第三方库：
https://github.com/google/blockly
需要引入两个js文件
blockly_compressed.js
blocks_compressed.js
使下边的代码正常运行

<template>
    <div id="lesson1">
        <h1>挑战1</h1>
        <hr>
        <div id="blocklyDiv" style="height: 480px; width: 600px;"></div>
        <xml id="toolbox" style="display: none">
            <block type="controls_if"></block>
            <block type="logic_compare"></block>
            <block type="controls_repeat_ext"></block>
            <block type="math_number">
                <field name="NUM">123</field>
            </block>
            <block type="math_arithmetic"></block>
            <block type="text"></block>
            <block type="text_print"></block>
        </xml>
    </div>
</template>

<script>
    Vue.use(Blocks)
    var workspace = Blockly.inject('blocklyDiv', {
        toolbox: document.getElementById('toolbox')
    });
</script>

@oyljerry

这样还是不行

<template>
    <div id="lesson1">
        <h1>挑战1</h1>
        <hr>
        <div id="blocklyDiv" style="height: 480px; width: 600px;"></div>
        <xml id="toolbox" style="display: none">
            <block type="controls_if"></block>
            <block type="logic_compare"></block>
            <block type="controls_repeat_ext"></block>
            <block type="math_number">
                <field name="NUM">123</field>
            </block>
            <block type="math_arithmetic"></block>
            <block type="text"></block>
            <block type="text_print"></block>
        </xml>
    </div>
</template>

<script>
    import Blockly from '../../public/blockly_compressed.js'
    Vue.use(Blockly)
    import Blocks from '../../public/blocks_compressed.js'
    Vue.use(Blocks)

    var workspace = Blockly.inject('blocklyDiv', {
        toolbox: document.getElementById('toolbox')
    });
</script>

import xxx from yyy.js
Vue.use(xxx)

import {setCookie, getCookie, delCookie} from '../../assets/js/cookie'

使用：

setCookie('ruleForm', JSON.stringify(this.ruleForm), 10000)
console.log(JSON.parse(getCookie('ruleForm')))
