Cannot install sqlalchemy #89

I am trying to pip install sqlalchemy but it fails with:

ERROR: Command "/var/mobile/Containers/Data/Application/415FE8A3-9150-4DC4-BB74-03B29A13F6B5/Library/bin/python3 /var/mobile/Containers/Data/Application/415FE8A3-9150-4DC4-BB74-03B29A13F6B5/Library/lib/python3.7/site-packages/pip/_vendor/pep517/_in_process.py get_requires_for_build_wheel /private/var/mobile/Containers/Data/Application/415FE8A3-9150-4DC4-BB74-03B29A13F6B5/tmp/tmprd_ol6vi" failed with error code 1 in /private/var/mobile/Containers/Data/Application/415FE8A3-9150-4DC4-BB74-03B29A13F6B5/tmp/pip-install-h7gd8kjl/sqlalchemy`

I have not tested this, but the sqlalchemy documentation says that you can issue the command setenv DISABLE_SQLALCHEMY_CEXT 1 before running pip install and it won't even try to compile the C extensions.

I just tried as you suggest and after issuing the command and redoing the pip install sqlalchemy, got:

Hi, on the latest TestFlight version, !pip install sqlalchemy gives a lot of warnings because it first tries to install the C extensions and fails, but ultimately installs the package (without the C extensions).
