Jupyter Notebook 中的 Kernel 錯誤（Errno 13 Permission denied），Windows 10

Question

我已經在 Windows 10 上安裝了 Jupyter Notebook。我可以執行 jupyter notebook 命令。 它打開並顯示當前路徑目錄的列表。 我還可以創建或打開一個筆記本。 但是當我這樣做時，我在右上角收到 Kernel 錯誤。 單擊它后，出現此 window：

kernel啟動失敗

未處理的錯誤

我文件中的代碼沒有在不同的 colors 中突出顯示，當我運行它時沒有任何反應。

我是編程新手，所以請盡量用簡單的語言給出建議，詳細描述每個步驟。

過去我試過刪除Python，安裝不同版本的Python，安裝Anaconda。 此外，為了與 tensorflow 一起工作，我創建了一個特殊的環境。 但是這個錯誤保持不變。 我懷疑問題是路徑中的雙反斜杠（“//”），但我完全不知道如何解決這個問題。 但也許問題出在別的地方。

Answer 1

同樣的問題在這里。 對我有用的是以管理員身份運行 Anaconda Navigator。 希望它也適合你。

Answer 2

自上次更新 jupyter_client 以來出現此問題。 您可以通過降級到最新版本來暫時解決問題。

conda install jupyter_client=5.3.1

Answer 3

以管理員身份運行解決了，太好了！！

Answer 4

我也有同樣的問題。 我在 Windows 10/64 位上安裝了 Anaconda。 每當我打開 Jupyter Notebook 時，我都會收到 Kernel 錯誤

並且打開 Spyder，我得到了這個錯誤

An error ocurred while starting the kernel
The error is:

但是以管理員身份打開工作正常。
