heroku应用程序由于缺少模块而崩溃，但可在localhost上运行

标签： node.js heroku mongoose

我有一个已成功部署到heroku的应用程序，但是当我尝试访问它时，出现此屏幕... enter image description here

日志显示以下内容... enter image description here

我认为引起该问题的错误是Error: Cannot find module 'mongoose'。

这是我的package.json供参考...

'mongoose'npm软件包位于我的package.json中，当我在本地主机上运行该软件包时，一切正常。如果您需要更多信息，请告诉我，谢谢您的阅读！

您要在代码中推送node_modules吗？如果是，请尝试删除该文件夹，然后让Heroku重新安装所有模块。

结果是我没有将github连接到我的heroku。我正在推送到github，但是它没有更新heroku，所以我一直遇到同样的错误。这是我必须在heroku中启用的功能，然后我的编辑才真正显示在heroku中。 enter image description here

另一种选择是每次都在终端中输入git push heroku master。

我要做的最后一件事是在终端机上输入heroku config:set MONGODB_URI='mongodb://<name>:<password>@ds123050.mlab.com:23050/ovodb'，以便heroku访问我的环境变量。
