rpy2 rinterface Library not loaded: @rpath/libicuuc.54.dylib/image not found

Hallo,

I installed python 3.6 and r and rpy2 r-wgcna via conda and iterativeWGCNA via pip on my mac.

when I run iterativeWGCNA I get the following error. the same happens when I download and install the version from git.

Traceback (most recent call last):

Hi-

This appears to be an anaconda issue:

ImportError: dlopen(/Users/silas/anaconda3/envs/wgcna/lib/python3.6/site-packages/rpy2/rinterface/_rinterface.cpython-36m-darwin.so, 2): Library not loaded: @rpath/libicuuc.54.dylib

 Referenced from: /Users/silas/anaconda3/envs/wgcna/lib/python3.6/site-packages/rpy2/rinterface/_rinterface.cpython-36m-darwin.so
  Reason: image not found

and may potentially be resolved by updating the anaconda packages:

https://bitbucket.org/rpy2/rpy2/issues/402/error-importing-rpy2robject-library-not

or uninstalling conda-forge and installing the r-base manually:

Unfortunately we do not use anaconda so I can't be much more help in debugging this issue.
