How to solve error while installing Django channels?

Question

Django

pip version - 9.0.3, Windows
I install via pip install channels, but at the time of twisted installation an error occurs:
Command "D:\ZadaniaOtAndreia\SOCIAL_NETWORK\V2\tutorial-50\venv\Scripts\python.exe -u -c "import setuptools, tokenize;__file__='C:\\Users\\3C8A~1\\AppData\\Local\\Temp\\pip-build-6kxur0lv\\twisted\\setup.py';f=getattr(tokenize, ' open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec') )" install --record C:\Users\3C8A~1\AppData\Local\Temp\pip-gwpoeerd-record\install-record.txt --single-version-externally-managed --compile --install-headers D :\ZadaniaOtAndreia\SOCIAL_NETWORK\V2\tutorial-50\venv\include\site\python3.6\twisted" failed with error code 1 in C:\Users\3C8A~1\AppData\Local\Temp\pip-build-6kxur0lv\twisted\
What to do? Has anyone else experienced this or knows/know how to fix it?

Answer 2

"Databases. A textbook for universities" - A. D. Homonenko, V. M. Tsygankov, M. G. Maltsev
We read the section on database design, there is not much there. If after reading you still do not understand what to do, then you are not given.

Answer 3

Read about normal forms. Take classic mysql, postgresql, mssql.
Each entity into a separate table, make tables - links between entities.
To put it simply, yes. I'm doing a similar project myself.

Answer 4

I advise you to design everything in WorkBench.

Answer 5

I also advise you to use the MySQL WorkBench program for database design.
