Why does pip install winshell not work on Python v

问题:

Install winshell with pip:

C:\Users\jonc>pip install winshell
Downloading/unpacking winshell
  Downloading winshell-0.6.zip
  Running setup.py (path:C:\Users\jonc\AppData\Local\Temp\pip_build_Jonc\winshell\setup.py) egg_info for package winshell

Installing collected packages: winshell
  Running setup.py install for winshell

Successfully installed winshell
Cleaning up...

Try and import it:

C:\Users\jonc>python
Python 3.4.2 (v3.4.2:ab2c023a9432, Oct  6 2014, 22:16:31) [MSC v.1600 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import winshell
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python34\lib\site-packages\winshell.py", line 30, in <module>
    import win32con
ImportError: No module named 'win32con'

Why does this fail?

Pip version is as follows:

C:\Users\jonc>pip -V
pip 1.5.6 from C:\Python34\lib\site-packages (python 3.4)

回答1:

you will need to install pywin32 to get the missing file.
it must be installed separately (i.e. it cannot be installed with pip). for more information see this post.
