我正在尝试运行生物技术软件 pymol。它找不到cmd.py模块。但是，它位于 $PYTHONPATH 中的目录中。

[mzhKU_work] @ modules $ python launch_pymol.py 
Traceback (most recent call last):
  File "launch_pymol.py", line 32, in <module>
    import pymol
  File "/Users/mzhKU_work/software/pymol/modules/pymol/__init__.py", line 521, in <module>
    import pymol._cmd
ImportError: No module named _cmd

[mzhKU_work] @ modules $

可能是什么问题呢？

它试图导入的模块是_cmd，不是cmd。

您的问题看起来像是库中的错误，您可以尝试将其报告给开发人员。

作为临时解决方案，您可以复制cmd.py到_cmd.py.
