如何关闭现代模式

[ideayuye]

Version

5.0.0-rc.3

Environment info

由于vue-cli build会默认进入modern模式，导致要编译两次。本来每次编译要耗时几分钟，现在需要十几分钟。有没办法关闭现代模式，直接编译一个兼容老版本浏览器的版本。

Steps to reproduce

vue-cli-service.js build

What is expected?

关闭现代模式

What is actually happening?

You can opt-out this behavior by appending a --no-module flag to the build command. vue-cli-service build --no-module will only output the legacy bundles that support all target browsers (loaded via plain <script>s).
