我有点坚持弄清楚为什么这不起作用。我没有对代码做任何事情，所以我有点好奇为什么它不再起作用。任何帮助表示赞赏。这是我得到的错误：

    [ERROR] gamemodes/harborrp/gamemode/data.lua:59: attempt to index global 'GameDatabase' (a nil value)

以下是它所指的位置：

第 58 行：

        DB.Log(err)

GameDatabase 为零。当 GameDatabase 仅声明为服务器端时，您可能正在尝试在客户端运行此代码。您可以if SERVER then检查共享代码以使其仅在服务器端运行。
