开机自检，将一个ipython规则的所有虚拟NVS
在我的理解中，这篇帖子的主要思想是，在virtualenv上，ipython找不到那个模块。
(a-virtualenv ) me@pc:~$ipython
跟踪后退(mostrecentcalllast ) :
File '/usr/jldlm/ipython '，line 19，in
from ipython.frontend.terminal.ipappimportlaunch _ new _ instance
importerror : nomodulenamedipython.frontend.terminal.IP app
要解决此问题，请将其添加到我的/usr/jldlm/ipython中
导入系统
if '/usr/lib/python 2.7/dist-packages ' not in sys.path :
sys.path.append (/usr/lib/python 2.7/dist-packages ) )
这个招式适用于Balthazar。 但是，就我而言，我得到了这个

我也认为应该在/usr/jldlm/ipython中添加/usr/lib/python 2.7/dist-packages/ipython/external去sys.path .

importerror : cannotimportnamepath
此错误发生在IPython/__ init__py的第43行，但最后发生在第46行。
如何使ipython与virtualenv一起工作？
将/usr/lib/python 2.7/dist-packages/ipython/external添加到sys.path中是否会出现新错误？
我应该读什么才能更好地理解python的导入路径？
谢谢你！
