VSCode中安装以下插件

• ms-python.python：python调试
• ms-python.vscode-pylance：代码跳转（非必要）

配置launch.json

在当前工作区，按此路径.vscode\launch.json新建launch.json文件，并配置以下参数：

• type：python
• request：launch
• console：integratedTerminal
• justMyCode：设置为true，表示只调试自己的python脚本
• program：配置为当前文件即可，${file}
• “args”：配置python脚本所需要传入的参数。

}

设置断点

打开需要调试的 python脚本，在行号处，右键。选择“添加断点”即可

启动调试

下面以调试EDK2的构建脚本build.py为例。

• 点击左侧工具栏的运行和调试按钮，调出其控制面板
• 在控制面板右上角，选择调试当前python脚本，随后点击“▷”按钮，启动调试

首次启动，会出现如下错误：未找到某些module。

发生异常: ModuleNotFoundError
No module named 'AutoGen'File "E:\JasonEDK2\BaseTools\Source\Python\build\build.py", line 34, in <module>from AutoGen.PlatformAutoGen import PlatformAutoGen
ModuleNotFoundError: No module named 'AutoGen'

这是由于未跑edksetup.bat初始化编译环境导致的。

此时点击右上角的调试按钮 “▢”中止此次调试，在下图中的“终端”对话框中执行 ”edksetup.bat“，随后再次启动调试即可。
