Question

所以我正在使用Visual Studio Code来构建和运行一个简单的C ++程序。我使用task.json处理编译：（基于此：How to compile C++ code with VS Code and cl

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "Build Test",
            "type": "shell",
            "command": "cl",
            "args": [
                "/MDd",
                "/W4",
                "/EHsc",
                "/ZI",
                "/std:c++11",
                "/Od",
                "/Fe:${workspaceFolder}/Debug/test.exe",
                "/Fd:${workspaceFolder}/Debug/",
                "/Fo:${workspaceFolder}/Debug/",
                "main.cpp"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        },
        {
            "label": "Build Release",
            "type": "shell",
            "command": "cl",
            "args": [
                "/MD",
                "/W4",
                "/EHsc",
                "/std:c++11",
                "/O2",
                "/Fe:${workspaceFolder}/Release/test.exe",
                "/Fd:${workspaceFolder}/Release/",
                "/Fo:${workspaceFolder}/Release/",
                "main.cpp"
            ]
        }
    ]
}

但是当我尝试构建时，会得到以下输出：

 Executing task: cl /MDd /W4 /EHsc /ZI /std:c++11 /Od "/Fe:G:\My Drive\Semester 3\CS 341\Project\Project 2/Debug/test.exe" "/Fd:G:\My Drive\Semester 3\CS 341\Project\Project 2/Debug/" "/Fo:G:\My Drive\Semester 3\CS 341\Project\Project 2/Debug/" main.cpp <

'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

我会注意到，我确实以以下方式更改了设置：

"terminal.integrated.shellArgs.windows": [
        "/k",
        "C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Community\\VC\\Auxiliary\\Build\\vcvars64.bat"
    ],
"terminal.integrated.shell.windows": "C:\\Windows\\System32\\cmd.exe"

我认为这是“ C：\ Program”的来源。我只想在Visual Studio中构建和执行C ++程序，因此将不胜感激。

编辑： 因此，我决定将C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Community\\VC\\Auxiliary\\Build添加到PATH变量中，然后将设置更改为：

"terminal.integrated.shellArgs.windows": [
        "/k",
        "vcvars64.bat",
    ],
 "terminal.integrated.shell.windows": "C:\\Windows\\System32\\cmd.exe"

导致错误变为：

> Executing task: cl /MDd /W4 /EHsc /ZI /std:c++11 /Od "/Fe:G:\My Drive\Semester 3\CS 341\Project\Project 2/Debug/test.exe" "/Fd:G:\My Drive\Semester 3\CS 341\Project\Project 2/Debug/" "/Fo:G:\My Drive\Semester 3\CS 341\Project\Project 2/Debug/" main.cpp <

The syntax of the command is incorrect.

Answer 1

在这种情况下，可以使用转义字符（即插入符号（^）来解决空格和括号的问题。使用提到的字符，settings.json中的相关行将如下所示：

"terminal.integrated.shellArgs.windows": [
    "/k",
    "C:\\Program^ Files^ ^(x86^)\\Microsoft^ Visual^ Studio\\2017\\Community\\VC\\Auxiliary\\Build\\vcvars64.bat"
],
"terminal.integrated.shell.windows": "C:\\Windows\\System32\\cmd.exe"

此方法的问题与将vcvars64.bat的路径添加到PATH变量时遇到的问题相同，即Visual Studio Code将附加这些值执行任务时，从"command"中以"args"和tasks.json为前缀的/d和/c中的"terminal.integrated.shellArgs.windows"中的vcvars64.bat。结果是cmd.exe将获得提及的值作为参数，而不是[ERROR:vcvarsall.bat]。出现带有{ // See https://go.microsoft.com/fwlink/?LinkId=733558 // for the documentation about the tasks.json format "version": "2.0.0", "options": { "shell": { "executable": "C:\\Windows\\System32\\cmd.exe", "args": [ "/d", "/c", "C:\\Program^ Files^ ^(x86^)\\Microsoft^ Visual^ Studio\\2017\\Community\\VC\\Auxiliary\\Build\\vcvars64.bat", "&&" ] } }, "tasks": [ { "label": "Build Test", "type": "shell", "command": "cl", "args": [ "/MDd", "/W4", "/EHsc", "/ZI", "/std:c++11", "/Od", "/Fe:${workspaceFolder}/Debug/test.exe", "/Fd:${workspaceFolder}/Debug/", "/Fo:${workspaceFolder}/Debug/", "main.cpp" ], "group": { "kind": "build", "isDefault": true } }, { "label": "Build Release", "type": "shell", "command": "cl", "args": [ "/MD", "/W4", "/EHsc", "/std:c++11", "/O2", "/Fe:${workspaceFolder}/Release/test.exe", "/Fd:${workspaceFolder}/Release/", "/Fo:${workspaceFolder}/Release/", "main.cpp" ] } ] }标签的错误是因为拒绝将参数附加到错误的位置。

您可以通过指定一个带有适当任务参数的外壳来解决此问题，如下所示：

"terminal.integrated.shellArgs.windows"

另一种方法是将cmd.exe保留为空，即不要将任何参数传递给settings.json中的tasks.json，然后按如下所示更改{ // See https://go.microsoft.com/fwlink/?LinkId=733558 // for the documentation about the tasks.json format "version": "2.0.0", "options": { "env": { "build": "C:\\Program^ Files^ ^(x86^)\\Microsoft^ Visual^ Studio\\2017\\Community\\VC\\Auxiliary\\Build\\vcvars64.bat && cl" } }, "tasks": [ { "label": "Build Test", "type": "shell", "command": "%build%", "args": [ "/MDd", "/W4", "/EHsc", "/ZI", "/std:c++11", "/Od", "/Fe:${workspaceFolder}/Debug/test.exe", "/Fd:${workspaceFolder}/Debug/", "/Fo:${workspaceFolder}/Debug/", "main.cpp" ], "group": { "kind": "build", "isDefault": true } }, { "label": "Build Release", "type": "shell", "command": "%build%", "args": [ "/MD", "/W4", "/EHsc", "/std:c++11", "/O2", "/Fe:${workspaceFolder}/Release/test.exe", "/Fd:${workspaceFolder}/Release/", "/Fo:${workspaceFolder}/Release/", "main.cpp" ] } ] }：< / p>

vcvars64.bat

如果从Visual Studio的开发人员命令提示符启动Visual Studio代码，则可以省略在每次构建之前调用cmd /d /c "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\Tools\VsDevCmd.bat" && start /b code的必要性。为了方便起见，您可以使用以下控件创建快捷方式：

SELECT LISTAGG(output_author_name, ', ') WITHIN GROUP (ORDER BY 
output_title_name),output_title_name 
FROM tablename;

这将使开发人员命令提示符保持打开状态，可以根据需要将其关闭。

Answer 2

文件夹名称中的空格会破坏提示，因此请确保在 settings.json 文件中将路径“Program Files”更新为简单的“PROGRA~1”

例如当我改变时

"java.home": "C:\\Program Files\\JDK\\11" to
"java.home": "C:\\PROGRA~1\\JDK\\11"

它开始工作了
