Pip doesn't install Twisted on Windows

Use this link. http://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted.

Its a repository for unofficial modules, but works every time for me. Use win32 version.

I had the same problem too but I solved it as follow: Open the Anaconda Prompt as administrator (For Windows10: open cortana/write Anaconda Prompt/choose Run as Administrator)

You should go to the path of Anaconda, for me was like:

C:\WINDOWS\system32>cd ..
C:\WINDOWS>cd..
C:\>cd  ProgramData
C:\ProgramData>cd Anaconda3
C:\ProgramData>Anaconda3>

Then you should run the following command

C:\ProgramData>Anaconda3>conda install -c anaconda twisted

At some point it asks

Proceed ([y]/n)?

type y. Now twisted is installed.
