GraphicsMagick报错：this most likely means the gm/convert binaries can't be found

var fs=require("fs");
var gm=require("gm");
gm("./public/imgs/pool.jpg").resize(50,50).write("./public/imgs/pool2.png",function (err) {
if(err){
console.log(err);
}
})原因：
1、没有安装GraphicsMagick
2、没有配置GraphicsMagick的path环境变量
3、安装和配置path环境变量后，机器没有重新启动。
我是没有重启计算机才导致这个错误。以后配置全局变量后一定要重启计算机，这样配置信息才能起作用！
