我试图在Windows 7上构建pygraphviz但有问题，请参阅下面的回溯1。目前我正在考虑改为mingw gcc编译。但是也看到使用的编译器应该与我的发行版中使用的相同 - Python（x，y）。
我很清楚疼痛others have had with this issue。但似乎无法找到我确切的问题。
我确实拥有并且可以轻松获得Christoph Gohlke's Unofficial Windows Binaries for Python Extension Packages的工作版本。我尝试构建的原因是我认为这可能是我遇到问题的原因described here（我知道我可能会抓住这里的稻草，并欢迎直接对此可能是愚蠢的。）
我接下来应该采取哪些调试步骤？
请注意。我之前将msvc9compiler.py文件更新到下面（以修复this problem - 请参阅追溯2）：
def library_dir_option(self, dir): # FIXED VERSION
if ' ' in dir and not dir.startswith('"'):
dir = '"%s"' % dir
return "/LIBPATH:" + dir
