我在玩Yeoman，grunt，bower，bootstrap和yo Angular应用程序。我试图制作grunt watch .less文件，但我遇到了一些麻烦。 我当然已经用
安装了grunt-contrib-less模块npm install grunt-contrib-less --save-dev
并将其保存到我的package.json。
我已经能够使用代码在其他项目中完成这项工作：
module.exports = function(grunt){
grunt.initConfig({
pkg:grunt.file.readJSON('package.json'),
less:{
development:{
options: {
paths: ['bower_components/bootstrap/less', 'bower_components/bootstrap/dist/css'],
yuicompress: true
},
files:{
'bower_components/bootstrap/dist/css/bootstrap.css' : 'bower_components/bootstrap/less/bootstrap.less',
}
}
},
// running 'grunt watch' will watch for changes
watch: {
files: ['bower_components/bootstrap/less/*.less', 'bower_components/bootstrap/less/*.less'],
tasks: ['less']
}
});
grunt.loadNpmTasks('grunt-contrib-less');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.registerTask('default',['less']);
};
和
module.exports = function(grunt) {
grunt.initConfig({
less: {
development: {
options: {
paths: ["bower_components/bootstrap/less"],
yuicompress: true
},
files: {
"bower_components/bootstrap/dist/css/bootstrap.css": "bower_components/bootstrap/less/bootstrap.less"
}
}
},
watch: {
files: "bower_components/bootstrap/less/*",
tasks: ["less"]
}
});
grunt.loadNpmTasks('grunt-contrib-less');
grunt.loadNpmTasks('grunt-contrib-watch');
};
但我之前没有尝试使用Angular应用程序。它也可能是我做错了路由这么简单，但我已经尝试过很多次了我不知道是不是这样。 完整的东西也在github上https://github.com/Lumberfella/angularApp.git
我已经在Gruntfile.js中有一些监视代码
watch: {
bower: {
files: ['bower.json'],
tasks: ['bowerInstall']
},
js: {
files: ['<%= yeoman.app %>/scripts/{,*/}*.js'],
tasks: ['newer:jshint:all'],
options: {
livereload: true
}
},
jsTest: {
files: ['test/spec/{,*/}*.js'],
tasks: ['newer:jshint:test', 'karma']
},
styles: {
files: ['<%= yeoman.app %>/styles/{,*/}*.css'],
tasks: ['newer:copy:styles', 'autoprefixer']
},
gruntfile: {
files: ['Gruntfile.js']
},
livereload: {
options: {
livereload: '<%= connect.options.livereload %>'
},
files: [
'<%= yeoman.app %>/{,*/}*.html',
'.tmp/styles/{,*/}*.css',
'<%= yeoman.app %>/images/{,*/}*.{png,jpg,jpeg,gif,webp,svg}'
]
}
},
并且想要类似的东西（我认为不是真正有效的代码）
less: {
files: [
'<%= yeoman.app %>/{,*/something.something}*.less'
]
tasks: ['less:developer']
},
观看.less文件，如果可能的话将其变成css文件。

答案很简单，因为我在问题中有解决方案代码。对我来说唯一困难的是在哪里以及如何把它放进去。
首先，我安装了grunt-contrib-less模块，并在我的样式文件夹中创建了另一个bootstrap less文件夹，而不是bower_components（谢谢Mingos！）。 然后我更新了Gruntfile，这就是它现在的样子：
'use strict';
// # Globbing
// for performance reasons we're only matching one level down:
// 'test/spec/{,*/}*.js'
// use this if you want to recursively match all subfolders:
// 'test/spec/**/*.js'
module.exports = function (grunt) {
// Load grunt tasks automatically
require('load-grunt-tasks')(grunt);
// Time how long tasks take. Can help when optimizing build times
require('time-grunt')(grunt);
// Define the configuration for all the tasks
grunt.initConfig({
// Project settings
yeoman: {
// configurable paths
app: require('./bower.json').appPath || 'app',
dist: 'dist'
},
less: {
development: {
options: {
compress: true,
yuicompress: true,
optimization: 2
},
files: {
// target.css file: source.less file
"app/styles/bootstrap.css": "app/styles/less/bootstrap.less"
}
}
},
// Watches files for changes and runs tasks based on the changed files
watch: {
bower: {

正如你所看到的，我在我的styles文件夹中创建了一个新的bootstrap.css，然后我从index.html链接了它：）
答案 1 :(得分：0)
尝试将文件包装在子任务中观察：
watch: {
less: {
files: "bower_components/bootstrap/less/*",
tasks: ["less"]
}
}
此外，还有一句话：您确定要查看通过Bower吸取的文件中的更改吗？观察编辑自己代码而不是组件的目录会不会更有意义？
