rpy2 install problems on debian

Question

I have tried every install method I can think of to install RPy2 on our debian server and I get the same message regardless. I have installed and used it successfully on my mac. Is there something I may be missing?

start

Processing rpy2
Running setup.py -q bdist_egg --dist-dir /opt/rpy2/egg-dist-tmp-oft2ko

returned an empty string.


returned an empty string.

Thank you for the help

Answer 1

Please try

sudo apt-get install python-rpy2

(or use whichever packaging frontend you prefer) as the package exists within the distribution.

Answer 2

If you compile R with

./configure --enable-R-shlib, then R is installed in /usr/local/lib/R

So you can add this lines to .bashrc, for you and root user

export R_HOME=/usr/local/lib/R
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$R_HOME/lib

Then you can install from pip or build from tarball

Answer 3

As pointed in rpy2 installation on Ubuntu, sometimes a missing python-dev (python-devel in RHEL) may cause these issues. You can fix by either

    sudo apt-get install python-dev

or

    sudo yum install python-devel

Or other OS specific instruction for installing python-dev[el]
