Hello everyone,
I posted this on github and got no answers, I found a similar posting
here from January
(https://mail.python.org/pipermail/ironpython-users/2015-January/017391.html)
where no solution is mentioned so here I am.
I get an error when I try to install a package via pip.
I use ironpython 2.7.5 and tested on several PC, all windows.
Copied from https://github.com/IronLanguages/main/issues/1203
I'm new to Python so this might be something I'm doing wrong, but I'm
having the following problem:
I installed iron Python 2.7.5, and then installed pip with|ipy.exe
-X:Frames -m ensurepip|
So far everything works fine, but when I tried to install packages it
didn't work.
Any help is appreciated, following is a detailed description.
I installed Ironpython on WinXP for the first time, then ensurepip, and
tried getting pyvisa without success. Then went to a basic pip package
as shown in the release info but it's not working.
Executing the line|ipy.exe -X:Frames -m pip install html5lib|gives me an
error as follows:
| File "C:\Archivos de programa\IronPython
2.7\lib\site-packages\pip\_vendor\requests\packages\urllib3\packages\ssl_match_hostname\_implementation.py",
line 88, in match_hostname
for key, value in sub:
ValueError: too many values to unpack
|
After digging a bit the problem is that the following code
|sub = ('txt1','txt2')
for key,value in sub:
print key,value
|
gives the error
|File "<stdin>", line 1, in <module>
ValueError: too many values to unpack
|
I don't understand why this happens, any ideas?
After this was detected, if I modify _implementation.py to work around
this error, I get a new error which I don't get. The log file follows:

It seems the server is reporting the wrong hostname?
Anyone knows what's happening here?
