【到处是bug】zsh使用jupyter，command not

确认已经安装jupyter

pip3 install --upgrade pip
pip3 install jupyter

2. 找到jupyter的安装位置

pip3 show jupyter

得到类似下面的结果

➜  ~ pip3 show jupyter

根据location，我们可以找到jupyter的位置

/Library/Frameworks/Python.framework/Versions/3.7/bin/

然后将这个位置添加到命令搜索的路径中。(要注意赋值的时候等号两边不要加空格)

vim ~/.zshrc (如果是bash，那就是.bashrc)
添加如下语句
export PATH=/Library/Frameworks/Python.framework/Versions/3.7/bin/:$PATH

然后重载相关命令

source .zshrc

3. 可以正式开始使用jupyter啦

jupyter notebook
