我正在關注這個post使一個ipython規則所有的virtualenvs。IPython導入失敗和一般的python sys.path
從我的理解，這篇文章的主要思想是，當在virtualenv中，ipython找不到它的模塊。
(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
要解決這個問題，我補充這對我的/ 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")
這招適用於巴爾薩澤。但對我來說，我得到這個
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>

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，也許我應該在/usr/bin/ipython加/usr/lib/python2.7/dist-packages/IPython/external到sys.path爲好。我得到的是對IPython/__init__py線43發生
Traceback (most recent call last):

from IPython.external.path import path
ImportError: cannot import name path
這個錯誤，但在第46行
前一個發生怎樣才能讓IPython中使用的virtualenv工作？
如何將
/usr/lib/python2.7/dist-packages/IPython/external添加到sys.path導致新的錯誤？我應該閱讀什麼來更好地理解python導入路徑？
謝謝！
PS： 正常IPython中的sys.path

你可以發佈你看到如果你運行'import sys;在你的* normal * python中打印sys.path'？ （即你安裝IPython的那個） – 2012-07-20 07:43:51
現在在添加'/usr/lib/pymodules/python2.7'之後，ipython似乎很有用。 – zjk 2012-07-20 08:07:29
好吧，你似乎已經解決了你的問題（基本上，通過檢查你的路徑，然後搞清楚你實際需要添加什麼）。你應該把它作爲這個問題的答案。 – 2012-07-20 08:09:21
