@qwcode: What do you make of this error? Is there something wrong with the setuptools wheel, or pkg_resources, or one of the other packages?

Original comment by qwcode (Bitbucket: qwcode, GitHub: qwcode):

---

the associated virtualenv issue is pypa/virtualenv#524

@pmoore suspects it's a bug with the assertion in _zipinfo_name. I'm not sure at the moment.

this virtualenv release is very different in that it's adding 2 whl/zip files (for setuptools and pip) to the pythonpath, and then using pip to do the pip/setuptools install from wheels

Original comment by qwcode (Bitbucket: qwcode, GitHub: qwcode):

---

it's only an issue when virtualenv is installed using easy_install (or python setup.py install)

Original comment by qwcode (Bitbucket: qwcode, GitHub: qwcode):

---

to recreate easily outside of virtualenv, just add a pip or setuptools wheel file to your pythonpath, and then import pkg_resources

EDITED: this is not generally true, it's only true if you add the pip or setuptools wheel as installed in the virtualenv Egg

Original comment by qwcode (Bitbucket: qwcode, GitHub: qwcode):

what's happening:

• it's trying to add the setuptools whl/zip to the working set
• it checking for 'PKG-INFO' in the zip
• it ends up constructing the zip path using the virtualenv egg root (which contains the setuptools wheel), and not the setuptools whl file as the root

still trying to sort out where exactly it goes wrong.

Original comment by qwcode (Bitbucket: qwcode, GitHub: qwcode):

---

ok, I have a fix locally, that seems ok.

the problematic code is here: https://bitbucket.org/pypa/setuptools/src/735202ca6848d58bc59022f85cde10af64a61a7e/pkg_resources.py?at=default#cl-1383

this is what incorrectly constructs the path using the wrong root.

my fix is to override _setup_prefix in the ZipProvider to just pass.

If I can figure out PRs in bitbucket, maybe I'll log it.

Original comment by qwcode (Bitbucket: qwcode, GitHub: qwcode):

---

overriding _setup_prefix to just pass is too aggressive.
trying to sort out what the best fix would be that's not just a hack, which means actually understanding pkg_resources internals...

Is this the same issue I'm having? It's caused by installing virtualenv with easy_install instead of pip, but gives a different traceback:

I have also observed the same with the following packages.

python3.3,
pip-1.5,
ditribute-0.7.3,
virtualenv-1.11.

I have posted the error in Askubuntu and launchpad as well the links are given below.

Merged in qwcode/setuptools/zip_path (pull request #32)

convert "find_in_zip" into "find_eggs_in_zip" to prevent it from walking whl files. Fixes #129

@qwcode, @jaraco

Thanks for fixing this.

I don't mean to rush you, but can you estimate how long before this fix is on pypi? I need to weigh up whether it's worth me writing workarounds into our deployment scripts or if I should just wait until this is released.

Expect a release today. I'm on travel or I would have released already.

No probs. Thanks again.
