I am a complete newbie at Python. I wanted to try to see if Pyomo (a Python package for mathematical modeling) could work under IronPython because all my code for generating the data needed for Pyomo is in C\#.

I installed IronPython 2.7.5, then tried as an administrator the advice found in http://blog.ironpython.net/2014/12/pip-in-ironpython-275.html\#disqus\_thread on how to run "pip" for IronPython. I used the exact example they gave (installing html5lib):

ipy -X:Frames -m ensure pip

ipy -X:Frames -m pip install html5lib

The first line worked, and I see in the Lib/site-packages directory a folder called pip-6.1.1-py2.7.egg with lots of python code in it.

For the second line, I received the error:

Unhandled exception:

Traceback (most recent call last):

File "C:\\Program Files (x86)\\IronPython 2.7\\Lib\\runpy.py", line 170, in run\_module

File "C:\\Program Files (x86)\\IronPython 2.7\\Lib\\runpy.py", line 111, in \_get\_module\_details

ImportError: No module named urllib; 'pip' is a package and cannot be directly executed

At this point, I'm stuck. Any help would be appreciated.

Just in case this helps, printing out the sys.version gives:

2.7.5 (IronPython 2.7.5 (2.7.5.0) on .NET 4.0.30319.34209 (32-bit))

I encountered the same problem. It seems that IronPython can't deal with more recent versions of pip. What I did was:

remove all traces from pip and setuptools from IronPython's Lib\\site-packages folder

run from a commandline: ipy.exe -X:Frames -m ensurepip

this installed an old version of pip, one that IronPython understands. Verify this by checking that a folder pip-1.5.6.dist-info appears in IronPython's Lib/site-packages

Moral of the story; don't upgrade to a newer pip version when using IronPython
