如何使用node.js和node-imagemagick修复此错误：错误：命令失败：execvp（）：权限被拒绝？

Question

Im getting this error:

Error: Command failed: execvp(): Permission denied

When I do a simple node-imagemagick script:

im = require('imagemagick');
im.identify.path = '/tmp/node_thumbs/';
im.identify('cool.jpg',function(err,features){
  if(err) throw err;
  console.log(features);
});

Any ideas on what could be causing this?

The permission denied is from trying to launch the ImageMagick command, not in the process of executing it.

If you look at the documentation , identify.path is "Path to the identify program." In this case, you're redefining the path to the executable as /tmp/node_thumbs/, which presumably is not the executable.

You probably simply want:

var im = require("imagemagick");
im.identify('/tmp/node_thumbs/cool.jpg',function...
