【问题描述】：

我正在创建一个将游戏 api 暴露给嵌入式 python 解释器的游戏扩展，我在 PyMethodDef 中收到 C2133 数组未知大小错误：

static PyMethodDef pyTTPlayerMethods[] = 
"Get_Player_Name", pyTTGet_Player_Name, METH_VARARGS, "Returns the nickname of a client.",
"Get_Player_Type", pyTTGet_Player_Type, METH_VARARGS, "TODO: Returns the player type of a client.",
"Get_Bandwidth", pyTTGet_Bandwidth, METH_VARARGS, "Returns a player's bandwidth.",
"Get_Ping", pyTTGet_Ping, METH_VARARGS, "Returns the ping of a client.",
"Get_Kbits", pyTTGet_Kbits, METH_VARARGS, "Return kbits of a client.",
"Get_Ip", pyTTGet_Ip_Address, METH_VARARGS, "Returns the IP of a client.",
"Get_Port", pyTTGet_Ip_Port, METH_VARARGS, "Returns the port of a client.",
"Get_Team", pyTTGet_Team, METH_VARARGS, "Returns the team ID of a client.",
"Get_Translated_Team", pyTTGet_Translated_Team, METH_VARARGS, "Returns the team name of a client (GDI, NOD).",
"Change_Team", pyTTChange_Player_Team, METH_VARARGS, "Changes the team of a client.",
"Change_Team2", pyTTChange_Player_Team2, METH_VARARGS, "Changes the team of a client without killing respawning the player.",
"Get_Kills", pyTTGet_Kills, METH_VARARGS, "Returns the kill count of a client.",
"Get_Deaths", pyTTGet_Deaths, METH_VARARGS, "Returns the death count of a client.",
"Get_KD", pyTTGet_KillDeath_Ratio, METH_VARARGS, "Returns the KD ratio of a client.",
"Get_Rank", pyTTGet_Rank, METH_VARARGS, "Returns the rank of a client.",
"Set_Rung", pyTTSet_Rung, METH_VARARGS, "Sets the rung of a client.",
"Set_Ladder_Points", pyTTSet_Ladder_Points, METH_VARARGS, "Returns the rank of a client.",
"Get_Score", pyTTGet_Score, METH_VARARGS, "Returns the score of a client.",
"Set_Score", pyTTSet_Score, METH_VARARGS, "Sets the score of a client.",
"Get_Money", pyTTGet_Money, METH_VARARGS, "Returns the amount of money a client has.",
"Set_Money", pyTTSet_Money, METH_VARARGS, "Sets the amount of money a client has.",
"Refill", pyTTGrant_Refill, METH_VARARGS, "Replenishes a client's health and ammo.",
"Change_Character", pyTTChange_Character, METH_VARARGS, "Changes a client's character.",
"Toggle_Fly_Mode", pyTTToggle_Fly_Mode, METH_VARARGS, "Toggles a client's flying mode.",
"Is_Stealth", pyTTIs_Stealth, METH_VARARGS, "Returns a client's stealth status.",
NULL, NULL, 0, NULL
;

编译插件时，我得到这个结果：

1>------ Build started: Project: PythonTT, Configuration: Release SSGM Win32 ------

第一个错误是因为我在 PyObject 中选择了错误的调用，但我不知道如何更正最后一个错误（C2133）；有什么建议吗？

【问题讨论】：

减少数组并尝试找到一个最小的例子来说明问题。很可能在文本墙上只有一个逗号或不应该的东西。代码通常应该是正确的。

代码对我来说也不错。摆脱其他编译器错误 - 可能是其中一个扰乱了编译器并导致了 C2133。

@Voo , Nick 我错误地将列表声明为头文件中的其他内容，不过感谢您的帮助

【参考方案1】：

您可以尝试使用选项 /Ze 进行编译，将一个未调整大小的数组声明为成员。 http://msdn.microsoft.com/en-us/library/0k0w269d%28v=vs.71%29
