Cannot compile esp-at

[AppdigEng]

I have tried every which way I can think of but still cannot get the esp-at to compile. I've followed the readme file to the letter but something always breaks.

This is my latest output.

The following Python requirements are not satisfied:
cryptography>=2.1.4
pyparsing>=2.0.3,<2.4.0
The recommended way to install a packages is via "pacman". Please run "pacman -Ss <package_name>" for searching the package database and if found then "pacman -S mingw-w64-i686-python2-<package_name>" for installing it.
NOTE: You may need to run "pacman -Syu" if your package database is older and run twice if the previous run updated "pacman" itself.
Please read https://github.com/msys2/msys2/wiki/Using-packages for further information about using "pacman"
WARNING: The cryptography package have dependencies on system packages so please make sure you run "pacman -Syu" followed by "pacman -S mingw-w64-i686-python2-cryptography".
Alternatively, you can run "C:/msys32/mingw32/bin/python.exe -m pip install --user -r C:/msys32/home/Jeff/esp/esp-idf/requirements.txt" for resolving the issue.
make: *** [C:/msys32/home/Jeff/esp/esp-idf/make/project.mk:501: check_python_dependencies] Error 1


So I try to intall the python requirements and get this..
$ python -m pip install --user -r c:/msys32/home/Jeff/esp/esp-idf/requirements.txt

Complete output (45 lines):

No working compiler found, or bogus compiler options passed to
the compiler from Python's standard "distutils" module. See
the error messages above. Likely, the problem is not related
to CFFI but generic to the setup.py of any Python package that
tries to compile C code. (Hints: on OS/X 10.8, for errors about
-mno-fused-madd see http://stackoverflow.com/questions/22313407/
Otherwise, see https://wiki.python.org/moin/CompLangPython or
the IRC channel #python on irc.freenode.net.)

Trying to continue anyway. If you are trying to install CFFI from
a build done in a different context, you can ignore this warning.

I don't know what to do next.
