Question

我想知道如何使用EQCSS（https://github.com/eqcss/eqcss）设置Vue-cli-3。

我已经创建了一个项目，并使用“ npm install eqcss --save”安装了eqcss，程序包现在存在于node_modules /中。我的main.js如下所示：

import Vue from 'vue';
import eqcss from 'eqcss';
import App from './App.vue';
import router from './router';

Vue.use(eqcss);
Vue.config.productionTip = false;

new Vue({
  router,
  render: h => h(App),
}).$mount('#app');

然后我尝试使用以下方法在默认的App.vue中应用EQCSS：

<template>
  <div id="app">
    <div id="nav">
      <router-link to="/">Home</router-link> |
      <router-link to="/about">About</router-link>
    </div>
    <router-view/>
  </div>
</template>

<style lang="scss">
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
}
#nav {
  padding: 30px;
  a {
    font-weight: bold;
    color: #2c3e50;
    &.router-link-exact-active {
      color: #42b983;
    }
  }
}

// eqcss
@element #nav and (min-width: 500px) {
  :self {
    color: #000;
  }
}

</style>

这给我带来以下错误：

 ERROR  Failed to compile with 1 errors                                                                                                                                                                                                                          5:03:10 PM
