[Python-modules-team] Bug#815081: ipython3: Does not work if inside virtualenv

[Joel Cross]

Package: ipython3
Version: 2.4.1-1
Severity: normal
Tags: patch

Dear Maintainer,

The `ipython3` command is not runnable from within a virtualenv if ipython is
not installed locally.

To reproduce:
* Create an empty Python 3 virtualenv using the `virtualenv` command, ensuring
that --no-site-packages is passed if necessary.
* Run `ipython3`

The following traceback appears:

Traceback (most recent call last):
  File "/usr/bin/ipython3", line 4, in <module>
    from IPython import start_ipython
ImportError: No module named 'IPython'

Changing the first line of the script to #!/usr/bin/python3 fixes the problem.
