cm.error('Hey dude.. this is it')

嘿伙计们，我有两个问题4你好吗？

1：最后一行cm.error（'X'）给我一个运行时错误

2：类声明仅适用于我第一次运行它，当我想获得刷新转换信息时我应该再次运行脚本

请帮助duuuudes。

最好的问候。

Answer 1

最后一行总是给你一个错误（有关更多信息，请参阅此链接 http://download.autodesk.com/global/docs/maya2013/en_us/CommandsPython/error.html）

Answer 2

不是使用headsUpMessage()而是使用更强大的东西，例如声明自己的错误类。这个link解释了很多关于这个主题的内容。顺便说一下，你实际上并没有使用pymel，因此标记你的问题是不准确的。 maya.cmds只是用python包裹着。要使用pymel，你需要像这样导入：

from pymel.core import *

pymel中的运行时错误
