Nodejs / Express 'prototype' error

Question

I have the following error while trying to start my node app:

TypeError: Cannot read property 'prototype' of undefined

Full error:

at Object.<anonymous> (/home/node/node_modules/express/lib/express/server.js:87:44)
    at Module._compile (module.js:432:26)
    at Object..js (module.js:450:10)
    at Module.load (module.js:351:31)
    at Function._load (module.js:310:12)
    at Module.require (module.js:357:17)
    at require (module.js:368:17)

    at Module._compile (module.js:432:26)
    at Object..js (module.js:450:10)

I have noted this previous question on the same error: Express framework giving a very strange error . I tried to install the older version of connect, but this did not work and I received the same error.

Node version: v0.5.9-pre

Answer 1

Based on the comments on your question, could you post the code you are using? you are most likely missing an app.use statement

Answer 2

It sounds like you're missing some dependencies. Add a package.json file to the root of your project directory

{
    "name": "myproject"
  , "version": "0.0.1"
  , "private": true
  , "dependencies": {
      "express": "2.4.6"
    , "ejs": ">=0.4.3" 
  }
}

Then, run npm install -d from the project directory. If you're using jade instead of ejs, change that line on the package.json to jade and it's current version.

我从头开始解决此问题，并使用旧版本0.4.8重新安装节点。
