角度构建-不匹配的选择器：%

Question

当我运行执行npm run build的ng build -c production时，构建将按预期完成。但是命令提示符中将包含以下警告：

Warning: 303 rules skipped due to selector errors:
  0% -> Unmatched selector: %
  20% -> Unmatched selector: %
  53% -> Unmatched selector: %
  40% -> Unmatched selector: %
  43% -> Unmatched selector: %
  70% -> Unmatched selector: %
  80% -> Unmatched selector: %
  90% -> Unmatched selector: %
...

如何解决这个警告？

Answer 1

经过搜索，我发现角是消除对IE 11的支持。

解决这一问题的方法有两种：

1. 从特德普尔特或.browserslistrc中删除对IE11的支持

last 1 Chrome version
last 1 Firefox version
last 2 Edge major versions
last 2 Safari major versions
last 2 iOS major versions
Firefox ESR
not IE 11 # Angular supports IE 11 only as an opt-in. To opt-in, remove the 'not' prefix on this line.

• not是必不可少的。

1. 通过编译您的项目以通过多填充降低ECMAScript添加支持。您可以遵循这篇文章中提到的步骤。

Answer 2

您是否可以尝试将以下内容放入".browserlistrc“文件中。该文件位于项目的根目录中。

最后一个Chrome版本 最后一个火狐版本 最后2个边缘主要版本 最后2个Safari主要版本 最后2个iOS主要版本 Firefox ESR IE 11

这曾经帮助我修正了错误。
