python3和RO包以及DS9

Question

如何獲取RO包在Python 3中的工作原理？我設法得到它在Python 2.7的工作，但是當我手動安裝爲python3 setup.py install，然後做import RO.DS9我得到這個：

Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "/usr/local/lib/python3.4/dist-packages/RO-3.6.9-py3.4.egg/RO/DS9.py", line 160, in <module> 
    import RO.OS 
    File "/usr/local/lib/python3.4/dist-packages/RO-3.6.9-py3.4.egg/RO/OS/__init__.py", line 7, in <module> 
    from .OSUtil import * 
    File "/usr/local/lib/python3.4/dist-packages/RO-3.6.9-py3.4.egg/RO/OS/OSUtil.py", line 31, in <module> 
    import RO.SeqUtil 
    File "/usr/local/lib/python3.4/dist-packages/RO-3.6.9-py3.4.egg/RO/SeqUtil.py", line 33, in <module> 
    import UserString 
ImportError: No module named 'UserString' 
>>> exit() 

Answer 1

在Python 3，UserString is part of the collections module。

正如您在the RO page上看到的，該庫僅支持Python 2.6和2.7。
