ImportError：无法导入名称start_ipython

Question

I have extracted ipython-1.1.0.tar.gz in /usr/lib/ipython-1.1.0 and have run the following commands to finish the build and installation:

root@my-laptop:/usr/lib/ipython-1.1.0# python setup.py build
root@my-laptop:/usr/lib/ipython-1.1.0# python setup.py install

I am using Python 2.6 and is installed under /usr/bin/python2.6 and have my additional packages under /usr/lib/python2.6/site-packages/

Now, when I am trying to start ipython notebook from shell command, I am getting the following ImportError message:

root@my-laptop:/usr/lib/ipython-1.1.0# ipython notebook
Traceback (most recent call last):
 File "/usr/local/bin/ipython", line 5, in <module>
  from IPython import start_ipython
ImportError: cannot import name start_ipython

When I tried to start the IPython instance as mentioned in README.rst file, I got the following message:

root@my-laptop:/usr/lib/ipython-1.1.0# python -m IPython
/usr/bin/python: IPython is a package and cannot be directly executed

I tried easy_install and pip install

root@my-laptop:/usr/lib/ipython-1.1.0# easy_install ipython
Searching for ipython
Best match: ipython 1.1.0
Adding ipython 1.1.0 to easy-install.pth file

Using /usr/local/lib/python2.6/dist-packages
Processing dependencies for ipython
root@my-laptop:/usr/lib/ipython-1.1.0# pip install ipython
Requirement already satisfied: ipython in /usr/lib/pymodules/python2.6
Installing collected packages: ipython
Successfully installed ipython

But the ImportError problem still remains unresolved. This is not allowing to open the interactive Python.

I found some solution in the below link, but not sure about it:

Answer 1

I just ran into this problem as well. Are we sure the IPython API didn't change? I got something that looks right working with:

import IPython
IPython.Shell.start()

edit: ok, nvmind. There was also another program I installed at the same time that decided to change PYTHONPATH.

Answer 2

This worked for me:

import IPython
IPython.start_ipython()
