在Windows上安装PyGraphViz，Python 2.7 graphviz-2.36

Question

我已经提到链接 ，但仍面临问题:(

我成功地在我的Windows 7上安装了graphviz。现在我想安装pygraphviz。 我下载了pygraphviz zip文件并将其解压缩。 我修改了setup.py并添加了下面的文字。

# Windows
library_path='c:/Program Files (x86)/Graphviz2.36/lib/release/lib'
include_path='C:/Program Files (x86)/Graphviz2.36/include/graphviz'

我还修改了unixcompiler.py。 我删除了该行

compiler = os.path.basename(sysconfig.get_config_var("CC"))

而不是我写的

compiler = 'gcc'

当我尝试安装pygraphviz我得到以下错误:(

一个适合我的简单解决方案：

• 运行pip install graphviz （PS：可能不需要此步骤）
• 从安装的Graphviz： 这里
• 从这里安装pygraphviz的非官方二进制文件
