在Windows 10上安装扭曲的错误。INCLUDE环境变量为空

Question

I have installed python 3.4.4 on my windows machine and trying to install twisted library on my machine.

>>>python
Python 3.4.4 (v3.4.4:737efcadf5a6, Dec 20 2015, 20:20:57) [MSC v.1600 64 bit (AMD64)] on win32

Here is my output of pip freeze currently

>>>pip freeze
constantly==15.1.0
incremental==16.10.1
requests==2.12.4
zope.interface==4.3.3

When I am trying to install twisted via pip I am getting this error.

Answer 1

Maybe this would work for you.

pip install wheel
pip install D:\Documents\Downlaods\Twisted-17.1.0-cp27-cp27m-win32.whl

The 27 is corresponding to python 2.7
