python - Anaconda 版本更新不起作用（Windows）

问题描述

刚刚尝试通过 Anaconda Prompt 更新 conda，但它不起作用。在我设法以管理员身份打开 Anaconda Prompt 以缓解：当前用户没有对所需路径的写入权限。即使我从 navigator-Enviroments-base root 打开 promt - 在 command 之后打开终端也会出现问题conda update conda。

所以在以管理员身份打开提示后，我从这里使用了来自 conda cheatlist 的命令：https ://conda.io/projects/conda/en/latest/user-guide/cheatsheet.html 我已经更新了 Anaconda 但是当我询问版本号时更新前一样。

我输入：conda update conda 我得到：

Solving environment: \

done

然后我再次检查版本......什么都没有！

（基础）C:\WINDOWS\system32> conda --version conda 4.9.2

我在cheatlist中使用了命令：


(base) C:\WINDOWS\system32>conda update -n base conda
Collecting package metadata (current_repodata.json): done
Solving environment: done

The following packages will be downloaded:

Proceed ([y]/n)?

我再次检查 conda 版本 - 并获得了与更新前相同的旧版本

有什么想法我应该尝试从提示中正确更新 Anaconda 和 Navigator 吗？或者我必须从网站下载新版本并卸载旧版本？非常感谢！

解决方案

您可能想要运行：

conda update conda
conda install anaconda=<version>

看看这个问题。
