这是我在尝试安装“playhaven”插件时在我的Corona模拟器输出上看到的内容。我不知道如何摆脱这个问题。

        Build: 2013.1202 Runtime error ?:0: attempt to call field 'request' (a nil value) stack traceback:

        ?: in main chunk

如果你想查看我的** build.settings 文件，因为在我将插件集成到 build.settings **文件后，我收到了上面显示的错误。

settings =

        orientation =
        {
                default = "portrait",
                supported = { "portrait" },
        },

                },
        },

                        CFBundleIconFiles = {
