Question

我最近学习了node.js并希望部署我的项目，我在Heroku上做了。但是，Heroku正在向我提供下面复制的错误消息。虽然我已经记录了错误，但我仍然无法找到解决方案。

以下是日志：

这是错误：

An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details.

Answer 1

node.js服务器在路由/上的HTTP GET请求时崩溃。这不是平台错误，而是代码错误（可能是您的index.js文件）。您需要检查代码行之间的错误：

app.get('/', function(req, res) {
 //likely some syntax error here
}

我强烈建议您使用以下命令在本地计算机上运行应用程序：node index.js，以查看HTTP GET代码的哪一部分导致错误。 CLI将给出导致错误的特定行号。

Heroku Local也是在将应用部署到heroku之前测试应用的绝佳工具。

Heroku应用程序正在崩溃
