每当我在控制台中输入错误或出错时，都会出现以下消息：

Traceback (most recent call last):
  File "/usr/lib/python3.3/site.py", line 629, in <module>
    main()

  File "/usr/lib/python3.3/site.py", line 614, in main
    known_paths = addusersitepackages(known_paths)

    user_site = getusersitepackages()

  File "/usr/lib/python3.3/site.py", line 260, in getusersitepackages
    user_base = getuserbase() # this will also set USER_BASE

  File "/usr/lib/python3.3/site.py", line 250, in getuserbase
    USER_BASE = get_config_var('userbase')

    return get_config_vars().get(name)

    from _sysconfigdata_m import *

   ImportError: No module named '_sysconfigdata_m'

我同时使用Anaconda安装了Python 2.7和3.3。我想知道这是否正常还是python 2.7和3.3之间存在冲突
