Express app throws 500 TypeError:Object#<EventEmitter>没有方法'hrtime'

Question

我的webapp的暂存实例抛出一个错误:

Express
500 TypeError: Object #<EventEmitter> has no method 'hrtime'
   at Object.logger [as handle] (F:\approot\node_modules\express\node_modules\connect\node_modules\morgan\index.js:96:28)

摩根/ index.js中的第96行:

req._startAt = process.hrtime();

这只发生在我们部署到Azure的副本上.我们可以直接在机器上通过节点运行Express服务器,一切看起来都很完美.

我们刚刚开始在最近的部署中遇到此问题.知道从哪里开始寻找？我找不到任何类似的问题来搜索Express或Morgan的Github问题.谷歌也没有帮助.

process.hrtime()仅存在于节点v0.8.x和更新版本中.所以你需要以某种方式升级到更新版本的节点(最新的稳定版本更好).
