Installation of Node express4.x

4.x it's not an express anymore, it's all done, and you need to install another deployment plugin

Specific:

Follow the Nodejs development guide and Knock npm install -g express ,

installed, the reason for the above is to hit the Linux command line express --help .

Workaround: Install a packagenpm install -g express-generator

Cause: express3+ has separated the functionality of creating an app for Express-generator,

You can't create an application without it.

Express-t Ejs microblog created not the Ejs template engine but the Jade template engine

Initial action: Follow the Nodejs Development Guide in command-line knocking express -t ejs microblog is used to create the application, the name of the application is microblog, the template engine is Ejs occurrence:

But by looking at the Package.json in the microblog folder, it's not the Ejs template that's created, but the Jade template engine.

Workaround: The version is different, with the wrong command, it should be express -e microblog (-E is Ejs template)

Node App.js does not work initially: follow the Nodejs development Guide and Knock node app.js at the command line,

And then just use the browser to access the listening Port 3000: access to the page

Workaround: The version is different, with the wrong command, should benpm start
