PostCSS does not read and not print file, from folder "src" to "dest"

I installed grunt-postcss and autoprefixer plug-in, but when I try to configure PostCSS with metod of the plug-in load-grunt-config, Autoprefixer and other plug-in, do nothing and do not have allert or error.

This is output from console:

$ grunt postcss
Running "postcss:postcss" (postcss) task
Done.

When I configure grunt in the standard way, PostCSS it works correctly.

This is my postcss.js file, put inside of grunt folder:

module.exports = {
  postcss: {
    options: {
      processors: [
        require('autoprefixer')(),
      ]
    },
    dist: {
      src: '<%= project.stylesheets %>/src/main.css',
      dest: '<%= project.stylesheets %>/dest/main.css'
    }
  }
};

You have no idea how to solve it

Thanks for your help

Hi @immagimario, ok I’ve checked your https://github.com/immagimario/start-web-site and found a reason: you have mistake in your postcss.js config file, please remove dist, so it should look something like this:

 module.exports = {
  postcss: { // please note: in this case this is target name not plugin name (so you can put any keyword, like: foo or dist or production etc.)
    options: {
      processors: [
        require('autoprefixer')(),
      ]
    },
    src: '<%= project.stylesheets %>/src/main.css',
    dest: '<%= project.stylesheets %>/dest/main.css'
  }
};

Hi @immagimario,

please, run grunt postcss --debug, grunt --config-debug and provide output of both commands.
