python-3.x - 为 jupyter notebook 安装虚拟环境内核会抛出“TypeError：'type' object is not subscriptable”

问题描述

操作系统：Ubuntu 16.04 lts

我使用 virtualenvironmentwrapper 创建了一个虚拟环境“analytics-3”，并且觉得需要使用 Jupyter notebook 来完成一些工作。

Python版本：- 3.5.2

下载 Anaconda3-4.3.0-Linux-x86_64.sh 并在虚拟环境之外安装 anaconda。

“jupyter notebook”运行完美。

我想为这个特定的“analytics-3”虚拟环境制作一个内核并按照以下步骤操作：-

1）激活分析3（使用workon）

2）在里面安装了ipykernel

3）尝试使用以下方法在 jupyter notebook 中安装内核：-

python -m ipykernel install --user --name analytics-3 --display-name "xyz"

收到此错误：-

一个简单的谷歌搜索不亮。请指导我如何解决这个问题。
