[英]Interactively debugging a Node.js application on Heroku?

My Node.js application runs correctly locally but it has errors once deployed to Heroku. 我的Node.js应用程序在本地正确运行，但是一旦部署到Heroku，就会出错。

I cannot use node-inspector to debug as it requires three ports, and Heroku allows only one port. 我无法使用node-inspector进行调试，因为它需要三个端口，而Heroku仅允许一个端口。

I cant use the debugger built into Node.js because I need a CLI to issue debugging commands. 我无法使用Node.js内置的调试器，因为我需要CLI才能发出调试命令。

Found One-Off Dynos, which allow: 发现了一次性Dynos，它可以：

Running a console (also known as a REPL shell) to run arbitrary code or inspect the app's models against the live database. 运行控制台（也称为REPL Shell）以运行任意代码或针对实时数据库检查应用程序的模型。 (eg rails console, irb, or node) （例如，rails控制台，irb或节点）

I didn't have time to test, but this should let me run the built in node debugger. 我没有时间进行测试，但是这应该可以让我运行内置的节点调试器。
