Question

我是meteor和Heroku的新手，并尝试使用Heroku和mongoDB地图集从流星设置教程todo应用程序。当我使用meteor启动该应用程序时，该应用程序可以在具有本地主机的本地计算机上完美运行。现在，我想将其部署在Heroku上。因此，我创建了一个mongoDB免费帐户，为所有IP地址添加了白名单，创建了一个对任何数据库都具有读写权限的数据库用户。然后我得到一个看起来像这样的连接字符串（我不确定那是否是流星的正确连接字符串）：

mongodb+srv://DATABASEUSER:PASSWORD@todoauto-ivrrg.mongodb.net/test?retryWrites=true

我选择“连接您的应用程序”，并将其选择为驱动程序“ Node.js”，并将其版本选择为“ 3.0或更高版本”。

在下一步中，我创建了我的Heroku免费帐户，为我的终端下载了CLI，登录到Heroku，创建了本地git存储库，创建了新应用，并添加了从“ admithub / meteor-horse”构建包，将MONGO_URL设置为来自MongoDB Atlas的连接字符串，并将ROOT_URL设置为https://todoauto.herokuapp.com。然后我把所有东西都推到了Heroku。

我不确定是否需要从流星更改或添加任何东西到Todo应用程序。当我尝试使用Heroku启动应用程序时，它立即崩溃。我检查了日志，这就是我得到的：

我希望我的问题能对我有所帮助，我对一切都很陌生，并阅读了许多指南，了解如何与Heroku一起设置流星，并遵循了所有步骤。在尝试启动应用程序之前，我没有收到任何错误。

Answer 1

连接到MongoDB Atlas数据库时，我遇到了这个问题，该数据库的MongoDB服务器版本为4.0.10（可能太新了，无法与旧示例一起使用）。

请尝试以下示例的分支，它使用节点mongodb驱动程序的更新版本：

https://github.com/onezoomin/todos

即：

git clone https://github.com/onezoomin/todos
