Javascript 带有laravel的Vue js警告消息

我使用的是Laravel5.4和vuejs 2。我没有得到响应，但控制台中有一些错误。请帮助我解决这些错误。它给出了类似于 [Vue warn]：挂载的挂钩和类型错误：无法读取属性“get”。 我在下面提到了错误消息。我使用

npm install

和

npm vue资源安装了软件包

Friend.vue

<template>
    <div class="container">
        <div class="row">

            <div class="panel-body">
                I'm an example component!
            </div>
        </div>

    </div>
</template>

<script>
    export default {

        mounted() {

            this.$http.get('/check_relationship_status/' + this.profile_user_id)
                    .then((resp) => {
                        console.log(resp)
                    })
        },
        props: ['profile_user_id'],

    }
</script>

错误消息是：
