我的 Spyder（4.0 版）崩溃了，spyder --reset没有用。我试过conda update spyder了，然后当我在 Anaconda Prompt 中打开 Spyder 时，它会显示这些：

    Traceback (most recent call last):
  File "E:\Anaconda\Scripts\spyder-script.py", line 10, in <module>
    sys.exit(main())
  File "E:\Anaconda\lib\site-packages\spyder\app\start.py", line 205, in main
    mainwindow.main()

    mainwindow = run_spyder(app, options, args)

    main.setup()

    from prompt_toolkit.enums import DEFAULT_BUFFER, EditingMode
ModuleNotFoundError: No module named 'prompt_toolkit.enums'

但我不能conda install prompt_toolkit.enums，因为它显示：

Collecting package metadata (repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

PackagesNotFoundError: The following packages are not available from current channels:

  - prompt_toolkit.enums

Current channels:

  - https://repo.anaconda.com/pkgs/main/win-64
  - https://repo.anaconda.com/pkgs/main/noarch
  - https://repo.anaconda.com/pkgs/r/win-64
  - https://repo.anaconda.com/pkgs/r/noarch
  - https://repo.anaconda.com/pkgs/msys2/win-64
  - https://repo.anaconda.com/pkgs/msys2/noarch

To search for alternate channels that may provide the conda package you're
looking for, navigate to

    https://anaconda.org

and use the search bar at the top of the page.

并且prompt_toolkit已经被我重新安装了。但是还是没有什么用处。我只是添加conda list prompt_toolkit如下的输出：

# packages in environment at E:\Anaconda:
#
# Name                    Version                   Build  Channel
prompt_toolkit            3.0.5                         0

有谁能帮助我吗？请！！！我只是想正常使用Spyder！

可能你的prompt_toolkit版本太高，和你的ipython版本不兼容。
您可以尝试安装prompt_toolkit 2.xx。
