] );
});
};
当我运行grunt获取错误信息为Noconcatfound found。
我一直在尝试2个小时来解决这个问题,但没有结果帮助我解决问题。
我会尝试检查src / index.html中的构建块,并检查路径是否正确指向useminPrepare将要连接的资源。我现在正在努力解决像这样的问题:S

My grunt file is shown below:
module.exports = function(grunt) {
// Project configuration.
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),

},

dest: 'dist/<%= pkg.name %>.min.js'
}
},
watch: {
js: {
files: ['src/**/*.js'],
options: {
livereload: '<%= connect.options.livereload %>'
}
},
livereload: {
options: {
livereload: '<%= connect.options.livereload %>'
},

}
},

// Load the plugin that provides the "uglify" task.

grunt.registerTask('serve', function(target) {
grunt.task.run([
'connect:livereload',
'watch'
]);
});
};
when i run grunt getting error message as "No "concat" targets found". I have been trying for 2 hours to solve this problem but no result pls help me to get the solution.
Way too late, but just in case it is useful for somebody else: I believe useminprepare will auto-generate a concat configuration and feed it to the grunt task runner, so above responses are not quite accurate I would say.
I would try reviewing the build blocks in src/index.html and check that the paths point properly to the resources that useminPrepare will concatenate. I'm struggling now with a problem like this :S
