# 背景 #

最近刚考完试，有空来回复一下博客上的评论。在回复一条关于克鲁斯卡尔最短路径算法的评论时，为了能够让回复的内容更直观，决定贴上代码的调试信息（代码是用C写的）。我的电脑是MBP，没有安装XCode，只有Visual Studio Code，于是决定使用它来获取一些调试信息，但是我按照网上的教程配置好调试环境后，一直出现**调试进程无法在我打的断点处停下的情况，一闪就过去了。**度娘上面搜了好久也没有结果，最后在[微软的官方教程][Link 1]上找到的端倪，原来这是Mac OS Catalina 10.15的BUG，也就是调试进程能够认到断点的存在，但是程序就直接运行完退出了。如下图所示：

上图中红框表明能够认到断点

上图中，退出代码为0，正常退出，没有在断点处暂停。

# 环境 #

我的设备环境是

>  *  Mac os Catalina 10.15.2
>  *  Visual Studio Code 1.14.1

# 解决办法 #

## 新的插件 ##

解决的办法也很简单，在VSCode的插件中心搜索`CodeLLB`的插件安装，重启VSCode即可。

## 配置步骤 ##

Step1：按住键盘上的⌘ \+⇧\+P，搜索`Debug: Open launch.json`

或者点击左边的小虫子，选择`create a launch.json file`。

Step2：选择LLDB

Step3：编写基础配置文件

{ 
        // Use IntelliSense to learn about possible attributes.
        // Hover to view descriptions of existing attributes.
        // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
        "version": "0.2.0",
        "configurations": [
            { 
                "type": "lldb",
                "request": "launch",
                "name": "Debug",
                "program": "${workspaceFolder}/${fileBasenameNoExtension}.out",
                "args": [],
                "cwd": "${workspaceFolder}"
            }
        ]

Step4 ：保存配置后⌘\+⇧\+B编译后即可断点调试

# 配置文件文件分享 #

最后分享一下我的配置文件，希望能帮助到大家
