这篇文章将介绍一下使用npm进行Node-RED本地本地安装的方法。

# 本地安装 #

使用npm即可完成安装，执行命令如下：

> 执行命令：npm install -g --unsafe-perm node-red

*  本地版本确认

liumiaocn:~ liumiao$ npm -v
    6.4.1
    liumiaocn:~ liumiao$ node -v
    v10.15.3
    liumiaocn:~ liumiao$

*  安装Node-Red

liumiaocn:~ liumiao$ npm install -g --unsafe-perm node-red
    /Users/liumiao/.nvm/versions/node/v10.15.3/bin/node-red -> /Users/liumiao/.nvm/versions/node/v10.15.3/lib/node_modules/node-red/red.js
    /Users/liumiao/.nvm/versions/node/v10.15.3/bin/node-red-pi -> /Users/liumiao/.nvm/versions/node/v10.15.3/lib/node_modules/node-red/bin/node-red-pi
    
    > bcrypt@3.0.6 install /Users/liumiao/.nvm/versions/node/v10.15.3/lib/node_modules/node-red/node_modules/bcrypt
    > node-pre-gyp install --fallback-to-build
    
    node-pre-gyp WARN Using request for node-pre-gyp https download 
    [bcrypt] Success: "/Users/liumiao/.nvm/versions/node/v10.15.3/lib/node_modules/node-red/node_modules/bcrypt/lib/binding/bcrypt_lib.node" is installed via remote
    + node-red@1.0.4
    added 334 packages from 340 contributors in 19.568s
    liumiaocn:~ liumiao$

*  版本和使用方法确认

liumiaocn:~ liumiao$ node-red -help
    Node-RED v1.0.4
    Usage: node-red [-v] [-?] [--settings settings.js] [--userDir DIR]
                    [--port PORT] [--title TITLE] [--safe] [flows.json]
    
    Options:

# 启动服务 #

使用-p可以指定服务端口，但也可以直接启动，缺省端口为1880

> 执行命令：node-red -p 8080

liumiaocn:~ liumiao$ node-red -p 8080

    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.
