“conda install”显示解决环境：失败，PackagesNoutFoundError

Question

我在 Mac OS 中被 conda 卡住了。

Conda 命令，如“conda install”、“conda update”不起作用。当我运行这类命令时，它显示“Solving environment: failed”、“PackagesNotFoundError”。我粘贴了下面的示例。

我尝试重新安装 anaconda，但我什至无法运行“conda install anaconda-clean”。它显示了与下面相同的结果。

$conda update conda
Collecting package metadata (current_repodata.json): done
Solving environment: failed
Collecting package metadata (repodata.json): done
Solving environment: failed

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.

我想这可能是因为我使用“pip”来安装一些软件包，而不是“conda”。

如果您需要更多信息，请告诉我。感谢您的关注。

我遇到了同样的问题，最后通过使用本指南手动卸载 conda 和 anaconda 解决了这个问题（尽管我无法确定链接中步骤 4 的开头或结尾，这涉及删除 Library 文件夹中的包服务文件） ：

https://nektony.com/how-to/uninstall-anaconda-on-a-mac

1.退出 Anaconda 应用并使用活动监视器强制退出在后台运行的任何 Anaconda 进程。

3.从 Applications 文件夹中删除 Anaconda 应用程序。

4.在终端中使用 rm -rf 删除以下内容：

~/anaconda3
~/.bash_profile-anaconda3.bak
~/.condarc
~/.conda
~/.anaconda

然后我重新安装了 anaconda，现在一切似乎都正常了。
