conda incompatible with local installations? #448
Description
I normally use pip to handle all the packages in my system:
$ pip-2.7 install numpy --user
$ /usr/bin/python2.7 -c "import numpy; print numpy.version.version"
1.8.0
so they get installed in ~/.local/python2.7/site-packages. Then I wanted to give conda a try, so I did this:
$ ./Miniconda[...].sh
# No PYTHONPATH defined
# Prepend .anaconda to PATH: yes
$ [new shell] conda update conda
$ conda install numpy==1.7.1
$ ./.anaconda/bin/python2.7 -c "import numpy; print numpy.version.version"
1.8.0
I still cannot reach the 1.7.1 version installed with conda. If I remove the .local one, I can use the conda version again.
$ ./.anaconda/bin/python2.7 -c "import sys; from pprint import pprint as p; p(sys.path)"

It seems the path is not correctly handled.
>>> import sys
>>> sys.path.append(sys.path.pop(-2))
>>> p(sys.path)
