pycharm - 在pycharm中导入seaborn

Question

我已经将 seaborn 升级到 0.9.0 而 pycharm 似乎不为所动。

在命令行上运行的脚本无法继续过去:

 import seaborn as sns

抛出以下内容:

Traceback (most recent call last):
  File "/Applications/PyCharm CE.app/Contents/helpers/pydev/pydevd.py", line 1664, in <module>
    main()
  File "/Applications/PyCharm CE.app/Contents/helpers/pydev/pydevd.py", line 1658, in main
    globals = debugger.run(setup['file'], None, None, is_module)

    class Pdb(bdb.Bdb, cmd.Cmd):
AttributeError: module 'cmd' has no attribute 'Cmd'

感谢任何提示。

这可能是由于 PYTHONPATH 冲突导致的，如果你有一个自定义模块/包与标准库模块/包同名，例如命令。

技巧是 PyCharm 和带有 Python 插件的 IntelliJ 将项目根、内容根和源根添加到 PYTHONPATH 因此脚本可能在终端中正常运行但在 IDE 中执行时失败。

要为内容和源根禁用此行为，请转到专用运行配置并取消选中选项

• 将内容根添加到 PYTHONPATH
• 将源代码添加到 PYTHONPATH

或者右击项目树中的相应目录-> Mark Directory as -> Unmark as Sources Root。

可以在设置 | 中管理内容根目录项目... |项目结构。
