pip - 如何完全卸载jupyter

Question

我无法打开 jupyter notebook .ipynb 文件(我可以打开 jupyter notebook，但是当我 pip 击 .ipynb 时它退出并出现未知错误)因此我想完全摆脱 jupyter 和 ipython。

我使用 sudo pip uninstall 卸载了 jupyter 和 ipython，还使用了 pip2 和 pip3，但我仍然能够在 找到 jupyter code>/usr/local/bin/jupyter 我也可以用 jupyter 启动它。

如果我现在用 pip 重新安装 jupyter，我会得到和以前一样的错误，所以我想它总是以我仍然安装的方式启动。

那么我该如何卸载呢？只删除二进制文件？

编辑1:如果重要的话，我正在使用 python 2.7 和 Ubuntu 16.04

编辑2:我遇到了与此基本相同的问题 pip uninstall jupyter does not work but which jupyter returns

编辑3:当我尝试打开 jupyter-notebook 时的完整错误输出:

Answer 1

修复 jupyter 错误

您有权限问题:

IOError: [Errno 13] Permission denied: '/home/gustav/.local/share/jupyter/notebook_secret'

卸载不会有帮助，至少不会直接卸载。您可以通过在终端中输入此命令来修复它:

mkdir -p ${HOME}/.local/share/jupyter

这将修复由于 .local/share/jupyter 目录不存在而导致的错误。

完全卸载jupyter

如果您无法解决权限问题，这里是从太空中对 jupyter 进行核攻击的最简单的一组命令:

pip install pip-autoremove
pip-autoremove jupyter -y

根据我刚刚进行的一些测试，您可能还必须在最后运行:

pip-autoremove jupyter-core -y

双击打开.ipynb文件

您无法通过双击打开仅使用 vanilla Jupyter 的 .ipynb。这是设计使然(也可以说是设计缺陷，但是嗯)。您可以使用 nbopen 添加此功能项目。

要在 Ubuntu 上安装，只需在终端中运行以下命令:

python3 -m pip install nbopen
python3 -m nbopen.install_xdg

不过我没有测试过这个，因为我没有运行 Linux。

如何以“正常”方式打开 .ipynb 文件

您无法通过双击打开仅使用 vanilla Jupyter 的 .ipynb。这是设计使然(也可以说是设计缺陷，但是嗯)。

相反，您必须在 Jupyter 文件管理器中打开文件，运行方式如下:

1. 打开一个新的终端窗口(在 Ubuntu 中，您只需输入 Ctrl+Alt+T)。

2. 通过运行 jupyter notebook 启动笔记本服务器

3. 这应该会在您的互联网浏览器中自动打开一个指向 Jupyter 文件管理器的新窗口。如果没有，您的终端中会有一行内容类似

   Copy/paste this URL into your browser when you connect for the first time, to login with a token:
   

   在这种情况下，只需将以下 URL 复制到浏览器窗口的地址栏中，然后按回车键即可。

4. 您现在应该有一个显示 Jupyter 文件管理器的浏览器窗口。使用文件管理器导航到您要打开的 .ipynb，然后单击它即可。

诚然有 pip 令人费解，尤其是一开始。我相信 Jupyter 以这种方式设置的原因可以追溯到其基于服务器的架构，以及设计团队希望它能够轻松/无缝地部署到远程计算机上这一事实。
