默认情况下，MacOS和Mac OS X中包含SQLite。所以我认为您是在问在VSCode中的哪里添加您的-lsqlite3链接参数，对吗？如果是，则有一个隐藏文件夹.vscode，里面是一个tasks.json：

打开task.json：

{
"tasks": [
    {
        "type": "cppbuild",
        "label": "C/C++: clang build active file",
        "command": "/usr/bin/clang",
        "args": [
            "-fcolor-diagnostics",
            "-fansi-escape-codes",
            "-g",
            "${file}",
            "-o",
            "${fileDirname}/${fileBasenameNoExtension}"
        ],
        "options": {
            "cwd": "${fileDirname}"
        },
        "problemMatcher": [
            "$gcc"
        ],
        "group": {
            "kind": "build",
            "isDefault": true
        },
        "detail": "Task generated by Debugger."
    },
    {
        "type": "cppbuild",
        "label": "C/C++: clang build active file",
        "command": "/usr/bin/clang",
        "args": [
            "-fcolor-diagnostics",
            "-fansi-escape-codes",
            "-g",
            "-l",
            "sqlite3",
            "${file}",
            "-o",
            "${fileDirname}/${fileBasenameNoExtension}"
        ],
        "options": {
            "cwd": "${fileDirname}"
        },
        "problemMatcher": [
            "$gcc"
        ],
        "group": "build",
        "detail": "compiler: /usr/bin/clang"
    }
],
"version": "2.0.0"
}

您找到我添加的sqlite3命令了吗？就这样。
现在，如果您构建并运行main.c文件，VSCode将成功编译和链接，您就可以进行调试了。
