Jupyter 筆記本打不開，distutils 錯誤

Question

我在命令提示符下鍵入 jupyter notebook（或 jupyter-notebook），但我得到的是：

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.

我所做的只是從網站上安裝 Anaconda，我不確定它為什么不起作用。

重復Jupyter Notebook 錯誤

Answer 1

嘗試在環境變量 C:\Users\palla\Anaconda3\Lib\site-packages\zmq 中添加此路徑。

然后，如果您收到任何 dll 錯誤意味着嘗試添加此路徑 C:\Users\palla\Anaconda3\Library\bin

Answer 2

我也遇到了這個問題，顯然是由於與之前卸載的 python 沖突引起的。 我刪除了 C:\Users\AppData\Roaming 中的 Python 文件。 現在我的筆記本照常工作。

Answer 3

你安裝了嗎？ ;-)

如果您使用菜單快捷方式或 Anaconda 啟動器來啟動它，請嘗試打開終端或命令提示符並運行命令 jupyter notebook。

如果找不到 jupyter，則可能需要配置 PATH 環境變量。 如果您不知道這意味着什么，並且不想知道，只需（重新）使用默認設置安裝 Anaconda，它應該正確設置 PATH。

如果 Jupyter 出現找不到筆記本的錯誤，請檢查 pip 或 conda 是否安裝了筆記本 package。

嘗試運行 jupyter-notebook（帶連字符）。 這通常應該與 jupyter notebook 相同（帶有空格），但如果有任何區別，帶有連字符的版本是“真正的”啟動器，另一個包裝它。

希望它有幫助，因為它幫助了我
