我试图降级我的conda版本。使用4.6.2版的conda时，我运行了conda install conda=4.5.12。然后，我去运行其他conda命令，但遇到以下错误：
CondaUpgradeError: This environment has previously been operated on by a conda version that's newer
than the conda currently being used. A newer version of conda is required.
target environment location: /home/selah/anaconda3
current conda version: 4.5.12
minimum conda version: 4.6
我现在陷入困境，无法成功运行任何conda命令。如何才能使conda重新恢复正常工作？
