Pip install problem
From ACL@NCU
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')
