我想在Heroku上设置Gatsby。我已经按照https://www.gatsbyjs.org/docs/deploying-to-heroku/的步骤进行操作，并按照此处https://devcenter.heroku.com/articles/procfile的说明创建了一个Procfile，但是部署时仍然出现超时错误。该端口似乎开始工作，但是由于某种原因它停止了。
我尝试过将不同的行放入Procfile中，但没有一个起作用。目前，我有web: gatsby serve --port $PORT-这是我尝试放入此文件的最后一件事。我还尝试了web: npm start -- --port $PORT和其他可以轻松搜索的选项。

有什么主意我该如何运作？

您可能要使用gatsby build而不是gatsby serve，因为后者用于本地测试。 gatsby build将为您提供静态资产并优化速度。尝试删除Procfile，然后Heroku应该在package.json中捕获build命令。
