进口海运中的吡喃

Question

我已经将seaborn升级为0.9.0，pycharm似乎没什么印象。

在命令行上工作的脚本无法通过：

 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>

任何小费都会得到赏识。

如果您有一个与标准库模块/包同名的自定义模块/包，例如PYTHONPATH，这可能是由于cmd冲突造成的。

诀窍是PyCharm和IntelliJ与Python一起向PYTHONPATH添加项目根、内容根和源根，因此脚本可能在终端中正确工作，但在PYTHONPATH中执行时失败。

若要禁用内容和源根的此行为，请转到专用运行配置和取消选中选项。

• 将内容根添加到PYTHONPATH
• 向PYTHONPATH添加源根

或右击项目树->标记目录中的相应目录，将->取消标记为源根。

内容根可以在设置\项目.\项目结构中进行管理。
