Hi there, I'm currently struggling with virtualenv and python2.6. I've a work related project which sadly uses the old python2.6 interpreter and a bunch of python dependencies specified in a requirements.txt. Because most of the dependencies aren't available in NixOS (and even more not in the correct version), I want to use virtualenv with pip to set up a dev environment.
Unfortunately, I can't create a virtual environment with python2.6: [jascha@loshi:~]$ mkvirtualenv foobar -p /nix/store/ymysni3zc4y2khppj4b3vvlxbkwqvdgk-python-2.6.9/bin/python2.6 Running virtualenv with interpreter /nix/store/ymysni3zc4y2khppj4b3vvlxbkwqvdgk-python-2.6.9/bin/python2.6 Traceback (most recent call last): File "/nix/store/4s9dqqfg28zp3cm62nsli610nni3xwy5-python2.7-virtualenv-1.11.4/lib/python2.7/site-packages/virtualenv.py", line 2335, in <module> main() File "/nix/store/4s9dqqfg28zp3cm62nsli610nni3xwy5-python2.7-virtualenv-1.11.4/lib/python2.7/site-packages/virtualenv.py", line 824, in main symlink=options.symlink) File "/nix/store/4s9dqqfg28zp3cm62nsli610nni3xwy5-python2.7-virtualenv-1.11.4/lib/python2.7/site-packages/virtualenv.py", line 984, in create_environment site_packages=site_packages, clear=clear, symlink=symlink)) File "/nix/store/4s9dqqfg28zp3cm62nsli610nni3xwy5-python2.7-virtualenv-1.11.4/lib/python2.7/site-packages/virtualenv.py", line 1151, in install_python fix_lib64(lib_dir, symlink) File "/nix/store/4s9dqqfg28zp3cm62nsli610nni3xwy5-python2.7-virtualenv-1.11.4/lib/python2.7/site-packages/virtualenv.py", line 1543, in fix_lib64 if [p for p in distutils.sysconfig.get_config_vars().values() File "/nix/store/c5kna2kla5nf02kllzkd50bws58qp59r-python2.7-distutils.cfg/lib/python2.7/site-packages/distutils/sysconfig.py", line 453, in get_config_vars func() File "/nix/store/c5kna2kla5nf02kllzkd50bws58qp59r-python2.7-distutils.cfg/lib/python2.7/site-packages/distutils/sysconfig.py", line 397, in _init_posix from _sysconfigdata import build_time_vars ImportError: No module named _sysconfigdata Of course, creating a virtual environment with python2.7 works without problems. It also work with python2.6 on debian systems. What I already know: - "mkvirtualenv" (virtualenvwrapper) isn't the problem. I tried plain virtualenv as well - In the example above I used myEnvFun for python2.6. However, installing python2.6 via "nix-env -i" doesn't solve the problem - I can import the needed module interactively in a python2.7 shell - I cannot import it in a python2.6 shell. However, this seems to be normal (can't import it with python2.6 on debian systems as well) Any suggestions? or is there an easier way to set up a dev environment with python2.6 and quite old python deps? I've no idea how to debug this problem. I guess it has something to do with PYTHONPATH or something like that?
