Problem when running homebridge after installing homebridge-yeelight plugin

I intsalled homebridge-yeelight (npm install -g homebridge-yeelight) on my raspberry pi 3, but after running homebridge, it showed an error. Did I do something wrong?

Maybe you need to check your configuration file: config.json.

I checked my config.json with jsonlint

{
“bridge”: {
“name”: “Homebridge Hub”,
“username”: “CC:22:3D:E3:CE:30”,
“port”: 51826,
“pin”: “031-45-154”
},

“platforms”: [
{
“platform”: “yeelight”,
“name”: “yeelight”
}
],
“accessories”: [
]
}

Do you have any other accessories in homebridge? It seems that homebridge or yeelight plugin isn’t correctly installed.

I installed Yeelight like this

npm install -g homebridge-yeelight

Maybe I’m missing “sudo” at the beginning?
