Can't install mmh3 for Python3.7.1 on Win10x64 - visual C++ build tools aren't recognized

Question

I'm trying to install mmh3 (with some other libs) on Python - other libs are installing OK, but mmh3 rises an error:

ERROR: Complete output from command 'c:\python37\python.exe' -u -c 'import setuptools, tokenize;__file__='"'"'C:\\Users\\evgeniy\\AppData\\Local\\Temp\\pip-install-ppmbqvid\\mmh3\\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\evgeniy\AppData\Local\Temp\pip-record-6no3ekq2\install-record.txt' --single-version-externally-managed --compile:

After i got this error at first, i've installed Microsoft Visual C++ Build Tools 15 (v14 was installed too), checked, whether Python has its environment variables and restarted.

After restart and running pip install -r requirements.txt same error fires again. AND, really weird: the paths cited in the error text don't exist, both of them:

• not C:\\Users\\evgeniy\\AppData\\Local\\Temp\\pip-record-6no3ekq2\\install-record.txt
• not C:\\Users\\evgeniy\\AppData\\Local\\Temp\\pip-install-ppmbqvid\\mmh3\\

In the folder named TEMP, which obviously exists, are no leftovers of mmh3 install or logs or anything related.

What should i do to get mmh3 installed?

PS :

• solution under https://www.scivision.dev/python-windows-visual-c-14-required/ doesn't help
• installing Python into default installation directory (AppData/Local/Programs/Python/Python37) doesn't help too

Answer 1

The trick is to install the lib (mmh3 or any other, which makes troubles) from within Visual Studio.

From within means from its own terminal / cmd window , like explained in the step 4 of Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat)
