Executing transaction: done
ERROR conda.core.link:_execute(637): An error occurred while installing package 'None'.
AssertionError()
Attempting to roll back.

Rolling back transaction: done

AssertionError()
()

Answer 1

当 conda install anaconda 对我失败时，命令 conda install conda 对我也有效。我不确定为什么后者不起作用。否则我会得到 ERROR conda.core.link:_execute(637) 错误。
