我正在关注这个post使一个ipython规则所有的virtualenvs。IPython导入失败和一般的python sys.path
从我的理解，这篇文章的主要思想是，当在virtualenv中，ipython找不到它的模块。
(a-virtualenv)[email protected]:~$ 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
要解决这个问题，我补充这对我的/ usr/bin中/ IPython中
import sys
if "/usr/lib/python2.7/dist-packages" not in sys.path:
sys.path.append("/usr/lib/python2.7/dist-packages")
这招适用于巴尔萨泽。但对我来说，我得到这个
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
我想，也许我应该在/usr/bin/ipython加/usr/lib/python2.7/dist-packages/IPython/external到sys.path为好。我得到的是对IPython/__init__py线43发生
Traceback (most recent call last):
File "/usr/bin/ipython", line 18, 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
这个错误，但在第46行
前一个发生怎样才能让IPython中使用的virtualenv工作？
如何将
/usr/lib/python2.7/dist-packages/IPython/external添加到sys.path导致新的错误？我应该阅读什么来更好地理解python导入路径？
谢谢！
PS： 正常IPython中的sys.path
['',

你可以发布你看到如果你运行'import sys;在你的* normal * python中打印sys.path'？ （即你安装IPython的那个） – 2012-07-20 07:43:51
现在在添加'/usr/lib/pymodules/python2.7'之后，ipython似乎很有用。 – zjk 2012-07-20 08:07:29
好吧，你似乎已经解决了你的问题（基本上，通过检查你的路径，然后搞清楚你实际需要添加什么）。你应该把它作为这个问题的答案。 – 2012-07-20 08:09:21
