在我刚刚将'connect'模块安装到文件目录后,这个简单的应用程序似乎找不到它。

var connect = require ('connect');

connect.createServer(function(res, req, next) {
    res.simpleBody("Connect you son of a beeeeetch");

}).listen(8000);

Express在内部使用Connect作为其node_modules依赖项之一。
如果您希望在应用中使用Connect,则需要将其添加到package.json并运行npm update
根据设计,每个节点模块都有自己的私有内部依赖项。
如果你想使用任何,你的应用程序也需要安装它们。
这意味着您的应用可以使用不同版本的模块,并且每个模块可以在内部再次使用不同版本而不会发生冲突。

Connect是Express使用的可扩展HTTP服务器框架。特别是Express使用它提供对会话和cookie处理的支持。源代码可以在github上的https://github.com/senchalabs/connect找到。

通常,当节点应用程序“找不到”某些内容时,首先要尝试的是转到https://npmjs.org/package/npm-search并搜索找不到的内容。如果不使用npm,很难在节点生态系统中沿着。
在这种情况下,npmsearch将找到connect,如果转到https://npmjs.org/package/connect,您将找到connect模块的安装说明。
在这种情况下:

npm install connect

npm -g install connect

为每个用户安装连接模块。
在大多数unix发行版上,您可能需要root用户或使用sudo来执行此操作。
或者,你可以将连接依赖项添加到你的项目的package.json文件中--我的看起来像这样:

"express": "3.x" ,
"connect": "2.x"

我还必须使用npm安装buffer-crc 32,methods,debug,fresh,range-parser,cookie-signature和cookie模块,以获得一个工作的express项目。
Happy node hacking:)

连接模块未安装或部分安装,因此请先安装它,然后再次尝试启动服务器

npm install connect

你可以使用下面的命令,如果你忘记安装connect serve-static模块或安装不正确,可能会发生这种情况。

$ npm install connect serve-static

因为不是你安装的您安装了express,而不是connect

我也有同样的问题。节点安装到目录C:\Program Files (x86)\nodejs中。最初我试图从这个目录安装和运行javascript文件,这导致了许多权限问题。
如果您已经将服务器放在该目录中,请尝试将其移动到另一个目录(可能在Documents中),在Node命令提示符下导航到该目录,然后再次尝试运行。
这对我来说是开箱即用的。

我运行了npm config edit,更改了属性行,以消除每行开头的分号。
再次运行npm -g install connect
同样的结果。日志文件包含以下内容:

我想我会使用IIS Express。这 * 数百个文件做一些 * 简单的只是超出了我。

我在express-http-proxy上遇到了同样的问题,解决方案是用npm安装这个包。首先,我安装了全局(-g),它工作正常。在另一个安装中,我不得不使用“--save-dev”。

$ gulp
module.js:338
    throw err;
      ^
Error: Cannot find module 'express-http-proxy'
at Function.Module._resolveFilename (module.js:336:15)
at Function.Module._load (module.js:278:25)
at Module.require (module.js:365:17)
at require (module.js:384:17)
at Object.<anonymous> (/var/opt/jet/workspace/node-js-project/lib/authorization-to-context-header.js:1:75)

at Function.Module._load (module.js:310:12)
at Module.require (module.js:365:17)
at require (module.js:384:17)

安装包

$ npm install express-http-proxy -g
express-http-proxy@0.6.0 /opt/jet/nodejs/node-js/lib/node_modules/express-http-proxy
âââ type-is@1.6.6 (media-typer@0.3.0, mime-types@2.1.4)
âââ raw-body@1.3.4 (bytes@1.0.0, iconv-lite@0.4.8)

或者“-g”不够

$ npm install express-http-proxy --save-dev

吞下工作

$ gulp
