我正在使用 grunt 并尝试 uglify 由 concat 任务生成的 js 文件。Concat 工作正常,但 uglify 失败并出现以下错误。
Running "uglify:dist" (uglify) task
>> Uglifying source "dist/myapp.js" failed.
Warning: Uglification failed. Used --force, continuing.
Warning: Cannot read property 'min' of undefined Used --force, continuing.
node --version
输出v.0.11.8-pre
grunt --version
输出grunt-cli v0.1.9 grunt v.0.4.1
这是我的Gruntfile.js
。我从文档中复制了这个并删除了我不需要的任务。
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
concat: {
options: {
separator: ';'
},
dist: {
src: ['src/**/*.js'],
dest: 'dist/<%= pkg.name %>.js'
}
},
uglify: {
options: {
banner: '/*! <%= pkg.name %> <%= grunt.template.today("dd-mm-yyyy") %> */\n'
},
dist: {
files: {
'dist/<%= pkg.name %>.min.js': ['<%= concat.dist.dest %>']
}
}
}
});
grunt.loadNpmTasks('grunt-contrib-concat');
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.registerTask('default', ['concat', 'uglify']);
};
我还在项目目录中运行sudo npm install XXX --save-dev
了grunt
、grunt-contrib-concat
和 grunt-contrib-uglify
。我的项目目录如下所示。
.
├─── src
| └─── // a bunch of files/dirs here
├─── dist
├─── node_modules
├─── .git
├─── package.json
└─── Gruntfile.js
这是运行的输出grunt --verbose --stack --debug

在这一点上,我不知道我错过了什么。谁能帮帮我?
