OS X下安装jupyter并且解决zsh: command not found: jupyter

安装python 和 pip 就不多说了，不会的童鞋，看后面的内容也意义不大，直接进入正题：

1. 安装jupyter

   pip install jupyter

2. 正确的话会提示安装成功

3. 启动

   jupyter notebook

• 然鹅，此时问题出现了:

  “zsh: command not found: jupyter”

• 不要慌，分析一下：

  pip3 show jupyter

  返回

  Name: jupyter

看上去是傻逼的自带python环境问题，不纠结这个，加个环境变量试试；
根据提示：

Location: /Users/yourusername/Library/Python/3.7/lib/python/site-packages

处理一下成为bin的路径

export PATH=/Users/**/Library/Python/3.7/bin:$PATH

加到zsh的环境变量里

vim .zshrc

source一下生效

source .zshrc

等灯等灯 okk啦
