方案1

Hey @EgonHeuson, thanks for reporting. This error is fixed in our latest version (5.3.0).

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

1. Use our Mac 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

执行完第一个命令之后的提示

done
#
# To activate this environment, use
#
#     $ conda activate spyder-cf
#
# To deactivate an active environment, use
#
#     $ conda deactivate

这样打开的spyder就是最新的版本5.3.3，而之前有问题的版本是5.1.5

方案2

They updated recently to version 5.2.2, which also fixes this problem. To update to it you need to run

conda update anaconda

conda install spyder=5.2.2
