我不确定有什么问题，但在运行NewsletterMailer.weekly("username-here@gmail.com").deliver时在控制台中我收到错误URI::InvalidComponentError: bad component(expected host component): localhost:3000
我仔细检查我的设置，一切似乎都很好。这是错误的完整输出：

从您指定为默认主机的网址中删除端口号。 :host密钥的值应该只是主机，而不是主机和端口号。

如果Zajn的回答不起作用，请搜索localhost:3000。你可能把它放在其他地方。当你发现它删除了它，它应该工作。

您的配置中某处可能有config.roadie.url_options = { host: "localhost:3000" }行，也许是development.rb。
road.url_options要求将端口指定为单独的密钥。
尝试
而是config.roadie.url_options = { host: "localhost", port: 3000 }。
