Mac Nodejs Learning notes build the first NODEJS development environment

I. Preparation

Installed Nodejs (NODE,NPM)

Two.

1. Create a workspace:

$ mkdir ~/workspace/nodejs/$ CD ~/workspace/nodejs/$ Pwd/users/vincent/desktop/my/workspace/nodejs

2. Install Express

$ sudo npm install express -g[email protected] /usr/local/lib/node_modules/ express├── [email protected]├── [email protected]├── [email protected]├── [ email protected]├── [email protected]├── [email protected]├── [email  protected]├── [email protected]├── [email protected]├── [email protected]├──  [email protected]├── [email protected]├── [email protected]├── [email  protected]├── [email protected]├── [email protected]├── [email protected] ├── [email protected]  ([email protected]) ├── [email protected]  ([email  protected]) ├── [email protected]  ([email protected]) ├── [email protected]   ([email protected], [email protected]) ├── [email protected]  ([email  Protected], [email protEcted], [email protected]) ├── [email protected]  ([email protected]) └── [ email protected]  ([email protected], [email protected])

3. Set up Express project to start the first project

$ express-e Nodejs-demo-bash:express:command not found

I have also been in the pit, looking for the mother looked for a bit, from the results found a more satisfactory result:

• 1 Express Command not found

• Initial operation : Follow the "Nodejs Development Guide" knocking npm install -g express , installed, on the Linux command line knocking on express --help the cause of the above.

• Workaround : Install a packagenpm install -g express-generator

• cause : express3+ has separated the creation of an app into a express-generator, you can't create an app without it

• 2 express-t Ejs microblog created is 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

• What happens : But by looking at the Package.json in the microblog folder, you know that the Ejs template is not created but the Jade template engine

• workaround : Version different, with the wrong command, should be EXPRESS-E microblog (-E is the Ejs template)

• 3 node App.js no effect

• first operation : Follow the Nodejs development guide Tap node app.js at the command line and then use the browser to access the Listening 3000 port

• < Span style= "FONT-SIZE:18PX;" >: Cannot access page

• workaround : Version different, with the wrong command, should be NPM start

The above paragraph is obtained from the http://blog.csdn.net/dai_jing/article/details/38087443 place.

After you find the reason, execute the following command:

$ sudo npm install-g express-generator/usr/local/bin/express-/usr/local/lib/node_modules/express-generator/bin /express[email protected]/usr/local/lib/node_modules/express-generator├──[email protected] ([email protected]) └──[ Email protected] ([email protected])

Start the program

$ NPM start> [email protected] start/users/vincent/desktop/my/workspace/nodejs/nodejs-demo> node./bin/www

Also open a terminal test if it starts successfully

$ Curl localhost:3000<! DOCTYPE html>
