Error installing Willie irc bot for Python

Question

Trying to install this Python IRC bot called Willie. This is what happens when I run setup.py:

What am I doing wrong? I downloaded the source code from https://github.com/embolalia/willie/releases/tag/v5.3.0 and tried running setup.py in PyCharm.

Answer 1

It should be fairly obvious by the error messages:

** make sure the development packages of libxml2 and libxslt are installed **

You need to have the dev libxml2 and libxslt installed. It appears either you have the wrong versions perhaps, or don't have them installed properly.

Answer 2

I'L'I's answer gives you a hint of where to start searching next, but isn't a useful answer.

After several attempts on my own, I found that to get the lxml library installed, I needed to do the following:

First, download the lxml library from http://www.lfd.uci.edu/~gohlke/pythonlibs/

This is necessary because the PiPy archives (https://pypi.python.org/pypi/lxml/3.4.4) are way out of date, only giving you the option to install for Python 3.2 for the 3+ series, which of course is useless if you're on 3.4. There's also issues if you're using 64-bit. They may be sufficient if you're using 2.7, though.

Then use the instructions here: How do I install a Python package with a .whl file? to install the .whl file.

However that only fixes half the problem. The willie package appears to be broken in other ways (on Windows) because of trying to reference a unix-like /tmp directory (absolute path) instead of the proper Windows Temp directory.

This issue describes the problem, though no fix has yet been made: https://github.com/embolalia/willie/issues/811

It indicates that it's a Windows-specific bug in the installer. To work around that, download the .tar.gz from https://pypi.python.org/pypi/willie/5.3.0

Unpack it. Go to the willie-5.3.0\willie.egg-info directory, and edit the SOURCES.txt file. The fifth line is /tmp/tmpeAhjCF/willie. Delete that line.

Repackage the directory into a .tar.gz archive. Install via pip install .\willie-5.3.0.tar.gz.

Now it's installed, and you're ready for the next round of problems of actually getting it to run on Windows. Since I haven't actually succeeded in doing that yet, that's as far as I can help for right now.
