【问题描述】：

我用 pip 安装了 jupiter 并运行

jupyter notebook

然后我得到了这个错误：

有人知道怎么解决吗？我在谷歌上搜索过，但对这个特定问题没有任何帮助。

标签： python jupyter

【解决方案1】：

我遇到了同样的问题，但只在我机器上的两个 virtualenv 之一中。在 Python-2.7.9 上运行的两个环境中，我都有最新的 pip 和相同版本的 jupyter

通过搜索，我发现了一个similar issue，它建议使用特定版本的 setuptools

pip install setuptools==33.1.1

我的 setuptools 版本是 setuptools-34.2.0 之前的版本。

【解决方案2】：

一开始我用的是 python 2.7.10 ，会报错。将python版本改为2.7.13，重新安装jupyter后，问题解决了：）

可能很简单，但真的很有帮助！
