Bootstrap 4 beta 3使用angular-cli抛出错误

在将我的引导程序包更新到4.0.0-beta.3时,我遇到了以下错误.如果我错过任何东西,请告诉我.它正在与beta.2合作

"@angular/animations": "^5.1.2",

您可以使用Bootstrap 4 beta 3,但首先在node_modules / bootstrap中编辑bootstrap.json / package.json：

“browserslist”: [
“last 1 major version”, <—– delete this line
“>= 1%”, <—– delete this line
“Chrome >= 45”,
“Firefox >= 38”,
“Edge >= 12”,
“Explorer >= 10”,
“iOS >= 9”,
“Safari >= 9”,
“Android >= 4.4”,
“Opera >= 30”
],

看起来在浏览器列表2.4中添加了最后n个主要版本语法,并且在7.0版中将autoprefixer更新为browserList的版本2.

因此,7.0以上的任何版本的autoprefixer都应该有效.

更新autoprefixer也应该为您完成工作.
