在需要使用最新代码或者需要进行定制化开发时，则一般需要从源码方式进行安装，在本文中对这种使用方式进行介绍。

# 整体步骤 #

和大多数基于npm打包的应用一样，按步骤使用如下命令即可完成Node-RED的安装与服务启动。

*  步骤1: 下载源码

> 执行命令： git clone https://github.com/node-red/node-red.git

*  步骤2: 安装依赖

> 执行命令： cd node-red; npm install

*  步骤3: 执行构建

> 执行命令： npm run build

*  步骤4: 运行Node-RED

> 执行命令： npm start

# 安装与说明 #

    ---------------------------------------------------------------------
    Your flow credentials file is encrypted using a system-generated key.
    
    If the system-generated key is lost for any reason, your credentials
    file will not be recoverable, you will have to delete it and re-enter
    your credentials.
    
    You should set your own key using the 'credentialSecret' option in
    your settings file. Node-RED will then re-encrypt your credentials
    file using your chosen key the next time you deploy a change.
