[开发工具]【已解决】报错“Exception: Jupyter command `jupyter-notebook` not found“ 及 not on PATH 问题（bash_profile配置）

mac os

1.pip install notebook 安装

Installing Jupyter

pip install notebook

2. 安装jupyter 后，报错jupyter-notebook not found

参考报错“Exception: Jupyter command jupyter-notebook not found“ 重新安装。

pip3 install --upgrade --force-reinstall --no-cache-dir jupyter

3. 出现permission 问题

指定--user再次安装

pip3 install --upgrade --force-reinstall --no-cache-dir jupyter --user

4. 出现安装目录not on path问题

 WARNING: The scripts jupyter-dejavu and jupyter-nbconvert are installed in '/Users/Rachel1900/Library/Python/3.8/bin' which is not on PATH.

5.解决

参考：

• The script is installed in directory, which is not PATH
  在mac ~/.bash_profile 中增加jupyter notebook 安装路径alias jupyter='/Users/Rachel1900/Library/Python/3.8/bin/jupyter'。

运行，验证。问题解决。

Rachel1900 (master #) ~
$ open ~/.bash_profile
Rachel1900 (master #) ~
$ source ~/.bash_profile
Rachel1900 (master #) ~
$ jupyter notebook

其他参考

• Permanently add a directory to PYTHONPATH?
