Question

当尝试升级anaconda发行版时，我不断收到以下错误：

Collecting package metadata (repodata.json): done
Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

  - pkgs/free/win-64::anaconda==4.4.0=np112py36_0 -> bzip2==1.0.6=vc14_3
  - pkgs/free/win-64::anaconda==4.4.0=np112py36_0 -> cryptography==1.8.1=py36_0
    [loads of similarly cryptic packages names]
  - pkgs/free/win-64::anaconda==4.4.0=np112py36_0 -> vs2015_runtime==14.0.25123=0

To search for alternate channels that may provide the conda package you're
looking for, navigate to

and use the search bar at the top of the page.

无论我尝试安装或更新什么方式，都会引发此问题： conda update --all和conda update numpy或我尝试过的任何其他软件包都将其引发，因此这不应归因于某个不在频道中的特定软件包。

当我尝试通过conda update -n root conda更新anaconda本身时，甚至会引发这种情况。

我尝试从Anaconda导航器更新numpy。

由于this question，我在频道中添加了conda-forge-无济于事。感谢您的帮助。

编辑：我终于通过完全删除并重新安装Anaconda3来解决了这个问题，但是我仍然不了解到底是什么引起了问题。
