无法调试lua - Githubissues

constly commented 3 months ago

我按readme中的说明，把launch.json中的配置为:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "lua",
            "request": "launch",
            "name": "Debug",
            "luaexe": "${workspaceFolder}/bin/msvc/debug/ant.exe",
            "luaVersion": "lua-latest",
            "path": null,
            "cpath": null,
            "console": "integratedTerminal",
            "stopOnEntry": true,
            "outputCapture": [],
            "program": "test/simple/main.lua",
            "arg": []
        }
    ]
}

在vscode中以调试方式启动时没反应，输出为:

PS F:\ant\ant>  f:; cd 'f:\ant\ant'; & 'F:/ant/ant/bin/msvc/debug/ant.exe' '-e' 'dofile[[c:/Users/Administrator/.vscode/extensions/actboy168.lua-debug-2.0.10-win32-x64/script/launch.lua]];DBG[[17344/lua-latest]]' 'test/simple/main.lua' 
PS F:\ant\ant>

看起来没启动成功，程序直接退出了。我打开任务管理器，可以看到有lua-debug.exe。之前是可以调试的，不知道那次更新后就不行了。

要更新调试器。vscode 的那个更新了没？ @actboy168

@constly 我测试是没问题的，你是不是没更新调试器。

昨天晚上卸载重装了Lua Debug插件，不得行，不过今天早上来引擎的demo项目可以调试了（可能是重启了电脑）。

现在我这里自己的项目以及vaststars依然不能调试， vaststars调试报错为:

PS G:\ant\github\vaststars>  & 'G:/ant/github/vaststars/bin/msvc/debug/ant.exe' '-e' 'dofile[[c:/Users/username/.vscode/extensions/actboy168.lua-debug-2.0.10-win32-x64/script/launch.lua]];DBG[[38296/lua-latest]]' 'startup/main.lua'
Service 1 error: /engine/firmware/ltask_service.lua:1: attempt to index a nil value
stack traceback:
        /engine/firmware/ltask_service.lua:1: in main chunk
PS G:\ant\github\vaststars>

vaststars的launch.json为:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "lua",
            "request": "launch",
            "name": "Debug",
            "luaexe": "${workspaceFolder}/bin/msvc/debug/ant.exe",
            "luaVersion": "lua-latest",
            "path": null,
            "cpath": null,
            "console": "integratedTerminal",
            "stopOnEntry": true,
            "outputCapture": [],
            "program": "startup/main.lua",
            "arg": []
        }
    ]
}

深感认同，这个报错我调试时也一直出现。即使用最新的Lua Debug也不行跟踪了一下发现 ant/engine/firmware/debugger.lua 运行时有一个path一直获取的是空。 @constly 要不你也看下你的是不是也这样。

local function dofile(filename)
    local f = assert(io.open(filename))
    local str = f:read "a"
    f:close()
    return assert(load(str, "=(debugger.lua)"))(filename)
end

local path = os.getenv "LUA_DEBUG_PATH"
if path then  --此处path为nil，获取不到环境变量值。
    return dofile(path)
        : attach {}
end

继续跟踪到C:\Users\abc\.vscode\extensions\actboy168.lua-debug-2.0.10-win32-x64\script\debugger.lua 第148行附近，添加打印

    local isWindows = package.config:sub(1, 1) == "\\"
    if isWindows then
        assert(package.loadlib(luadebug, 'init'))(cfg.luaapi)
    end

    ---@type LuaDebug
    dbg.rdebug = assert(package.loadlib(luadebug, 'luaopen_luadebug'))()
    if not os.getenv "LUA_DEBUG_PATH" then
    print("set path:", selfsource)    --添加打印
        dbg.rdebug.setenv("LUA_DEBUG_PATH", selfsource)
    print("get path:", os.getenv("LUA_DEBUG_PATH"))   --添加打印
    print("java home path:", os.getenv("JAVA_HOME"))  --添加打印
    else 
    print("pre set:", os.getenv("LUA_DEBUG_PATH"))
    end

打印结果是：

set path:       c:/Users/abc/.vscode/extensions/actboy168.lua-debug-2.0.10-win32-x64/script/debugger.lua
get path:       nil
java home path: D:\Program Files\Java\jdk-19
