我在使用 MinGW 和 VS Code "g++ not recognized as a cmdlet..." 时遇到构建错误

Question

我正在尝试在 VS Code 2019 中设置构建和运行一个 c++ 文件。编辑 tasks.json 文件后出现构建错误。环境变量应该设置为 g++。到目前为止，我一直在关注 this tutorial.

我尝试按照 GitHub 上的问题线程中的建议将 "command" 更改为 "C:\MinGW\bin\g++.exe"。但是，因为我的 c++ 文件不在这个文件路径中，所以当我构建代码时程序无法找到它。 tasks.json 文件的 "command" 部分应该是这样的：

"label": "build calculator adventure",
            "type": "shell",
            "command": "g++",
            "args": [
                "-g",
                "-o",
                "Calculator-Adventure",
                "Calculator Adventure.cpp"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }

"Calculator-Adventure" 部分是我的文件名。预期的输出是用于为我的代码构建和创建 .exe 文件的代码，如教程中所述和 VS 代码文档中所述。

但是，它目前将以下内容输出到终端：

> Executing task: ‪‪g++ -g Calculator Adventure.cpp -o Calculator-Adventure <

g++ : The term 'g++' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

The terminal process terminated with exit code: 1"

好的，我终于想通了。对我有用的是将 git bash shell (C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Git) 的文件路径添加到控制面板中的系统环境变量 (怎么做 here）。确保还将 MinGW bin 文件夹的文件路径添加到环境变量中（32 位安装程序：C:\MinGW\bin）（64 位安装程序：C:/mingw-w64/x86_64-8.1.0-win32-seh-rt_v6-rev0/mingw64/bin) 然后，重新启动 VS Code 并再次构建 (Ctrl+Shift+B)。

这是 .json 文件的最终代码：

c_cpp_properties.json:

    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "windowsSdkVersion": "10.0.17763.0",
            "compilerPath": "C:/mingw-w64/x86_64-8.1.0-win32-seh-rt_v6-rev0/mingw64/bin/g++.exe",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "gcc-x64",
            "browse": {
                "path": [
                    "${workspaceFolder}"
                ],
                "limitSymbolsToIncludedHeaders": true,
                "databaseFilename": ""
            }
        }
    ],
    "version": 4
}

tasks.json:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build calculator adventure",
            "type": "shell",
            "command": "g++",
            "args": [
                "-g",
                "-o",
                "Calculator-Adventure",
                "Calculator Adventure.cpp"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

有关更多信息，请查看 this page. It is a really detailed step-by-step guide for using the MinGW compiler for C++ in VS Code (read it carefully). If you have any other trouble, take a look at this tutorial（问题中链接的相同教程）。希望这对您有所帮助！

注意：在我链接的文档页面中，他们使用 64 位版本的 MinGW。它应该仍然适用于 32 位版本。感谢@drescherjm 发布 VS Code 文档！
