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。
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
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

---------------------------------------------------------------------
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.
