1. Antd version 3.11.2 has been upgraded, and Select components that use antd have alarms
. 
2. The local code is as follows:
<Select
showSearch
style={{ width: 200 }}
placeholder="Select a person"
optionFilterProp="children"
onChange={this.handleChange}
onFocus={this.handleFocus}
onBlur={this.handleBlur}
filterOption={(input, option) => option.props.children.toLowerCase().indexOf(input.toLowerCase()) >= 0}
>
<Option value="jack">Jack</Option>
<Option value="lucy">Lucy</Option>
<Option value="tom">Tom</Option>
</Select>3. Hope to remove the alarm and display normally
