Jupyter 笔记本无法打开，distutils 错误

Question

我在命令提示符下键入 jupyter notebook（或 jupyter-notebook），但得到的只是：

E:\Programas\Anaconda\lib\site-packages\setuptools\distutils_patch.py:25: UserWarning: Distutils was imported before Setuptools. This usage is discouraged and may exhibit undesirable behaviors or errors. Please use Setuptools' objects directly or at least import Setuptools first.

我所做的只是从网站上安装 Anaconda，我不确定为什么它不起作用。

编辑：

复制到Jupyter Notebook error

Answer 1

尝试在环境变量 C:\Users\palla\Anaconda3\Lib\site-packages\zmq 中添加此路径。

然后，如果您收到任何 dll 错误，则意味着尝试添加此路径 C:\Users\palla\Anaconda3\Library\bin

Answer 2

我也遇到了这个问题，显然是与之前卸载的 python 冲突引起的。我删除了 C:\Users\AppData\Roaming 中的 Python 文件。现在我的笔记本正常工作了。

Answer 3

你安装了吗？ ;-)

如果您使用菜单快捷方式或 Anaconda 启动器来启动它，请尝试打开终端或命令提示符并运行命令 jupyter notebook。

如果找不到 jupyter，你可能需要配置你的 PATH 环境变量。如果您不知道这意味着什么，并且不想知道，只需（重新）使用默认设置安装 Anaconda，它应该正确设置 PATH。

如果 Jupyter 出现找不到 notebook 的错误，请使用 pip 或 conda 检查是否安装了 notebook 包。

尝试运行 jupyter-notebook（带连字符）。这通常应该与 jupyter notebook 相同（带有空格），但如果有任何区别，带有连字符的版本是“真正的”启动器，另一个将其包装起来。

希望它有所帮助，因为它帮助了我
