通过试验和错误并使用heroku回滚，似乎问题不在我的app.js文件中，而是在node_modules中。但是我似乎找不到修复方法。我已经尝试重新安装node_modules。

它在本地工作，但在Heroku上部署时却没有。

突然间我有一个package-lock.json文件。也许那是一个线索？

Answer 1

它抱怨decimal128模块，我会从需要它的文件中仔细检查模块的相对路径。现在看起来它正在与文件“/ decimal128”相同的文件夹中查找。

Answer 2

我通过更新所有内容并将mongodb降级为“mongodb”来修复它：“2.2.33”

由于node_modules，Heroku node.js一直崩溃？
