json文件内是不能写注释的

{
  "name": "test",   //项目名称（必须）
  "version": "1.0.0",   //项目版本（必须）
  "description": "This is for study gulp project !",   //项目描述（必须）
  "homepage": "",   //项目主页
  "repository": {    //项目资源库
    "type": "git",
    "url": "https://git.oschina.net/xxxx"
  },
  "author": {    //项目作者信息
    "name": "surging",
    "email": "[email protected]"
  },
  "license": "ISC",    //项目许可协议
  "devDependencies": {    //项目依赖的插件
    "gulp": "^3.8.11",
    "gulp-less": "^3.0.0"
  }
}

如何添加注释

单独开一个约定好的key:value

{
   "_comment": "comment text goes here...",
   "glossary": {
      "title": "example glossary",
      "GlossDiv": {
         "title": "S",
         "GlossList": {
            "GlossEntry": {
               "ID": "SGML",
               "SortAs": "SGML",
               "GlossTerm": "Standard Generalized Markup Language",
               "Acronym": "SGML",
               "Abbrev": "ISO 8879:1986",
               "GlossDef": {
                  "para": "A meta-markup language, used to create markup languages such as DocBook.",
                  "GlossSeeAlso": ["GML", "XML"]
               },
               "GlossSee": "markup"
            }
         }
      }
   }
}
