VS代码：无法运行Python交互式窗口

Question

[当我尝试以VS Code运行Python交互式窗口时，出现错误消息：

Jupyter notebook failed to launch. 
Error: Traceback (most recent call last):
  File "C:\Users\Parker\AppData\Local\Programs\Python\Python37\lib\site-packages\nbformat\validator.py", line 12, in <module>

  File "C:\Users\Parker\AppData\Roaming\Python\Python37\site-packages\jsonschema\exceptions.py", line 9, in <module>
    import attr
ModuleNotFoundError: No module named 'attr'

During handling of the above exception, another exception occurred:

    Jupyter notebook format depends on the jsonschema package:

        https://pypi.python.org/pypi/jsonschema

    Please install it first.


Failed to run jupyter as observable with args notebook --no-browser --notebook-dir=C:\Users\Parker\AppData\Local\Temp\e74520b3-6a8d-4e0a-8f80-8ddf2a64bf70 --config=C:\Users\Parker\AppData\Local\Temp\e74520b3-6a8d-4e0a-8f80-8ddf2a64bf70\jupyter_notebook_config.py --NotebookApp.iopub_data_rate_limit=10000000000.0

这里有另一个线程与此问题有关：Can't use Jupyter Notebook: jsonschema apparently missing，但是，按照解决方案中的所有步骤操作后，错误仍然存​​在。如果有人能够提供可能的解决方案，我将不胜感激。

Answer 1

您需要用代码分别安装jupyter笔记本。

给出说明：Jupyter notebook

Answer 2

所以我最终卸载并重新安装了Anaconda和VS Code，它解决了问题。

编辑： Akshat Zala帮助我找到了潜在的问题。我试图在全新的Anaconda环境中运行“交互式窗口”。这意味着我尚未安装Jupyter Notebook，因此，交互式窗口将无法使用。我通过激活conda环境然后运行命令'conda install -c conda-forge notebook'解决了这个问题。
