标签： python anaconda jupyter-notebook jupyter file-not-found

我重新安装了Anaconda 3.7，并尝试通过执行以下操作打开Jupyter笔记本：

  1. 未安装的Anaconda 3.6。
  2. 删除注册表中的所有anaconda，jupyter和python键。
  3. 删除文件系统上的所有anaconda，jupyter和python文件和文件夹。
  4. 重新启动。
  5. 已安装64位Anaconda 3.7（在Windows 10 Pro 64位上）。我在安装程序中勾选了“添加到路径”选项。
  6. 打开PowerShell。
  7. 使用jupyter notebook命令启动jupyter笔记本。
  8. 尝试通过在浏览器中选择笔记本来打开笔记本。

我收到以下错误：

使用conda update --all更新软件包没有区别。

使用jupyter lab会出现相同的错误。

有人知道为什么会这样以及如何解决吗？

我提交了bug with the Jupyter project。

尝试一次：1.打开Anaconda提示符 2.转到C：\ Users \ your_name 3.写下jupyter trust untitled.ipynb 4.然后，写jupyter notebook

答案 1 :(得分：0)

在我刚完成conda update --all之后，它似乎可以正常工作。

新版本是：

jupyter                   1.0.0                    py37_7
