I'm using Ubuntu 10.10 and there's only on ipython installed. (There's also only one python available, but I got an older version with <a href="https://launchpad.net/~fkrull/+archive/deadsnakes" rel="nofollow">the deadsnakes ppa</a>.)

To get ipython2.5, I installed ipython from your virtualenv:

<pre><code>virtualenv --python=/usr/bin/python2.5 project_name
source project_name/bin/activate
pip install ipython
</code></pre>

Then the ipython version should match the python passed into virtualenv with <code>--python</code>.

You can just:

or

blocks|key|3267252|text|实际上，您可以使用您喜欢的python版本运行ipython：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3267253|python2.7+ipython
python3+ipython|code-block|syntax|javascript|3267254|这对我来说是最简单的解决方案，避免了一次性试验的虚拟环境设置。|3267255|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Actually you can run the ipython with the python version you like:

<pre><code>python2.7 ipython
python3 ipython
</code></pre>

This is easiest solution for me and avoids virtual env setup for one-shot trials.

blocks|key|45877|text|我发现指定使用哪个python版本的最简单方法是使用该版本显式调用ipython脚本。为此，您可能需要知道ipython脚本的路径，您可以通过运行which+ipython找到该脚本。然后简单地运行python+<path-to-ipython>来启动ipython。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|45878|entityMap^0|21|D|2R|O|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

I find the simplest way to specify which python version to use is to explicitly call the ipython script using that version. To do this, you may need to know the path to the ipython script, which you can find by running <code>which ipython</code>. Then simply run <code>python &lt;path-to-ipython&gt;</code> to start ipython.

I am running an Ubuntu 8.10, using Python 2.5 out of the box. This is fine from the system point of view, but I need Python2.4 since I dev on Zope / Plone.

Well, installing python2.4 is no challenge, but I can't find a (clean) way to make iPython use it : no option in the man nor in the config file.

Before, there was a ipython2.4 package but it is deprecated.
