Question

"g++"未被识别为内部或外部命令、可执行程序或批处理文件。

6

我正在尝试使用C++编译器在VScode中进行设置，按照这个教程进行操作：链接。

但是我遇到了问题（通过使用Code Runner运行代码）：

“g++”不被识别为内部或外部命令、可操作的程序或批处理文件。链接如果我使用调试选项运行，我会遇到这个问题： preLaunchTask“build & run file”以退出代码1终止。链接这是我的“c_cpp_properties.json”文件。

        }
      ],
      "preLaunchTask": "build & debug file"
    }
  ]
}

这是我的“tasks.json”文件。

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "build & debug file",
      "type": "shell",

        "kind": "build",
        "isDefault": true
      }

    {
      "label": "build & run file",
      "type": "shell",
      "command": "g++",
      "args": [
        "-o",
        "${fileBasenameNoExtension}",
        "${file}"
      ],
      "group": {
        "kind": "build",
        "isDefault": true
      }
    }
  ]
}

我只想学习C++，在网上尝试了很多方法几天了，但仍然无法解决。请帮忙。谢谢。

可能是重复问题：['g++' is not recognized as an internal or external command, operable program or batch file] (https://dev59.com/UVkT5IYBdhLWcg3wZusA)。 - Ken White

关于 "command": "g++"，你可能需要包含完整的位置（包括目录），除非你确定包含它的目录实际上已经在你的标准路径中。 - paxdiablo

Ken White，那篇帖子对我没有帮助。 - S.Xu

这个回答解决了你的问题吗？"g++" is not recognized as an internal or external command, MinGW - Donald Duck
