为什么我不能启动pymol？

Question

我在试着运行生物技术软件pymol。它找不到cmd.py模块。但是，它位于一个目录中，该目录位于$PYTHONPATH中。

[mzhKU_work] @ modules $ python launch_pymol.py 
Traceback (most recent call last):

    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 $ 

可能的问题是什么？

Answer 1

它尝试导入的模块是_cmd，而不是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，您可以将cmd.py复制到_cmd.py。
