pip install Pweave hits a configparser.DuplicateOptionError #25

Closed g2boojum closed 7 years ago

g2boojum commented 9 years ago

I'm not sure what has changed, but pip is now failing to install the Pweave scripts. I've included the traceback below, but apparently configparser lower-cases keys (I found the error mentioned at http://www.gilesorr.com/blog/python-3-configparser.html), and so Ptangle and ptangle look the same to it and they collide. Running "python setup.py install" works just fine, so presumably the bug is in pip, not in Pweave. That said, pip is failing to correctly install Pweave....

configparser.DuplicateOptionError: While reading from '<???>' [line  4]: option 'ptangle' in section 'console_scripts' already exists

I ran this using a fresh python 3.4 virtualenv:

$ pip list
pip (7.1.2)
Pweave (0.23)
setuptools (18.2)
wheel (0.24.0)

Pweave does apparently get installed, albeit without the scripts, despite the pip failure.

There seems to be a fix coming to pip: https://github.com/pypa/pip/pull/3324

Latest pip works fine. Amend the comment in the docs to no longer warn against using pip?

ndvanforeest commented 7 years ago

While trying to install the latest pweave (0.30.1) I just ran into this message too. To solve it, I deleted the pweave directory:

nicky@chuck:/usr/local/lib/python3.5/dist-packages$ sudo rm -rf Pweave-0.2*

and I also removes Pweave and Ptangle in /usr/local/bin. After this, pip3 install worked without problem.

Might the pip3 install files for Pweave not be completely correct?

BTW: thanks for the great work.

pip fails uinstalling 0.25, but uninstalling 0.30 will work. Uppercase version of pweave and ptangle were removed from 0.30 to prevent this error.
