grunt-contrib-imagemin output “Fatal error: ENOENT, no such file or directory”

Question

The command grunt imagemin output the following to a random file.

Fatal error: ENOENT, no such file or directory \'app/public/assets/img/epg/rec         


        

Answer 1

The following solutions works on...

• Ubuntu Linux 13.10 x64
• npm --version = 1.3.11
• node --version = v0.10.21
• grunt-contrib-imagemin = 0.5.0

This is a hack of a solution, but I found the task fails when it looks at the the target directory to see if the PNG image already exists and is optimized. The task would consistently finish when I ran it over and over, each time it would complete a few more images. And I could repeat the problem by running grunt clean, then grunt imagemin over and over.

The error I saw was:

bash Fatal error: ENOENT, no such file or directory 'build-production/path-to/some-image.png'

Solution

Copy the images to the target dir immediately before optimizing them. This way, the check passes and unoptimized images that are copied are replaced by their optimized equivalent.

task

grunt.task.run(
    'copy:imagemin',
    'imagemin'
);

copy configuration

copy: {
    imagemin: {
        files: [{
                expand: true,
                cwd: '<%= exponential.client.src %>',
                src: ['images/**/*.{png,jpg,gif}'],
                dest: '<%= exponential.client.buildProduction %>'
        }]
    }
}

imagemin configuration

imagemin: {
    buildProduction: {
        files: [{
            expand: true,
            cwd: '<%= exponential.client.src %>',
            src: ['images/**/*.{png,jpg,gif}'],
            dest: '<%= exponential.client.buildProduction %>'
        }]
    }
}
