使用Python 3.3的virtualenv中的IPython Notebook

我已经设置了我的Ubuntu 12.04系统,这样我就可以使用Python 2.7或Python 3.3创建virtualenv,并运行IPython Notebook.问题是,我不知道我对我的系统做了什么让这成为可能.我试图帮助其他人以相同的方式设置他们的系统,我不确定我缺少什么包.

在我的系统上,我可以运行以下命令,以便在virtualenv中运行IPython Notebook:

~$ mkdir test_ipython3.3
~$ cd test_ipython3.3
~/test_ipython3.3$ virtualenv -p python3.3 venv
~/test_ipython3.3$ source venv/bin/activate
(venv)~/test_ipython3.3$ pip install ipython[all]==1.1.0

我可以使用相同的命令集virtualenv -p python2.7 venv,并且除了运行Python 2.7之外,它具有几乎相同的环境.

我试图在virtualbox设置上安装12.04,这样我也可以成功运行这些命令,但是我一直都在失败.在virtualbox中构建一个干净的Ubuntu 12.04计算机后,我执行以下操作:

# Update machine:
sudo apt-get update
sudo apt-get dist-upgrade

# Install Python 3.3:
sudo apt-get install python-software-properties
sudo add-apt-repository ppa:fkrull/deadsnakes    
sudo apt-get update    
sudo apt-get install python3.3

# Install virtualenv
sudo apt-get install python-pip
sudo pip install pip --upgrade
sudo pip install virtualenv

# Install necessary packages:
sudo apt-get install python-dev python3.3-dev libzmq-dev

# Build a venv, using Python 2.7, which works:
~$ mkdir test_ipython2.7
~$ cd test_ipython2.7
~/test_ipython2.7$ virtualenv -p python2.7 venv
~/test_ipython2.7$ source venv/bin/activate
(venv)~/test_ipython2.7$ pip install ipython[all]==1.1.0
(venv)~/test_ipython2.7$ ipython notebook
# Works, opening an ipynb that runs Python 3.3

# Build a venv, using Python 3.3, which fails:
~$ mkdir test_ipython3.3
~$ cd test_ipython3.3
~/test_ipython3.3$ virtualenv -p python3.3 venv
~/test_ipython3.3$ source venv/bin/activate
(venv)~/test_ipython3.3$ pip install ipython[all]==1.1.0
(venv)~/test_ipython3.3$ ipython notebook
# Fails, says that ipython is not installed, despite having reported otherwise

在尝试在3.3 virtualenv中安装ipython之后,我收到一条消息,说明已成功安装了ipython和许多支持包.但是当我尝试运行ipython或ipython笔记本时,我收到一条消息,表明没有安装ipython.观察安装过程,并在输出中向后滚动,我找不到任何明显的失败.我甚至从源代码安装了zmq,所以我安装了zmq 4.0.3,ipython在安装过程中找到了它.

谁能发现我哪里错了？
