for webapp projects built with vue-cli, everything in Android and ios is normal and can be browsed normally in the development environment, but only Android can run after packaging and launch, and all phones under ios11 are not allowed. Opening is a blank, the so-called white screen. Excuse me, how did this come from? Many netizens on the Internet said that it was caused by webpack-dev-server, and I also dropped to 2.7.1 version, but it still didn"t work, so please help me solve the following, thank you! Attached: have a happy life!
