这里有新手：如何在Windows 7中将补丁应用于python包的源代码？

Question

我正在尝试在Windows 7 x64下为Python 3.5 x86安装Pygraphviz 尝试安装后，我收到此处显示的错误

https://github.com/Kagami/pygraphviz/commit/fe442dc16accb629c3feaf157af75f67ccabbd6e

在该线程的底部有一个对必须应用于pygraphviz包的补丁的引用，然后我想我将不得不从源代码安装它

我的问题是：如何在Windows中使用补丁？

更新：我已经下载了Windows补丁和补丁文件 我把它们放在与源包相同的文件夹中 - 见图片

现在我需要为此找到正确的命令行开关 干运行（补丁--Dry-run＆lt; fixpygraphviz.patch ）给我这个错误

Perhaps you should have used the -p or --strip option?

File to patch:

Answer 1

patch -px -i patchfilename

其中x表示要从补丁文件中指示的路径跳过多少级别的文件夹。在我的情况下，它是p1，这意味着补丁应该寻找“文件夹/文件名”，而不是补丁文件中指示的“文件夹/文件夹/文件名”。
