由于很多同学问我在安装Node-RED时总是报错，这里我就给大家总结几种非常方便，快捷的安装和开发方式。
在安装时，请大家保持网络畅通，很多包是在国外，需要耐心等待，此外npm的源可以切换成淘宝。

安装方式（一）npm安装

首先需要安装nodejs

sudo npm install -g --unsafe-perm node-red
node-red

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.
