我的 C++ 程序無法在 Visual Studio 代碼上編譯

Question

我第一次嘗試使用 Visual Studio Code，但我的 C++ 無法編譯。

我已經將 mingw 的 bin 和 bash.exe 從 MSYS2 添加到我的 PATH。 我的所有代碼都在同一個目錄中，直接來自微軟的指南https://code.visualstudio.com/docs/cpp/config-mingw （我確實改變了我的路徑）。 我的所有文件也都在同一目錄中。

我已經包含了文件

你好世界.cpp：

#include <iostream>


using namespace std;

int main()
{
   cout << "Hello World";
}

任務.json：

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build hello world",
            "type": "shell",
            "command": "g++",
            "args": [
                "-g",
                "-o",
                "helloworld",
                "helloworld.cpp"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

c_cpp_properties.json：

{
    "configurations": [
        {
            "name": "Win32",
            "defines": [
                "_DEBUG",
                "UNICODE"
            ],
            "compilerPath": "C:\\Mingw-w64\\mingw32\\bin\\g++.exe",
            "intelliSenseMode": "gcc-x64",
            "browse": {
                "path": [
                    "${workspaceFolder}"
                ],
                "limitSymbolsToIncludedHeaders": true,
                "databaseFilename": ""
            }
        }
    ],
    "version": 4
}

啟動.json：

{
    "version": "0.2.0",
     "configurations": [
         {
             "name": "(gdb) Launch",
             "type": "cppdbg",
             "request": "launch",
             "program": "${workspaceFolder}/helloworld.exe",
             "args": [],
             "stopAtEntry": true,
             "cwd": "${workspaceFolder}",
             "environment": [],
             "externalConsole": false,
             "MIMode": "gdb",
             "miDebuggerPath": "C:\\Mingw-w64\\mingw32\\bin\\gdb.exe",
             "setupCommands": [
                 {
                     "description": "Enable pretty-printing for gdb",
                     "text": "-enable-pretty-printing",
                     "ignoreFailures": true
                 }
             ]
         }
     ]
 }

該文件不會構建，我不斷收到相同的錯誤消息：

g++.exe：錯誤：helloworld.cpp：沒有那個文件或目錄 g++.exe：致命錯誤：沒有輸入文件編譯終止。 終端進程以退出代碼終止：1

似乎編譯器無法定位源文件，更新tasks.json以編譯具有完整路徑的程序，

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build hello world",
            "type": "shell",
            "command": "g++",
            "args": [
                "-g",
                "${file}",//Just
                "-o",//edit
                "${workspaceFolder}\\${fileBasenameNoExtension}"//these
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

這里${file}給出了帶有擴展名 (.cpp) 的文件的完整路徑， ${workspaceFolder}和${fileBasenameNoExtension}也幾乎不言自明。

 That eventually worked after I exited the shell and re-opened it

{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
    {
        "label": "echo",
        "type": "shell",
        "command": "g++",
        "args": [
            "-g", "main.cpp"
        ],
        "group": {
            "kind": "build",
            "isDefault": true
        }
    }
]
}
