无法在 Ubuntu 18.04 中打开 Jupyter Notebook

我已经在 Ubuntu 18.04 上使用 pip 安装了 Jupyter Notebook。它显然安装正确，因为当我在终端中输入时：

which jupyter

它返回

/usr/local/bin/jupyter

但是当我jupyter notebook在终端中运行时，它显示以下错误（无论是否带有sudo）：

我正在使用 Python 版本 3.7。如何摆脱此问题？

答案1

好吧，我只安装了 Jupyter Notebook，而没有安装 anaconda。它应该可以工作。但由于一些我不知道的原因，我无法运行它。

因此，正如建议的那样官方页面，我使用 anaconda 安装了 Jupyter，这样做之后，我现在能够使用命令成功运行 Jupyter notebook jupyter notebook。

尽管现在已经通过其他方式解决了该问题，但我仍然想知道我最初遇到的问题是什么，以及如何解决它。
