还要安装一下postcss-import （npm install postc-import --save-dev）
{
test: /\.css$/,
use: [
'style-loader',
'css-loader?importLoader=1',
{
loader: 'postcss-loader',
options: {
plugins: [
require('postcss-import') (),
require('autoprefixer')({
browers: ['last 5 versions']
})
]
}
}
]
}
),
应该是版本的问题，你试试这样可以不，这个是对css文件的，我这边可以运行
npm install cross-env
npm install webpack-dev-server
