使用nodejs+imageMagick图片合成报错记录

如果是报这个错误  

Could not execute GraphicsMagick/ImageMagick: gm "convert" "/www/temp/168823116798750156.png" "-crop" "1277.7596x1679.63794+0+614.89966" "/www/temp/168823116798750156.png" this most likely means the gm/convert binaries can't be found

{
  code: 400,
  msg: '文件生成出错.',

}

只要在require的地方改一下

var gm = require('gm').subClass({imageMagick: true})

版本不一样写法不一样，真扯淡
