How to carry out raspberry pie Nodejs actual combat to build Web service, I believe that many inexperienced people do not know what to do, so this article summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

The first way: traditional way, not recommended

1. Check the link address of ARMv7 download on http://nodejs.cn/download/

For example: https://npm.taobao.org/mirrors/node/v10.15.3/node-v10.15.3-linux-armv7l.tar.xz

2. Download:

Wget https://npm.taobao.org/mirrors/node/v10.15.3/node-v10.15.3-linux-armv7l.tar.xz

Xd-d node-v10.15.3-linux-armv7l.tar.xz

Tar-xvf node-v10.15.3-linux-armv7l.tar

3. Move the extracted directory to the specified location

Sudo mv node-v10.15.3-linux-armv7l.tar / usr/local/nodejs

4. Link

Sudo ln-s-f / usr/local/nodejs/bin/node / usr/local/bin

Sudo ln-s-f / usr/local/nodejs/bin/npm / usr/local/bin

5. Version testing

Node-v

Npm-v

The second way: use nvm, recommended

Nvm is a special tool for node.js installation and version switching. For more information, please see the relevant documentation, such as https://www.jianshu.com/p/d0e0935b150a.

1. Install nvm:

Curl-o-https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

Source / .bashrc

Check the version number: nvm-- version to determine whether the installation is successful

2. Install node.js:

Go to nodejs.org to find the latest recommended version. Currently: 10.15.3

Installation: nvm install v10.15.3

After installation, you can view the version via node-v and npm-v, which means that node and npm are installed successfully.

3. Install Express:

Npm install express-generator-g

After installation, you can view the help information through the command express-h, indicating that the installation was successful.

4. Create a project myapp:

Express myapp

Cd myapp

Npm install

Run: npm start
