express - 大多数中间件不再与 Express 捆绑

Question

我知道这是一个非常古老的问题，并且有很多关于此的帖子，但我的情况不同

错误：大多数中间件（如会话）不再与 Express 捆绑在一起，必须单独安装。

我已经设置session好了

const app = express();

app.set('trust proxy', 1) // trust first proxy
app.use(session({
  secret: 'keyboard cat',
  resave: false,
  saveUninitialized: true,
}))

但是heroku仍然向我抛出错误

这是错误的完整日志

我建议在使用之前在 app.js 文件的顶部要求快速会话。

const session = require('express-session');
