Here is the environment:
- OS:windows 10
- Django:2.0rc
- Python:3.6
- pip:10.0.0
- visual studio community 2017
And the error message:
running build_ext
building 'twisted.test.raiser' extension
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual
C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

I have already installed the build tools following the link description but it still doesn't work. If someone has solved it, please tell me how to fixed it.

Download twisted from this link.
Downloading Twisted‑18.4.0‑cp36‑cp36m‑win32.whl worked for me because I'm using Python 3.6. Download the version according to the python that you use.
After you download Twisted from the given link, open up a cmd where the file is located and run pip install Twisted‑18.4.0‑cp36‑cp36m‑win32.whl. pip will install Twisted from this file.
If you're doing it in a virtualenv, activate the virtualenv and install Twisted after that in the same process.
After that, you'll be able to install channels or whatever.
