如何删除一个频道，或者至少指示Conda在其中一个频道网址关闭的情况下不中止？

我正在测试一个有问题的工具，该工具在select t1.department, t1.first_name, t1.salary , case when coalesce(minSalary.salary, 0) > 0 then 'lowest salary' when coalesce(maxSalary.salary, 0) > 0 then 'highest salary' else 'N/A' end as salary_by_department from employees t1 left join (select department, first_name, min(salary) as salary from employees group by department, first_name) minSalary on minSalary.first_name = t1.first_name and t1.department = minSalary.department left join (select department, first_name, max(salary) as salary from employees group by department, first_name) maxSalary on maxSalary.first_name = t1.first_name and t1.department = maxSalary.department group by t1.department, t1.first_name, t1.salary提供了一个Conda存储库，但是现在该存储库已脱机，并且现在所有对@api_view(['GET', 'POST']) def page_list(request): # your code here的调用都失败，并显示以下消息：

我在create命令中没有使用此通道，所以我不知道为什么Conda失败而不是忽略它。如何允许Conda继续或清除频道？

我尝试通过运行以下方式删除频道：

conda create --prefix=./cenv -y python=3.7

输出错误：

Collecting package metadata (current_repodata.json): failed

CondaHTTPError: HTTP 503 SERVICE UNAVAILABLE for url <https://www.idiap.ch/software/bob/conda/linux-64/current_repodata.json>
Elapsed: 00:02.470723

A remote server error occurred when trying to retrieve this URL.

A 500-type error (e.g. 500, 501, 502, 503, etc.) indicates the server failed to
fulfill a valid request.  The problem may be spurious, and will resolve itself if you
try your request again.  If the problem persists, consider notifying the maintainer
of the remote server.

编辑：我的conda config --remove channels https://www.idiap.ch/software/bob/conda是：

CondaKeyError: 'channels': 'https://www.idiap.ch/software/bob/conda' is not in the 'channels' key of the config file

正在运行：

conda info

输出错误：

这些是我的conda config --remove channels https://www.idiap.ch/software/bob/conda/linux-64 conda config --remove channels https://www.idiap.ch/software/bob/conda/noarch的内容：

CondaKeyError: 'channels': 'https://www.idiap.ch/software/bob/conda/<name>' is not in the 'channels' key of the config file

Answer 1

conda config --remove channels https://www.idiap.ch/software/bob/conda

在我的测试中工作。

另一种方法是打开.condarc目录下的$HOME个文件，并注释掉相应的频道行。

Answer 2

据我所知，conda区分频道名称和频道URL。即conda info将输出如下内容：

           channel URLs : https://repo.anaconda.com/pkgs/main/win-64
                          https://repo.anaconda.com/pkgs/main/noarch
                          https://repo.anaconda.com/pkgs/r/win-64
                          https://repo.anaconda.com/pkgs/r/noarch
                          https://repo.anaconda.com/pkgs/msys2/win-64
                          https://repo.anaconda.com/pkgs/msys2/noarch

conda config --show channels将输出

channels:
  - defaults

我认为您必须删除频道名称而不是其网址。

在您的主目录中，还应该有一个名为.condarc的文件，其中包含所有用户的自定义设置，包括通道。您可以使用文本编辑器打开该文件，然后从此处删除频道。

最后还有一个标记--override-channels，它会忽略默认频道以及在.condarc中设置的所有频道，这意味着您必须手动指定要在自己的频道中使用的频道conda命令。
