Description

What steps will reproduce the problem?

When I debug my code file it is showed as following:

Traceback

Hi @Frodox386, thanks for reporting this issue, have you tried to update to the latest Spyder 4 version and see if the error happens?

[leavor]

I used the following command to upgrade to spyder5, and encountered a similar problem, in the win10 operating system.

conda install spyder=5.0.0
conda update qdarkstyle

[andfoy]

@leavor, this seems to be a different issue, which is related to outdated packages on the defaults channel on Anaconda, we are aware of this issue and we are working to fix it as soon as possible. In the meantime, please install Spyder in a separate environment, using the conda-forge channel

conda install spyder -c conda-forge

所以这个问题怎么解决？

[ccordoba12]

@649924403, please update to our latest version (5.3.1) to see if the error is fixed there.

Since it's still not available in Anaconda, you have two options:

1. Use our Windows installer, which you can find here.

2. Create a new environment with conda-forge packages. For that, please close Spyder, open the Anaconda Prompt and run the following commands there:

    conda create -n spyder-cf -c conda-forge spyder
    conda activate spyder-cf
    spyder

Closing due to lack of response.
