Jupyter Notebook顯示錯誤

Question

我已經安裝了jupyter，但是每當我嘗試打開筆記本時，它都會顯示以下錯誤：

**/home/hduser/.local/lib/python3.5/site-packages/IPython/paths.py:61: UserWarning: IPython dir '/home/hduser/.ipython' is not a writable location, using a temp directory.
  " using a temp directory.".format(ipdir))
[I 12:31:32.732 NotebookApp] Serving notebooks from local directory: /home/protyay
[I 12:31:32.733 NotebookApp] The Jupyter Notebook is running at:

[I 12:31:32.733 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

Copy/paste this URL into your browser when you connect for the first time,
to login with a token:
    http://localhost:8888/?

No protocol specified
Failed to connect to Mir: Failed to connect to server socket: No such file or directory
Unable to init server: Could not connect: Connection refused
Error: cannot open display: :0**

如果我打開url，則會顯示筆記本，但這無法使我創建或打開新的python3筆記本。

這是與GUI相關的問題。 為了解決這個問題，請在.bashrc中添加以下配置：

出口DISPLAY =：0

在Ubuntu 16.04上的Gnome，正確的值為DISPLAY =：1（不是DISPLAY =：0）

要永久解決此問題，您可以使用gedit或sudo visudo在/ etc / sudoers的末尾添加以下行：

默認值env_keep + =“ DISPLAY”
