1. 下載VSCode

1. VSCode下載地址
2. 在mac終端里輸入xcode- select --install命令，根據提示安裝xcode工具。

2. 安裝插件（4個）

1. 打開VScode，點擊應用右側菜單欄
   
2. C/C++（必裝）
   
3. Code Runner（必裝）
   
4. CodeLLDB（代碼調試），不安裝這個插件程序調試時，無法在vscode自帶的終端里輸入參數
   

3. 配置環境

1. 新建文件夾
   
2. 打開文件夾
   
3. 在code下新建001_EvnTest.cpp
   
4. 點擊右上角的小齒輪
   
5. 選擇點擊C/C++：gcc或者C/C++：clang
   
6. 會自動添加launch.json和tasks.json文件，并自動打開launch.json文件
   
7. 配置launch.json和tasks.json文件

• launch.json文件配置

  {"configurations": [{"name": "C/C++: g++ build and debug active file","type": "cppdbg","request": "launch","program": "${fileDirname}/${fileBasenameNoExtension}","args": [],"stopAtEntry": false,"cwd": "${fileDirname}","environment": [],"externalConsole": false,"MIMode": "lldb","preLaunchTask": "C/C++: g++ build active file"}],"version": "2.0.0"
  }
  

• task.json文件配置

  {"tasks": [{"type": "cppbuild","label": "C/C++: g++ build active file","command": "/usr/bin/g++","args": ["-fdiagnostics-color=always","-g","${file}","-o","${fileDirname}/${fileBasenameNoExtension}"],"options": {"cwd": "${fileDirname}"},"problemMatcher": ["$gcc"],"group": "build","detail": "Task generated by Debugger."}],"version": "2.0.0"
  }
  

4. 運行程序

1. 運行程序，點擊Run Code運行程序，程序會在終端中運行
   
2. 調試程序，不要使用右上角的debug，使用左側菜單欄中的調試
   

5. 遇到的問題

1. 如果在運行程序的時候，遇到問題Undefined symbols for architecture x86_64：

   Undefined symbols for architecture x86_64:"_main", referenced from:implicit entry/start for main executable
   ld: symbol(s) not found for architecture x86_64
   clang: error: linker command failed with exit code 1 (use -v to see invocation)
   

   原因：cpp文件的文件名不合規，比如用了特殊符合，空格等。
