OpenShift 与 socket.io，npm install 无法读取依赖项

Question

在尝试使用socket.io构建openshift上的node.js服务器时，发生以下错误。

npm ERR! install Couldn't read dependencies
npm ERR! install Couldn't read dependencies
npm ERR! Linux 3.10.0-753.el7xtsync.x86_64 
npm ERR! argv "/opt/rh/rh-nodejs4/root/usr/bin/node" "/opt/rh/rh-nodejs4   /root/usr/bin/npm" "install"

但是，代码在我的本地计算机上运行良好，没有任何错误

我使用以下软件包。JSON

{
  "name": "socket_thing",
  "version": "0.0.1",
  "description": "To make a server plugin for superpowers",
  "scripts": {
    "start": "node server.js"
  },
  "main": "server.js",
  "dependencies": {
    "express": "^4.15.2",
    "socket.io": "^2.0.4"
  }
}

有什么原因是为什么依赖性在OpenShift上的处理方式有所不同，因为这似乎是问题所在？

Answer 1

，因此似乎使用Express

的最新版本

"express": "^4.16.2"

package.json解决了问题。
