Greetings To Python-list,

I'm trying to install Python package:

   mitmproxy (https://mitmproxy.org/)

on Windows XP SP3.

I'm a complete Python newbie. Not planning to do any Python programming 
at this time. Just trying to get package mitmproxy working (or at least 
the mitmdump component, since "There is no interactive user interface on 
Windows." per:

   http://docs.mitmproxy.org/en/stable/install.html

* * *
* * *

I have installed Python that announces itself on the Python command line 
as:

   Python 2.7.11 (v2.7.11:6d1b6a68f775, Dec  5 2015, 20:32:19) [MSC 
v.1500 32 bit (Intel)] on win32

* * *
* * *

I'm using the following command in a Win XP cmd.exe shell (not the 
Python shell) to install mitmproxy:

   pip install mitmproxy

The first install attempt failed, ending with some diagnostics displayed 
in the Win XP cmd.exe shell window:

   C:\Documents and Settings\SteveP>pip install mitmproxy

   You are using pip version 7.1.2, however version 8.0.0 is available.
   You should consider upgrading via the 'python -m pip 
install --upgrade pip' command.

I  upgraded pip to version 8.0.0:

I tried again to install mitmproxy, and the installation got a little 
further, but failed again on a similar error, on a different file 
(watchdog-0.8.3.tar.gz instead of pyperclip-1.5.26.zip):

In both failure cases, it looks to me like there is a bug in the pip 
logic, that is using a *nix forward slash "/" instead of a double 
backslash "\\" before the file name "make.bat".

The upgrade to pip-8.0.0 fixed the first occurrence of the problem, but 
not the second occurrence.

I note the warning lines displayed at the start of the second install 
attempt:

   C:\Documents and Settings\SteveP>pip install mitmproxy
   e:\a p p s\python27\lib\site-packages\pip\pep425tags.py:89: 
RuntimeWarning: Config variable 'Py_DEBUG' is unset, Python ABI tag may

     warn=(impl == 'cp')):
   e:\a p p s\python27\lib\site-packages\pip\pep425tags.py:93: 
RuntimeWarning: Config variable 'WITH_PYMALLOC' is unset, Python ABI tag

     warn=(impl == 'cp')):
   e:\a p p s\python27\lib\site-packages\pip\pep425tags.py:99: 
RuntimeWarning: Config variable 'Py_UNICODE_SIZE' is unset, Python ABI 
tag may be incorrect
     sys.version_info < (3, 3))) \

and wonder if they are relevant to the failure.
