如何使用命令行从 GitHub Packages 下载包？
我需要从 GitHub Packages 下载一个文件，以便可以将其传输到没有 Internet 连接的计算机上进行离线安装。但不清楚如何下载该文件。
例如，让我们考虑 GitHub Packages 上 Homebrew 组织
中的
wget 包。
我成功地使用以下命令下载了清单
curl -o manifest.json -v -H "Authorization: Bearer QQ==" -H 'Accept: application/vnd.oci.image.index.v1+json' https://ghcr.io/v2/homebrew/core/wget/manifests/1.24.5
这是上述命令的执行示例：
user@disp897:~$ curl -o manifest.json -v -H "Authorization: Bearer QQ==" -H 'Accept: application/vnd.oci.image.index.v1+json' https://ghcr.io/v2/homebrew/core/wget/manifests/1.24.5

但是，我不知道如何解析清单文件并使用它从 GitHub 容器注册表下载实际的包。
如何使用
curl您可以使用 gh 命令下载版本。
# download all assets from a specific release
$ gh release download v1.2.3
# download only Debian packages for the latest release
$ gh release download --pattern '*.deb'
# specify multiple file patterns
$ gh release download -p '*.deb' -p '*.rpm'
# download the archive of the source code for a release
$ gh release download v1.2.3 --archive=zip
