为啥当我的 heroku 应用程序崩溃时出现 mongodb 错误？ （在本地工作就好了！）

Posted 2023-03-10

【中文标题】为啥当我的 heroku 应用程序崩溃时出现 mongodb 错误？ （在本地工作就好了！）

【英文标题】：Why do I get a mongodb error when my heroku app crashes? (works locally just fine!)为什么当我的 heroku 应用程序崩溃时出现 mongodb 错误？ （在本地工作就好了！）

【发布时间】：2021-05-22 02:37:57

【问题描述】：

这是我第一次将我的应用程序部署到 Heroku，当我在本地运行它时一切正常，但我无法让它实时启动。我在下面不断收到这些错误，我尝试删除并重新安装没有修复它的 node_modules。如果需要更多信息，请告诉我！

【问题讨论】：

部署时是否运行了 npm install ？因为它说找不到模块'./mongodb_aws'

你提交了带有 mongodb_aws 依赖的 package.json 吗？

删除 node_modules 后，我确实运行了 npm install，然后保存并推送到 heroku master。 mongodb 和 mongoose 都在 package.json 依赖文件中，并且都在当前 node_modules 文件夹中可见。下面我将列出 package.json 文件和我推送到 heroku 时的构建日志。

【参考方案1】：

对于任何有同样问题的人 - 我最终通过将源代码克隆到我的本地计算机来解决了这个问题。我一直在对原始本地文件夹进行故障排除。在我使用以下方法从 heroku 克隆它之后：

$ heroku git:clone -a ims-project
$ cd ims-project

我删除了 node_modules 文件夹和 package-lock.json 文件，然后再次运行 npm install。现在它正在工作！
