所以这是我的 gruntfile.js：
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
folders: {
'dist': 'dist',
'app': 'app'
},
// configure jshint to validate js files -----------------------------------
jshint: {
options: {
reporter: require('jshint-stylish'),
ignores: [
'Grunfile.js',
'app/assets/lib/**/*'
]
},
all: [
'app/**/**/*.js',
]
},
// configure uglify to minify js files -------------------------------------
uglify: {
options: {
banner: '/*\n <%= pkg.name %> <%= grunt.template.today("yyyy-mm-dd") %> \n*/\n'
},
build: {
files: {
'dist/js/app.min.js': 'app/js/main.js'
}
}
},
// compile sass stylesheets to css -----------------------------------------
sass: {
dist: {
options: {
style: 'expanded'
},
files: {
'app/assets/css/main.css': 'app/assets/sass/main.sass',
'app/assets/css/variables.css': 'app/assets/sass/variables.sass',
'app/assets/css/typography.css': 'app/assets/sass/typography.sass',
'app/assets/css/reset.css': 'app/assets/sass/reset.sass'
}
}
},
// starting an express server ----------------------------------------------
express: {
dev: {
options: {
port: 9000,
hostname: '0.0.0.0',
bases: ['app'],
livereload: true
}
}
},
// configure watch to auto update ------------------------------------------
watch: {
sass: {
files: ['**/*.{scss,sass}'],
tasks: ['sass'],
options: {
livereload: true
}
},
reload: {
options: {
livereload: true
},
files: ['app/**/*'],
},
}
});
grunt.loadNpmTasks('grunt-contrib-jshint');
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-contrib-sass');
grunt.loadNpmTasks('grunt-contrib-cssmin');
grunt.loadNpmTasks('grunt-express');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.registerTask('default', ['jshint', 'uglify', 'sass', 'express', 'watch:reload']);
};
我的问题：当我启动 grunt 时，它会检查我的 sass 文件并自动将其转换为 css 文件。查看。但是如果我开始 grunt 然后编辑一个 sass 文件，它会识别更改但不会再次将 sass 转换为 css。有人看到错误吗？
干杯!
