python2.7 sysconfig broken under virtualenv · Issue #118 · pypa/virtualenv (original) (raw)

This is preventing numpy from installing correctly:

$ virtualenv --version
1.6

>>> import sysconfig
>>> sysconfig.get_config_vars()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/sysconfig.py", line 444, in get_config_vars
    _init_posix(_CONFIG_VARS)
  File "/usr/lib/python2.7/sysconfig.py", line 298, in _init_posix
    raise IOError(msg)
IOError: invalid Python installation: unable to open /home/bgolemon/software/sqlalchemy/local/lib/python2.7/config/Makefile (No such file or directory)

>>> sysconfig._get_makefile_filename()
'/home/bgolemon/software/sqlalchemy/local/lib/python2.7/config/Makefile'

Quick fix:
mkdir local
ln -s ../lib local/lib
