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/recordseries.png'

What's funny is that each time I run the command grunt imagemin again, it manages to process a few more files and ends by outputting the same error about another file.

I'm using

node v0.10.24
npm 1.3.21
grunt@0.4.2
grunt-contrib-imagemin@0.5.0 node_modules/grunt-contrib-imagemin
+-- filesize@2.0.0
+-- async@0.2.9
+-- chalk@0.4.0 (has-color@0.1.2, ansi-styles@1.0.0, strip-ansi@0.1.1)
+-- image-min@0.1.2 (mkdirp@0.3.5, cache-file@0.1.2, mout@0.7.1, optipng-bin@0.3.1, jpegtran-bin@0.2.3, gifsicle@0.1.4)

Here is my grunt config for imagemin task:

grunt.config('imagemin', {
    options: {
        optimizationLevel: 3, // 0 to 7, default =7)
        // pngquant: true
    },
    dynamic: {                                          // Multiple target
        files: [{
            expand: true,                               // Enable dynamic expansion
            cwd: '<%= context.source %>/assets/img/',   // equal to app/wesource/assets/img/
            src: ['!**/*-'+arrayToRegexStr(platformIgnoreList)+'**', '**/*.{png,jpg,jpeg,gif}'],                // Actual patterns to match //
            dest: '<%= context.public %>/assets/img/'   // equal to app/public/assets/img/
        }]
    }
});

Answer 1

Uninstalling version 0.5.0 and going back to version 0.3.0 with the following commands should restore the prior functionality:

npm uninstall grunt-contrib-imagemin

npm install --save-dev grunt-contrib-imagemin@0.3.0

There is an issue, https://github.com/gruntjs/grunt-contrib-imagemin/issues/140 , that is being worked on, and when it is fixed it should be safe to upgrade.

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 %>'
        }]
    }
}

Answer 3

Try to use cache: false

worked for me.

Answer 4

我能够通过卸载我在系统范围内意外安装的optipng来解决问题。

Answer 5

I had the same issue with grunt-contrib-imagemin and it was because I was running grunt with sudo.

My fix was to do a chown and a chmod on the entire structure then run grunt without sudo...

什么对我有用的是一个干净的安装节点模块我删除了node_modules目录并做了npm安装后，它再次为我工作
