JS：Https.request错误ReferenceError：未定义okhttp3

Question

我遵循此https://github.com/gethuman/nativescript-https

安装：tns plugin add nativescript-https 编写此代码：

public output() {
    Https.request({
      url: 'https://xxx.xxx.x.x/output?pass=1&out1=1',
      method: 'GET',
      headers: {
          'Authorization': 'Basic ZWx1c3VhcmlvOnlsYWNsYXZl',
          'x-uuid': 'aHR0cHdhdGNoOmY',
          'x-version': '4.2.0',
          'x-env': 'DEVELOPMENT',
      },
  }).then(function(response) {
      console.log('Https.request response', response)
  }).catch(function(error) {
      console.error('Https.request error', error)
  })
    }

命令：tns run 显示这个：
