我先编写了一个欢迎页面然后编写了一个容器在容器上设置了一个监视器，但是在我点击的时候把报错页面未定义未发现报错信息如下：thirdScriptError 
sdk uncaught third Error 
page is not defined 
ReferenceError: page is not defined

    Page[pages/welcome/welcome] not found. May be caused by: 1. Forgot to add page route in app.json. 2. Invoking Page() in async task.
    
    百度搜索说是我app.json页面顺序排错了，经更改仍然报错，更改如下：   
 "pages":[       
 "pages/welcome/welcome",       
 "pages/index/index",      
  "pages/powerdata/powerdata",   
     "pages/powercontrol/powercontrol",       
 "pages/location/location"
              ],
              
        或者完全关闭在重新启动微信小程序开发者工具，我是先关闭程序在重启电脑，仍然无用报错。求大神指点，代码如下：

welcome.js
page({
  onTapJump: function (event) {
    wx.redirectTo({
      url: "../index/index",
      success: function () {
        console.log("jump success")
      },
      fail: function () {
        console.log("jump failed")
      },
      complete: function () {
        console.log("jump complete")
      }
    });
  }
})
