vs code Mac OS C++ debug 掛起問題

VS Code版本：

Version: 1.41.1
Commit: 26076a4de974ead31f97692a0d32f90d735645c0

VS 插件版本：

ms-vscode.cmake-tools：1.3.0

ms-vscode.cpptools: 0.26.3

編譯工具：

clang --version

Apple LLVM version 10.0.0 (clang-1000.11.45.5)

Target: x86_64-apple-darwin18.7.0

Thread model: posix

lldb --version

Swift-4.2

cmake --version

cmake version 3.16.3

Mac OS 版本

對於如下的launch.json,debug的時候可能會掛起，表現爲點vscode的任何調試相關按鈕都沒反應，打印變量也毫無反應，只能結束調試，CPU在lldb-mi進程上的使用率會超過100%，看日誌是掛在create var上面。日誌是這樣：

1: (2550) <-1035-var-create - * "desc"

        {

            //"program":"/Users/admin/Downloads/trojan-1.14.1/build/trojan",
            "args": [],

                ,"traceResponse": true
                ,"engineLogging": true
            },
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
            ,"miDebuggerPath":"/Users/admin/.vscode/extensions/ms-vscode.cpptools-0.26.3/debugAdapters/lldb/bin/lldb-mi"
        }
    ]
}

解決

辦法是把上面文件的其中一個屬性改成

”MIMode“:"lldb"
