Grunt - pkg 未定义

Question

正在执行命令： 默认任务是 concat。

grunt -v

我收到以下错误消息：

Verifying property concat.dist exists in config...Warning: An error occurred while processing a template (pkg is not defined). Use --force to continue.

我猜，pkg就是package.json。我使用占位符

pkg.name in the Gruntfile.js.

这里有什么问题？

Gruntfile.js 摘录：

 concat: {
            options: {
                // define a string to put between each file in the concatenated output
                separator: ';'
            },
            dist: {
                // the files to concatenate
                src: ['www/**/*.js'],
                // the location of the resulting JS file
                dest: 'www-built/<%= pkg.name %>.js'
            }
        }

package.json

我怀疑您的 Gruntfile 缺少在您的配置中设置 pkg 属性的部分。在大多数 Gruntfile 中都可以找到这样的东西。

grunt.initConfig({
  pkg: grunt.file.readJSON('package.json')
});

添加属性应该使 pkg.name 与 package.json 中的内容相同。
