“pip uninstall jupyter”不起作用，但是“which jupyter”返回有效路径[重复]

我正在尝试卸载 jupyter。

pip uninstall jupyter，它给了我这个错误：

Cannot uninstall requirement jupyter, not installed

but which jupyter says

/usr/local/bin/jupyter

我尝试使用pip install pip-autoremove进而pip-autoremove jupyter -y但这给出了这个错误：

Traceback (most recent call last):
  File "/usr/local/bin/pip-autoremove", line 11, in <module>
    sys.exit(main())

Edit

更新问题以包括输出pip list

DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.
jupyter-client (5.1.0)
jupyter-console (5.2.0)
jupyter-core (4.3.0)

您的问题似乎已经得到解答here https://stackoverflow.com/a/52912244/7395911。看看它是否解决了您的问题，或者也许澄清了其中的差异。

与此同时，请查看下面我可以为您提供的提示。

利用虚拟环境 https://pypi.python.org/pypi/virtualenv如果可能的话，它将使您免于将来遇到类似的麻烦。

Run pip install virtualenv.

然后在您的项目文件夹或任何所需的文件夹中调用virtualenv venv.

我将创建一个虚拟环境您将没有安装任何软件包，或者可能只安装几个软件包。

要使用新创建的虚拟环境只需执行source venv/bin/activate.

Now run pip freeze它会向您显示一个干净的包裹列表。

安装你所有的要求像往常一样，我假设你知道怎么做。

然后运行你的jupyter项目。
