lean On"
Copyright (C) 2018 The R Foundation for Statistical Computing
Platform: x86_64-apple-darwin15.6.0 (64-bit)

So, you've focused on R being the issue but you haven't told us anything about the Python configuration. how you installed it? etc. There's a guess due to the error but my python 3.7 is not in `/Library`. We also don't know your macOS version. I grok the frustration (Python is the source of most if not all evil in the universe) but I think you need to provide more info to get aid. — hrbrmstr, Nov 13 '18 at 02:53
