【问题描述】：

我正在尝试在运行最新 NodeJS (v7) 的 Openshift 上部署 KeystoneJS 应用程序，在遇到其他一些问题后，我遇到了此错误消息

Warning: connect.session() MemoryStore is not

memory, and will not scale past a single process.
Got SIGTERM, stopping workers...
(node:20870) DeprecationWarning: Using Buffer without `new` will soon stop working. Use `new Buffer()`, or preferably `Buffer.from()`, `Buffer.allocUnsafe()` or `Buffer.alloc()` instead.

我不太确定，这些错误消息中的哪一个可能是根本原因。有没有人有类似的问题？

感谢任何帮助。

【解决方案1】：

您需要在另一个选项卡上启动 MongoDB

 ~: mongod

和转到文件（在您的项目中）：

'node_modules/mongoose/node_modules/mongodb/node_modules/bson/ext/index.js'

改变

bson = require('../build/Release/bson');

到

bson = require('bson');

但是在你遇到另一个问题之后：

DeprecationWarning：在没有 new 的情况下使用 Buffer 将很快停止在职的。使用new Buffer()，或者最好使用Buffer.from()，改为Buffer.allocUnsafe() 或Buffer.alloc()。

不是Error而是localhost:3000不运行，不知道怎么办
