python - 安装 iPython : "ImportError cannot import name path"?

Question

我正在尝试安装 IPython。我已经运行 pip install ipython[notebook] 没有任何错误，但现在我明白了:

$ ipython notebook
Traceback (most recent call last):
  File "/Users/me/.virtualenvs/.venv/bin/ipython", line 7, in <module>
    from IPython import start_ipython
  File "/Users/me/.virtualenvs/.venv/lib/python2.7/site-packages/IPython/__init__.py", line 48, in <module>
    from .terminal.embed import embed
  File "/Users/me/.virtualenvs/.venv/lib/python2.7/site-packages/IPython/terminal/embed.py", line 16, in <module>
    from IPython.core.interactiveshell import DummyMod
  File "/Users/me/.virtualenvs/.venv/lib/python2.7/site-packages/IPython/core/interactiveshell.py", line 31, in <module>
    from pickleshare import PickleShareDB
  File "/Users/me/.virtualenvs/.venv/lib/python2.7/site-packages/pickleshare.py", line 41, in <module>
    from path import path as Path
ImportError: cannot import name path

如果我尝试在 Python 控制台上运行 import pickleshare 或 from path import path，我也会遇到同样的错误。

我能做些什么来解决这个问题？

看起来这是一个 known issue ，由 path.py 包中的更改引起。恢复到旧版本的 path.py 可以解决这个问题:

sudo pip3 install -I path.py==7.7.1
