镜像渠道

Mirroring channels

中文

conda 配置系统有几个键可用于设置镜像上下文。

英文

The conda configuration system has several keys that can be used to set up a mirrored context.

默认设置

The default setup

中文

默认情况下， conda 可以从两个主要位置提供软件包：

• repo.anaconda.com：这是 defaults 通道默认指向的位置。 自 conda 24.9.0 起，此默认值已被标记为即将弃用， 但在旧版本中仍为默认设置。该默认值将在 conda 25.3.0 中被移除。

  此基础位置被硬编码在 default_channels 的默认值中：

  • https://repo.anaconda.com/pkgs/main

  • https://repo.anaconda.com/pkgs/r

  • https://repo.anaconda.com/pkgs/msys2

• conda.anaconda.org：conda 客户端会在此处查找社区通道，例如 conda-forge 或 bioconda。 此基础地址可以通过 channel_alias 配置。

因此，在镜像这些通道时，需要同时考虑这两个来源地址。

英文

By default, conda can serve packages from two main locations:

• repo.anaconda.com: this is where defaults points to by default. The default value has been marked for pending deprecation as of conda 24.9.0, but it is still the default for older versions. In conda 25.3.0, this default will be removed.

  This base location is hardcoded in the default value of default_channels:

  • https://repo.anaconda.com/pkgs/main

  • https://repo.anaconda.com/pkgs/r

  • https://repo.anaconda.com/pkgs/msys2

• conda.anaconda.org: this is where conda clients look up community channels like conda-forge or bioconda. This base location can be configured via channel_alias.

So, when it comes to mirroring these channels, you have to account for those two locations.

镜像 defaults

Mirror defaults

中文

使用 default_channels 覆盖 默认配置 。例如：

英文

Use default_channels to overwrite the default configuration. For example:

default_channels:
    - https://my-mirror.com/pkgs/main
    - https://my-mirror.com/pkgs/r
    - https://my-mirror.com/pkgs/msys2

镜像所有社区频道

Mirror all community channels

中文

重新定义 channel_alias 以指向你的镜像。例如：

channel_alias: https://my-mirror.com

这将使 conda 查找 https://my-mirror.com/conda-forge 、 https://my-mirror.com/bioconda 等处的所有社区频道。

英文

Redefine channel_alias to point to your mirror. For example:

channel_alias: https://my-mirror.com

This will make conda look for all community channels at https://my-mirror.com/conda-forge, https://my-mirror.com/bioconda, etc.

仅镜像部分社区频道

Mirror only some community channels

中文

如果你只想镜像某些社区通道，必须使用 custom_channels。 此设置优先于 channel_alias。例如：

custom_channels:
    conda-forge: https://my-mirror.com/conda-forge

上述配置会使 conda 将 conda-forge 通道解析为 https://my-mirror.com/conda-forge。 而其他所有社区通道仍将从 https://conda.anaconda.org 查找。

备注

欢迎参阅 配置 了解所有可用的配置选项。

英文

If you want to mirror only some community channels, you must use custom_channels. This takes precedence over channel_alias. For example:

custom_channels:
    conda-forge: https://my-mirror.com/conda-forge

With this configuration, conda-forge will be looked up at https://my-mirror.com/conda-forge. All other community channels will be looked up at https://conda.anaconda.org.
