用pip卸载jupyter

Question

我在这里有jupyter可执行文件：/usr/local/bin/jupyter

我知道历史上我一直在使用Ubuntu发行版的Python2(没有Anaconda)，所以我认为jupyter来自一个系统pip2安装，但是我找不到一个方法来证明这一点，有吗？

假设前面的场景，我同时完成了以下操作：sudo /usr/local/bin/pip2 uninstall jupyter和sudo /usr/local/bin/pip2 uninstall notebook (即使在/usr/local/bin中，我仍然需要sudo，因为由于某种原因，这里的所有文件似乎都属于root )，但是我一直在这里看到这个可执行文件：/usr/local/bin/jupyter

另外:我知道jupyter是受影响的，因为现在命令：jupyter notebook给出了输出Error executing Jupyter command 'notebook': [Errno 2] No such file or directory。

我如何卸载它？为什么pip2不删除该可执行文件？

编辑：

我目前在我的文件系统上看到了这样的内容：

ls -lah /usr/local/bin | grep jupyter
-rwxr-xr-x  1 root root  222 May  6  2017 jupyter
-rwxr-xr-x  1 root root  221 May  6  2017 jupyter-console

当jupyter处于不稳定状态时，我看到了这样的情况：

sudo pip2 uninstall jupyter
