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

打开 http://localhost:1880

源码编译

首先需要安装git， nodejs，可以本地开发。

下载安装

git clone https://github.com/node-red/node-red.git
cd node-red

执行 npm install

执行编辑

npm run build

$ npm run build

> node-red@1.2.9 build D:\download\node-red-master\node-red-master
> grunt build

Running "clean:build" (clean) task
>> 0 paths cleaned.

Running "jsonlint:messages" (jsonlint) task
>> 35 files lint free.

Running "jsonlint:keymaps" (jsonlint) task
>> 1 file lint free.

Running "concat:build" (concat) task

Running "concat:vendor" (concat) task

Running "copy:build" (copy) task
Created 10 directories, copied 83 files

Running "uglify:build" (uglify) task
>> 4 files created 1.93 MB → 745.03 kB

Running "sass:build" (sass) task

Running "attachCopyright:js" (attachCopyright) task
Attached copyright to packages/node_modules/@node-red/editor-client/public/red/red.min.js
Attached copyright to packages/node_modules/@node-red/editor-client/public/red/main.min.js

Running "attachCopyright:css" (attachCopyright) task
Attached copyright to packages/node_modules/@node-red/editor-client/public/red/style.min.css

Done.

开发启动运行

执行 npm start

$ npm start

> node-red@1.2.9 start D:\download\node-red-master\node-red-master
> node packages/node_modules/node-red/red.js

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.

打开http://127.0.0.1:1880/

停止服务请使用 ctrl+c

docker启动

首先需要安装Docker

docker run -it -p 1880:1880 -v node_red_data:/data --name mynodered nodered/node-red

打开调试日志

r如果需要使用密码登录

docker run -it -p 1880:1880 -v $PWD/data:/data -e TZ=Asia/Shanghai --name nodered -d nodered/node-red

所有安装启动方式 的访问端口都是1880，
打开htpp://localhost:1880 看到以下页面就表示已经安装，启动成功了
