ipdb is triggering ImportError

ipdb is triggering an import error for me when I run my Django site locally. I'm working on Python 2.7 and within a virtual environment.

which ipdb shows the path (/usr/local/bin/ipdb), as does which ipython, which surprised me since I thought it should show my venv path (but shouldn't it work if it's global, anyway?). So I tried pip install --target=/path/to/venv ipdb and now it shows up in pip freeze (which it didn't before) but still gives me an import error.

which pip gives /Users/myname/.virtualenvs/myenv/bin/pip/

My path: /Users/myname/.virtualenvs/myenv/bin:/Users/myname/.venvburrito/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/myname/bin:/usr/local/bin

Sys.path: '/Users/myname/Dropbox/myenv', '/Users/myname/.venvburrito/lib/python2.7/site-packages/pip-1.4.1-py2.7.egg', '/Users/myname/.venvburrito/lib/python2.7/site-packages', '/Users/myname/.venvburrito/lib/python2.7/site-packages/setuptools-8.2-py2.7.egg', '/Users/myname/.virtualenvs/myenv/lib/python27.zip', '/Users/myname/.virtualenvs/myenv/lib/python2.7', '/Users/myname/.virtualenvs/myenv/lib/python2.7/plat-darwin', '/Users/myname/.virtualenvs/myenv/lib/python2.7/plat-mac', '/Users/myname/.virtualenvs/myenv/lib/python2.7/plat-mac/lib-scriptpackages', '/Users/myname/.virtualenvs/myenv/Extras/lib/python', '/Users/myname/.virtualenvs/myenv/lib/python2.7/lib-tk', '/Users/myname/.virtualenvs/myenv/lib/python2.7/lib-old', '/Users/myname/.virtualenvs/myenv/lib/python2.7/lib-dynload', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/Users/myname/.virtualenvs/myenv/lib/python2.7/site-packages']

If I run ipdb from the terminal, it works fine. I've tried restarting my terminal.

Solution

  • I was using virtualenv-burrito. Deleting my venv, updating burrito (virtualenv-burrito upgrade) and making a new virtual environment fixed the problem.
