The generated code contains 'async/await' because this module is using "external script".

版本2.7.1
emp init 两个项目 react_base react_app
target 使用emp init 默认的es5

react_app中运行会提示以下信息，要怎么解决？

compiled with problems:
WARNING in external "microHost@http://127.0.0.1:8001/emp.js"
The generated code contains 'async/await' because this module is using "external script".
However, your target environment does not appear to support 'async/await'.
As a result, the code may not run as expected or may cause runtime errors.
