python - 带有 ScipySuperpack 的 IPython 笔记本 : missing markupsafe dependency

Question

在 Mac OSX 10.8.4 上。我通过 ScipySuperpack 安装了 IPython。看起来安装得很好。

要启动，我被告知在命令行中输入ipython notebook --pylab=inline。

但是我收到以下错误

Traceback (most recent call last):   File "/usr/local/bin/ipython", line 8, in <module>

关于我哪里出错的建议？

我在新安装的 ubuntu 14.04 中也遇到同样的问题

pip install jinja2 好像出了问题，我的解决方案是

pip uninstall jinja2
sudo apt-get install python-jinja2
