error: command 'C:\\mingw-w64\\x86_64-4.9.0-win32-seh-rt_v3-rev2\\mingw64\\bin\\

Answer 1

cannot find -lpython27

python27.lib is not on your LIBRARY_PATH. It's hard to say why or provide more info because you didn't explain how you got to this point - commands run, Python version installed, etc.

In any case, I strongly recommend that you just use the binary installers. See these existing answers:
