我正在尝试在Anaconda上安装软件包，并且不断出现环境不一致的错误。我已经尝试过此post中的所有解决方案（我在这里列出了它们），但错误仍然相同：
1）更新conda失败：
conda update --all
2）安装anaconda失败：
conda install anaconda
3）此失败：
conda activate base
conda install anaconda
conda update --all
4）这也失败了：
conda install -c anaconda anaconda
我还尝试过更新导致不一致的单个程序包，例如，我尝试过：
conda update seaborn
在所有情况下，我都会遇到以下错误：

然后我尝试了以下操作：
pip uninstall setuptools
conda install -c anaconda setuptools
当我终于厌倦了更新conda（conda update --all）时，再次出现不一致的错误，如下所示：
