Question

我正在按照Flutter教程来创建Flutter应用。首先，使用flutter命令def execute(self, context): if self.bq_cursor is None: self.log.info( "Beginnging Execution." ) hook = BigQueryHook( bigquery_conn_id=self.bigquery_conn_id, use_legacy_sql=self.use_legacy_sql, delegate_to=self.delegate_to) conn = hook.get_conn() self.bq_cursor = conn.cursor() self.bq_cursor.run_query( self.sql, destination_dataset_table=self.destination_dataset_table, write_disposition=self.write_disposition, allow_large_results=self.allow_large_results, flatten_results=self.flatten_results, udf_config=self.udf_config, maximum_billing_tier=self.maximum_billing_tier, maximum_bytes_billed=self.maximum_bytes_billed, create_disposition=self.create_disposition, query_params=self.query_params, labels=self.labels, schema_update_options=self.schema_update_options, priority=self.priority, time_partitioning=self.time_partitioning ) self.log.info( "Executed: %s" % self.sql ) def on_kill(self): super(BigQueryOperator, self).on_kill() self.log.error( "Failed to Execute: %s" % self.sql ) if self.bq_cursor is not None: self.log.info('Canceling running query due to execution timeout') self.bq_cursor.cancel_query()进行初始化。然后执行flutter create myflutter得到一些flutter run解决依赖关系错误，当我访问gradle时显示405网络错误，然后我将dl.google.com文件更改为访问正常的网站访问，我仍然失败。以下代码是我的配置： android \ build.gradle：

bulid.gradle

错误消息：

flutter doctor -v

可能是我的版本错误？或其他配置错误？

Answer 1

像这样更改网址：

....
    repositories {
        mavenCentral()
        maven { url 'https://maven.aliyun.com/repository/google/' }
    }
.
.
.
allprojects {
    repositories {
        mavenCentral()
        maven { url 'https://maven.aliyun.com/repository/google/' }
    }
}

请原谅我的英语。我不能用中文发布答案。
