Я следую за этимсообщение сделать так, чтобы один ipython управлял всеми virtualenvs.

Из того, что я понимаю, основная идея поста заключается в том, что, когда в virtualenv, ipython не может найти свои модули.

(a-virtualenv)me@pc:~$ ipython
Traceback (most recent call last):
  File "/usr/bin/ipython", line 19, in <module>
    from IPython.frontend.terminal.ipapp import launch_new_instance
ImportError: No module named IPython.frontend.terminal.ipapp

Чтобы обойти это, я добавляю это в мой / usr / bin / ipython

import sys
if "/usr/lib/python2.7/dist-packages" not in sys.path:
    sys.path.append("/usr/lib/python2.7/dist-packages")

Этот трюк работает на Бальтазара. Но в моем случае я получаю это

Traceback (most recent call last):
  File "/usr/bin/ipython", line 18, in <module>
    from IPython.frontend.terminal.ipapp import launch_new_instance
  File "/usr/lib/python2.7/dist-packages/IPython/__init__.py", line 46, in <module>
    from .frontend.terminal.embed import embed
  File "/usr/lib/python2.7/dist-packages/IPython/frontend/terminal/embed.py", line 37, in <module>
    from IPython.frontend.terminal.ipapp import load_default_config
  File "/usr/lib/python2.7/dist-packages/IPython/frontend/terminal/ipapp.py", line 38, in <module>
    from IPython.core.completer import IPCompleter
  File "/usr/lib/python2.7/dist-packages/IPython/core/completer.py", line 84, in <module>
    from IPython.utils import generics
  File "/usr/lib/python2.7/dist-packages/IPython/utils/generics.py", line 19, in <module>
    from IPython.external.simplegeneric import generic
  File "/usr/lib/python2.7/dist-packages/IPython/external/simplegeneric/__init__.py", line 4, in <module>
    from _simplegeneric import *
ImportError: No module named _simplegeneric

Я думал, может быть, я должен добавить/usr/lib/python2.7/dist-packages/IPython/external вsys.path в/usr/bin/ipython также. Что я получаю

Traceback (most recent call last):
  File "/usr/bin/ipython", line 18, in <module>
    from IPython.frontend.terminal.ipapp import launch_new_instance
  File "/usr/lib/python2.7/dist-packages/IPython/__init__.py", line 43, in <module>
    from .config.loader import Config
  File "/usr/lib/python2.7/dist-packages/IPython/config/loader.py", line 27, in <module>
    from IPython.utils.path import filefind, get_ipython_dir
  File "/usr/lib/python2.7/dist-packages/IPython/utils/path.py", line 24, in <module>
    from IPython.utils.process import system
  File "/usr/lib/python2.7/dist-packages/IPython/utils/process.py", line 27, in <module>
    from ._process_posix import _find_cmd, system, getoutput, arg_split
  File "/usr/lib/python2.7/dist-packages/IPython/utils/_process_posix.py", line 27, in <module>
    from IPython.utils import text
  File "/usr/lib/python2.7/dist-packages/IPython/utils/text.py", line 27, in <module>
    from IPython.external.path import path
ImportError: cannot import name path

Эта ошибка произошла в строке 43IPython/__init__py, но предыдущий произошел в строке 46.

How can I make ipython work with virtualenv?

How can adding /usr/lib/python2.7/dist-packages/IPython/external to sys.path resulting a new error?

What should I read to get a better understanding of python import path?

Спасибо!

PS: нормальный IPython sys.path
