2.3.0以后默认启用自定义组件模式，该模式性能更高，但可能不支持部分复杂事件写法，建议如果复杂的话，重新封装一个事件方法

2.2.2版本启用启用自定义组件模式编译都没问题

<template>
  <view class="content">
    <view class="text-area" @click="true ? test().then(() =>{ cLog() }) : cLog">
      <text class="title">{{ title }}</text>
    </view>
  </view>
</template>

<script>
    export default {
        data() {
            return {
                title: 'Hello'
            }
        },
        methods: {
            test() {
                return Promise.resolve()
            },
            cLog() {
                console.log('test')
            }
        }
    }
</script>

这样又能编译
