在工具上模拟更新。

文档是这样写的，分开监控：updateManager.onCheckForUpdate和updateManager.onUpdateReady分开。亲测没问题

const updateManager = wx.getUpdateManager()

updateManager.onCheckForUpdate(function (res) {
  // 请求完新版本信息的回调
  console.log(res.hasUpdate)
})

updateManager.onUpdateReady(function () {
  wx.showModal({
    title: '更新提示',
    content: '新版本已经准备好，是否重启应用？',
    success(res) {
      if (res.confirm) {
        // 新的版本已经下载好，调用 applyUpdate 应用新版本并重启
        updateManager.applyUpdate()
      }
    }
  })
})

updateManager.onUpdateFailed(function () {
  // 新版本下载失败
})
