在OSX上，`jupyter`命令来自何处

Question

我今天在mac上重新安装了jupyter，发现jupyter命令找不到了。

$ jupyter
zsh: command not found: jupyter

搜索我的python(由Homebrew安装) bin目录，而不是jupyter目录。

所以我检查了包信息：

$ pip3 show -f jupyter
Name: jupyter
Version: 1.0.0
Summary: Jupyter metapackage. Install all the Jupyter components in one go.
Home-page: http://jupyter.org
Author: Jupyter Development Team
Author-email: jupyter@googlegroups.org
License: BSD
Location: /usr/local/lib/python3.7/site-packages
Requires: notebook, ipywidgets, jupyter-console, ipykernel, qtconsole, nbconvert
Required-by:
Files:
  __pycache__/jupyter.cpython-37.pyc
  jupyter-1.0.0.dist-info/DESCRIPTION.rst
  jupyter-1.0.0.dist-info/INSTALLER
  jupyter-1.0.0.dist-info/METADATA
  jupyter-1.0.0.dist-info/RECORD
  jupyter-1.0.0.dist-info/WHEEL
  jupyter-1.0.0.dist-info/metadata.json
  jupyter-1.0.0.dist-info/pbr.json
  jupyter-1.0.0.dist-info/top_level.txt
  jupyter.py

和这里的../../../bin/jupyter完全不一样。

但我确信我可以用同样的轮子包在我的windows PC上安装%python_root%/scripts/jupyter。

那么jupyter命令是从哪里来的，我该如何修复它呢？

感谢@hoefling。

pip uninstall jupyter && pip install jupyter什么也没做。

bin文件夹中的jupyter命令由jupyter-core包提供。

因此，如果您的jupyter包有问题，重新安装所有使用jupyter启动的包比只重新安装jupyter要好得多。
