调试vue发现错误，提示方法没有定义，在IDE工具提示是要注意选择正确的选项：

代码：

 new Vue({
        el: '#blist',
        delimiter: ['[[', ']]'],
        data: {
            message: 'hi vueeee',
        },
        method: {
            getbooks: function () {
                console.log(123)
                var url = "http://127.0.0.1:8000/booklist/books_view"
                axios.get(url).then((response) => {
                    console.log(response)
                }).catch((error) => {
                    console.log(error)
                })
            }
        }
    })

异常如下：
[Vue warn]: Property or method “getbooks” is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data

原因：关键词拼写错误，pycharmt提示不小心选错
应是：methods，delimiters

pycharm提示多个，注意选择正确的：
