Nodejs / Express“原型”错误

发布于 2024-12-08 11:44:34 字数 863 浏览 0 评论 0原文

我在尝试启动我的节点应用程序时出现以下错误：

TypeError: Cannot read property 'prototype' of undefined

完整错误：

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 Object.<anonymous> (/home/node/node_modules/express/lib/express/index.js:28:31)
    at Module._compile (module.js:432:26)
    at Object..js (module.js:450:10)

我已注意到关于同一错误的上一个问题： Express 框架给出了一个非常奇怪的错误。我尝试安装旧版本的 connect，但这不起作用，并且收到了相同的错误。

节点版本：v0.5.9-pre

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 Object.<anonymous> (/home/node/node_modules/express/lib/express/index.js:28:31)
    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

根据对您问题的评论，您可以发布您正在使用的代码吗？您很可能缺少 app.use 语句

听起来您缺少一些依赖项。将 package.json 文件添加到项目目录的根目录

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

然后，从项目目录运行 npm install -d 。如果您使用jade而不是ejs，请将package.json上的该行更改为jade，它是当前版本。

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.
