我jupyter这里有可执行文件：/usr/local/bin/jupyter
我知道我以前一直在使用 Ubuntu 发行版中的 Python 2（没有 Anaconda），所以我认为它jupyter来自系统pip2安装，但我找不到方法来证明这一点，有吗？
假设前面的情况，我已经完成了这两项操作：sudo /usr/local/bin/pip2 uninstall jupyter和这sudo /usr/local/bin/pip2 uninstall notebook（即使在中/usr/local/bin，我仍然需要，sudo因为出于某种原因，似乎其中的所有文件都属于root），但我一直看到这里的可执行文件：/usr/local/bin/jupyter
另外：我知道那jupyter是受影响的，因为现在命令：jupyter notebook给出了这个输出Error executing Jupyter command 'notebook': [Errno 2] No such file or directory。
我该如何卸载它？为什么pip2无法删除该可执行文件？
编辑：
我目前在我的文件系统上看到这个：
ls -lah /usr/local/bin | grep jupyter
-rwxr-xr-x 1 root root 222 May 6 2017 jupyter

我尝试重现您的情况，但我没有安装 jupyter。因此首先：
sudo pip2 install jupyter
它下载了 jupyter 以及相当多的其他软件包，但首先出现一些错误，然后在重新运行时重复出现：
x86_64-linux-gnu-gcc -pthread -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fno-strict-aliasing -Wdate-time -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security -fPIC -I/usr/include/python2.7 -c _scandir.c -o build/temp.linux-x86_64-2.7/_scandir.o
_scandir.c:14:20: fatal error: Python.h: No such file or directory
compilation terminated.
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
尽管如此，至少 jupyter 可执行文件似乎已经安装好了：
$ jupyter
usage: jupyter [-h] [--version] [--config-dir] [--data-dir] [--runtime-dir]
[--paths] [--json]
[subcommand]
jupyter: error: one of the arguments --version subcommand --config-dir --data-dir --runtime-dir --paths is required
$ whereis jupyter
jupyter: /usr/local/bin/jupyter
但是当我尝试卸载它时：
sudo -H pip2 uninstall jupyter
Skipping jupyter as it is not installed.
如果您在卸载时遇到同样的问题，那么问题可能是 jupyter 一开始就没有正确安装。
但是，我最终能够通过安装 Python dev headers: 正确安装它sudo apt install python-dev。是的，sudo pip2 uninstall jupyter执行成功，但/usr/local/bin/jupyter之后我仍然可以运行。
卸载jupyter-console包（通过找到pip-autoremove -L）也没有起到作用，尽管从名字上看人们可能认为它应该起作用。
但后来我尝试用一种古老的“诺顿指挥官”方法来检查里面有什么/usr/local/bin/jupyter。幸运的是，这只是一段简单的 Python 代码，我注意到第 7 行有一个有趣的包引用：
from jupyter_core.command import main
然后就完成了！
$ jupyter
usage: jupyter [-h] [--version] [--config-dir] [--data-dir] [--runtime-dir]
[--paths] [--json]
[subcommand]
jupyter: error: one of the arguments --version subcommand --config-dir --data-dir --runtime-dir --paths is required
$ sudo -H pip2 uninstall jupyter-core
Uninstalling jupyter-core-4.4.0:
Would remove:
/usr/local/bin/jupyter
/usr/local/bin/jupyter-migrate
/usr/local/bin/jupyter-troubleshoot
/usr/local/lib/python2.7/dist-packages/jupyter.py
/usr/local/lib/python2.7/dist-packages/jupyter_core-4.4.0.dist-info/*
/usr/local/lib/python2.7/dist-packages/jupyter_core/*
Proceed (y/n)? y
Successfully uninstalled jupyter-core-4.4.0
$ jupyter
bash: /usr/local/bin/jupyter: No such file or directory
因此，整个问题在于pip没有删除uninstall它在期间自动下载的依赖项install。
更新：关于您在卸载 jupiter / notebook 时遇到的消息 - 我没有收到任何消息，但它们似乎与讨论的问题无关：
目录“/home//.cache/pip/http”或其父目录不属于当前用户，并且缓存已被禁用。请检查该目录的权限和所有者。如果使用 sudo 执行 pip，您可能需要 sudo 的 -H 标志。
如果我运行 ，也会出现这种情况sudo pip <anything>，而不是sudo -H pip <anything>。似乎是无害的。
You are using pip version 9.0.1, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
我已经有 pip 10.0.1 – 这就是我看不到这个的原因。
除了这些警告之外，据我所知，两个包都已正确卸载。
关于需要sudo，我并不感到惊讶，因为通常pip install *会在系统范围内安装软件包，并且您不太可能在/usr/local/lib/python*没有 root 的情况下写入。 pip 中存在参数--user来解决这个问题，更详细的答案在这里：https://stackoverflow.com/questions/42988977/what-is-the-purpose-pip-install-user
