没有定义Grunt - pkg。

Question

执行命令：默认任务是串联的。

grunt -v

我得到以下错误消息：

验证属性concat.dist存在于config...Warning中:在处理模板时发生错误(未定义pkg)。继续使用武力。

我想，pkg是package.json。我使用占位符

pkg.name in Gruntfile.js.

这里有什么问题？

Gruntfile.js节选：

 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缺少一个在您的配置中设置pkg属性的部分。在大多数Gruntfile中，通常都会出现类似的情况。

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

添加该属性将使pkg.name与您的package.json中的内容相同。
