UnicodeDecodeError while installing for Python3.3

Just came across this

Happens for pymc==2.3.2 thru pymc==2.3.6, for Python 3.4 and 3.3. Python 2.7 installs ok.

[fonnesbeck]

Can you post the code that generates this error? I'd like to try to replicate it here.

[hjwp]

Just pip install pymc (in a Python 3.3/3.4 virtualenv, or use pip-3.4, or whatever is available in your env to pip install for a particular python version...)

[fonnesbeck]

I can't replicate this with Anaconda Python 3.3 in a virtualenv:

[hjwp]

I'm on Ubuntu. I think it's fairly consistent, not something to do with my setup. I can repro it in a minimal dockerfile:

FROM ubuntu:trusty
RUN apt-get update
RUN apt-get install -y python3-dev python3-pip 
RUN apt-get install -y python3-numpy python3-matplotlib
RUN pip3 install pymc

Here's the full output from the minimal repro run: http://pastebin.com/9SEww4CT

when I install pymc in windows platform use “pip install pymc", it will report this error:

 File "c:\Python34\lib\site-packages\numpy\f2py\crackfortran.py", line 336, in readfortrancode
    l=fin.readline()
  File "c:\Python34\lib\fileinput.py", line 363, in readline
    self._buffer = self._file.readlines(self._bufsize)
UnicodeDecodeError: 'gbk' codec can't decode byte 0xa1 in position 6844: illegal multibyte sequence

[hjwp]

I fixed it by setting the LANG environment variable(s):

LANG=en_US.UTF-8
LANGUAGE=en_US:en
LC_ALL=en_US.UTF-8

But it might be nice to get it working without that...

[fonnesbeck]

We do have a .cfg file for Debian installs. Would it work to put these there?

Ran into the same issue myself on a Mac (10.11) using Python 3.5. hjwp's environment variable fix worked for me to successfully install. https://github.com/pymc-devs/pymc/issues/62#issuecomment-151760213

#62 (comment) did't work for me. I got the same error: UnicodeDecodeError: 'gbk' codec can't decode byte 0xa1 in position 6844: illegal multibyte sequence
