Pymel OpenMaya依赖？

Question

我在哪里可以获得pymel的Open依赖？我没有在文档的任何地方看到这个陈述

Traceback (most recent call last):
 File "test.py", line 1, in <module>

File "/Users/kromah/Documents/Developer/Github/pymel/pymel/versions.py", line 13, in <module> from maya.OpenMaya import MGlobal as _MGlobal

[ImportError：没有名为OpenMaya的模块]
