gm convert:此图像格式没有解码委托

我在一个AWS EC2实例上得到以下错误(我特别指出,因为我在Mac上没有此问题):

Error: Command failed: gm convert: No decode delegate for this image format (/tmp/5c5830319d29e4678e8691cd-1549705844271.jpg)

该文件确实存在,以防出现可疑情况。

我的配置 转基因 如下:

我正在使用节点模块:

var gm = require('gm');

gm("/tmp/5c5830319d29e4678e8691cd-1549705844271.jpg")
.resize(450, null)
.write("/tmp/5c5830319d29e4678e8691cd-1549705844271-Resized.jpg", (function(err){
  if (err) {
    console.log(err);
  }
}));

我对通用汽车的了解还不够,从这儿到哪儿都去不了。问题似乎是我没有jpeg的“转换器”。问题是-如何设置它以支持大多数图像格式,如:JPG、PNG等?

事先谢谢!
