推荐答案

您已将express更新为4.0，但是它现在还没有包含所有中间件，因此您必须手动安装它们.

You have updated your express to 4.0, but it doesn't have all the middleware included now, so you have to install them manually.

请参见移至Express 4.0指南

Express 4不再依赖于Connect，并从其核心中删除了所有内置的中间件，express.static除外.这意味着Express现在是一个独立的路由和中间件Web框架，并且Express版本和版本不受中间件更新的影响.

Express 4 no longer depends on Connect, and removes all the built-in middleware from its core, except express.static. This means Express is now an independent routing and middleware web framework, and Express versioning and releases are not affected by middleware updates.

在没有内置中间件的情况下，您必须显式添加运行应用程序所需的所有中间件.只需执行以下步骤:

With the built-in middleware gone, you must explicitly add all the middleware required to run your app. Simply follow these steps:

安装模块: npm install --save

在您的应用中，需要以下模块: require('module-name');

In your app, require the module: require('module-name');

根据其文档使用模块: app.use(...);

Use the module according to its documentation: app.use( ... );
