在 Heroku 上部署网站/Web 应用程序时遇到问题

Posted 2023-03-07

【中文标题】在 Heroku 上部署网站/Web 应用程序时遇到问题

【英文标题】：Trouble Deploying a Website/Web App on Heroku

【发布时间】：2019-09-06 22:19:28

【问题描述】：

我正在尝试在 Heroku 上部署一个 Web 应用程序，但它一直在崩溃。

检查日志后，它说它在starting process with command 'node app.js'之前崩溃了

将我的应用推送到 Heroku Git 后，我​​点击了链接，它给了我一个missing script: start。

我在脚本中添加了"start": "index.js"，替换了测试和return 1 string。

现在，我遇到了另一个应用程序错误。

这里是日志：

我预计这将是某种文件命名问题。

【问题讨论】：

"start": "index.js" 是错误的。你应该改用"start": "node index.js"

改变了它，得到了同样的东西。

可能机器无法解析绝对路径/。尝试使用相对路径（./ 和 ../），它们在 Nodejs 中更常见。此外，Nodejs 执行中有许多设计模式，因此我们需要更多信息：入口点、项目文件树、package.json 启动脚本...

之前的评论是指一些require('/app/app.js')you have

【参考方案1】：

嗯，根据你的错误信息 Error: Cannot find module '/app/app.js'

我相信它正在尝试找到您的 app.js，我猜它应该是您的 index.js。你到底在用什么？角？如果是这样，请查看此链接，因为它帮助我了解如何设置 Angular 项目以部署到 Heroku。

【讨论】：

我正在使用 javascript、ejs、nodejs。所以我应该把我的 index.js 到处都改成 app.js 吗？

我没有 Procfile 并且我的 app.json 文件没有正确设置。我发现使用 heroku cli 更容易，然后按照 heroku docs 进行操作 lol

哦，好吧，我完全忘记了 .json 文件，很高兴 heroku cli 实际上让事情变得更容易！
