i try search for my issue but no new my gulp js is // copy css and minify from development to deployment 我尝试搜索我的问题,但没有新的gulp js //复制CSS并从开发到部署最小化
gulp.task("compress-css", () => {
return gulp.src( pathGo+"css/**/*.css")
.pipe(cssmin().on('error',function(e){
console.log(e)
}))
.pipe(gulp.dest('testing_folder/css1'));;
});
notice i used proxy 通知我使用代理
i find the issue that css file is't writing correctly ( Files ready from framework ,the framework can work with this files ). 我发现css文件无法正确写入的问题(文件已从框架准备就绪,框架可以与此文件一起使用)。 i try move my files away from framework css files and run gulp so gulp is running and minify correctly thanks for all
我尝试将文件从框架css文件中移开并运行gulp,以便gulp正在运行并正确缩小,感谢所有
I wish my answer help you if the same issue faced you 如果遇到同样的问题,希望我的回答对您有所帮助
I encountered the same problem, the final discovery is that I quote the font file syntax error. 我遇到了同样的问题,最后的发现是我引用了字体文件语法错误。
before 之前
@import url(../font/PingFangSC.ttf);
after 后
@font-face {
font-family: 'PingFang SC';
src: url('../font/PingFangSC.ttf');
font-weight: normal;
font-style: normal;}
why CSS not provide syntax for compilation checks? 为什么CSS不提供编译检查的语法?
