autoprefixer Didn't work ？

[FeSeason]

In file webpack.base.conf.js has code

    loaders: utils.cssLoaders({ sourceMap: useCssSourceMap }),
    postcss: [
      require('autoprefixer')({
        browsers: ['last 2 versions']
      })
    ]
  }

But in Vue component when i use css3 it really not add a prefix ?

<template>
    <div class="taskLog">
        <div class="test">TaskLog</div>
    </div>
</template>
<style scoped>
    .test{
        transform: scale(1.2);
    }
</style>

transform doesn't need a prefix in any of 2 last version of browsers: http://caniuse.com/#search=transform
Next time, please, open the issue in the relevant template repo. Thanks 🙂

   loaders: utils.cssLoaders({ sourceMap: useCssSourceMap }),
    postcss: [
      require('autoprefixer')({
        browsers: ['ie >=9']
      })
    ]
  }

Doesn't work. Doesn't generate any prefixes.
