[英]Conda error on update: `conda.core.link:_execute(637): An error occurred while installing package 'None'. AssertionError()`
今天通過conda update --all它會下載幾個軟件包並幾乎完成安裝，但最后給出了
Preparing transaction: done
Verifying transaction: done
Executing transaction: done
ERROR conda.core.link:_execute(637): An error occurred while installing package 'None'.
AssertionError()
Attempting to roll back.

當conda install anaconda失敗時，命令conda install conda也為我工作。 我不知道為什么后者不起作用。 否則我會得到ERROR conda.core.link:_execute(637)錯誤。
該問題似乎與env中與您嘗試更新的軟件包版本不兼容的舊軟件包相關聯。 解決了以下步驟：
用conda安裝最新的conda vesrion
conda安裝conda
更新的spyder：
conda update spyder
之后一切都對我好！
