Question

在Mac OSX 10.8.4上。我通过ScipySuperpack安装了IPython。它似乎安装得很好。

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

关于我哪里出错的建议？

Answer 1

我在新安装的ubuntu 14.04中遇到同样的问题

似乎pip install jinja2出错，我的解决方案是

pip uninstall jinja2
sudo apt-get install python-jinja2

Answer 2

通过pip install jupyter安装jupyter后出现此问题。对我有用的解决方案是直接从https://pypi.python.org/pypi/MarkupSafe下载markupsafe tarball并通过sudo python setup.py install安装。

Answer 3

使用ScipySuperpack安装的pip版本，执行

pip install ipython[all]

这应该修复所有依赖项。

使用ScipySuperpack的IPython Notebook：缺少markupsafe依赖项
