我在Windows 8中安装了GraphViz 2.32,并将C:\ Program Files(x86)\ Graphviz2.32\bin添加到System PATH变量中.仍然pydot无法找到它的可执行文件.

Traceback (most recent call last):
  File "<pyshell#26>", line 1, in <module>
    graph.write_png('example1_graph.png')
  File "build\bdist.win32\egg\pydot.py", line 1809, in <lambda>
    lambda path, f=frmt, prog=self.prog : self.write(path, format=f, prog=prog))
  File "build\bdist.win32\egg\pydot.py", line 1911, in write
    dot_fd.write(self.create(prog, format))
  File "build\bdist.win32\egg\pydot.py", line 1953, in create
    'GraphViz\'s executables not found' )
InvocationException: GraphViz's executables not found
