When I attempt to run the Python interpretter within lldb, I'm seeing:
$ lldb
(lldb) script
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "/usr/local/Cellar/python/2.7.14/Frameworks/Python.framework/Versions/2.7/lib/python2.7/copy.py", line 52, in <module>
import weakref
File "/usr/local/Cellar/python/2.7.14/Frameworks/Python.framework/Versions/2.7/lib/python2.7/weakref.py", line 14, in <module>
from _weakref import (
ImportError: cannot import name _remove_dead_weakref
Python Interactive Interpreter. To exit, type 'quit()', 'exit()' or Ctrl-D.
When I inspect what version of Python was launched, Python reports that it should be the Homebrew Python (which is symlinked into this location):
>>> sys.executable
'/usr/local/opt/python/bin/python2.7'
However, asking the Python version returns the version associated with the default system Python installation, e.g.
>>> sys.version_info
sys.version_info(major=2, minor=7, micro=10, releaselevel='final', serial=0)
And, just to confirm, the Python version at the binary path above is indeed different (note the difference in the micro version):
$ /usr/local/opt/python/bin/python2.7 --version
Python 2.7.14
$ /usr/bin/python --version
Python 2.7.10
To make things more confusing, the name _remove_dead_weakref does exist in the _weakref module for my Homebrew Python installation, but not the default system installation:
$ /usr/bin/python -c "import _weakref; print _weakref._remove_dead_weakref"
Traceback (most recent call last):
File "<string>", line 1, in <module>
AttributeError: 'module' object has no attribute '_remove_dead_weakref'
$ /usr/local/opt/python/bin/python2.7 -c "import _weakref; print _weakref._remove_dead_weakref"
<built-in function _remove_dead_weakref>
Any idea what could be causing this apparent cross-talk between my Python installations with LLDB? How can I prevent this?
