如何通过Anaconda提示符升级Conda版本？

Question

我正在使用conda安装一些包，系统提示：

==> WARNING: A newer version of conda exists. <==
  current version: 4.7.10
  latest version: 4.10.1

Please update conda by running

    $ conda update -n base -c defaults conda

我的问题是，如何升级到特定版本而不是最新版本，例如conda版本4.9.2？

Answer 1

非常简单！只需使用以下命令，但不要包含 "<< >>" 符号：

conda update conda
conda install anaconda=<<VersionNumber>>

希望这可以解决您的问题。更多信息请参阅Anaconda文档

我遇到了相同的问题，只不过在我的情况下它显示为“最新版本：22.11.1”。从4到22的版本号是否增加得如此迅速？还是这是我的环境出了问题？ - undefined

@qqqqq conda切换到了日历版本控制，4.15之后是22，就像2022年一样。 - undefined

我也遇到了同样的问题，但这似乎更像是个“我也是”而不是一个答案。 - undefined

有人有运气解决这个问题吗？ - undefined

Answer 3

我之前也遇到了同样的错误，以下是解决方法

conda install conda=XX.X.X

或者如之前所提到的，如果是Anaconda，那就是你想要的确切版本。希望能成功。
