这里的错误确实相当隐蔽。而且我还必须进行大量搜索才能找到解决方案。

但是一旦找到解决方案就相当简单。在您的服务器实例（部署了 dokku 的地方）中，执行以下两个命令：

dokku config:set --global CURL_TIMEOUT=1200

dokku config:set --global CURL_CONNECT_TIMEOUT=180

尝试下载 buildpack 的 curl 命令没有足够的时间来执行。我们只是给他们一点额外的时间。这应该可以解决您的问题。

我最初是在这里找到这些命令的：https://github.com/dokku/dokku/blob/master/docs/deployment/methods/buildpacks.md
