I get an error when fetching requirments

Command "c:\users\vali\appdata\local\programs\python\python37-32\python.exe -u -c "import setuptools, tokenize;__file__='C:\\Users\\Vali\\AppData\\Local\\Temp\\pip-install-scgbaab1\\greenlet\\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\Vali\AppData\Local\Temp\pip-record-ib7f2f8v\install-record.txt --single-version-externally-managed --compile" failed with error code 1 in C:\Users\Vali\AppData\Local\Temp\pip-install-scgbaab1\greenlet\

Looks like an error with greenlet. Quite understandable that they won't be supporting 3.7 quite yet due to how new it is.
I'll update the readme, thank you for reporting this.
