Error: Unable to read .js file (Error code: EISDIR).

[brandon-arnold]

Hi all,

It seems the grunt rev section in its current form can't distinguish between a directory ending in ".js" and a .js file. Grunt-rev (and subsequently usemin) will fail with

Warning: Unable to read "dist/public/bower_components/spin.js" file (Error code:
 EISDIR). Use --force to continue.

Aborted due to warnings.

In the below Gruntfile.js section, I fixed the problem by singling out each .js/ directory (spin.js is a project name and a .js file, for example) and excluding it. If you can tell me a more general way to do it by regex I would appreciate it.

    // Renames files for browser caching purposes
    rev: {
      dist: {
        files: {
            src: [
                '<%= yeoman.dist %>/public/**/*.js',
                '<%= yeoman.dist %>/public/**/*.css',
                '<%= yeoman.dist %>/public/assets/images/{,*/}*.{png,jpg,jpeg,gif,webp,svg}',
                '<%= yeoman.dist %>/public/assets/fonts/{,*/}*.ttf',
                '!<%= yeoman.dist %>/public/bower_components/openlayers/tests/node.js',
                '!<%= yeoman.dist %>/public/bower_components/spin.js'
          ]
        }
      }
    },

:+1: this problem history.js is the package causing me issues.

Thanks @brandon-arnold your solution saved me from choosing between a library I use and a working build.

I have the same problem.

Anyway thank you @brandon-arnold you saved me also!

Note: I ran into this issue with the Auth0 module also:

Warning: Unable to read "dist/public/bower_components/auth0.js" file (Error code: EISDIR). Use --force to continue.

The solution above for spin.js also fixes the auth0.js problem. You may also need to do the same fix in the 'usemin' configuration section as well, if you have one:

        usemin: {
            html: ['<%= yeoman.dist %>/public/{,*/}*.html'],
            css: ['<%= yeoman.dist %>/public/{,*/}*.css'],
            js: [
                '<%= yeoman.dist %>/public/{,*/}*.js',
                '!<%= yeoman.dist %>/public/bower_components/auth0.js'
            ],

Any package that ends with .js will produce this error.

@ianzepp Your solution doesn't resolve the issue for me.

[brandon-arnold]

@elis: did you add the line to the rev {} section, too, like the first post? Ianzepp only showed half the solution.

[elis]

Yeah, and it solved the problem. Cheers!
