Pip install problem

pip install cffi

But vcvarsall.bat exists on the system. This is because python 2.7 does not support MS Visual Studio ver > 8.0. To fix it: modifing the Lib\distutils\msvc9compiler.py can make it support vs 10.0 change 304 line

VERSION = get_build_version()

to

VERSION = 10.0

and add,

ld_args.append('/MANIFESTFILE:' + temp_manifest) #line 684
ld_args.append('/manifest')
