uview-plus 报错 “Cannot read property ‘mpMixin‘ of undefined”_cannot read property 'mpmixin' of undefined

错误原因：

该错误出现在“uview-plus\components\u-calendar\header.vue”文件内，错误原因是mixins中mpMixin,mixin无法通过$u的方式进行获取。

解决方法：

 1.导入 mpMixin,mixin

	import mpMixin from '../../libs/mixin/mpMixin'
	import mixin from '../../libs/mixin/mixin'

2.修改mixins的值

mixins: [mpMixin,mixin],

此时效果：

	import mpMixin from '../../libs/mixin/mpMixin'
	import mixin from '../../libs/mixin/mixin'
	export default {
		name: 'u-calendar-header',
		mixins: [mpMixin,mixin],
		props: {
			// 标题
			title: {
				type: String,
				default: ''
			},
			// 副标题
			subtitle: {
				type: String,
				default: ''
			},
			// 是否显示标题
			showTitle: {
				type: Boolean,
				default: true
			},
			// 是否显示副标题
			showSubtitle: {
				type: Boolean,
				default: true
			},
		},
		data() {
			return {
 
			}
		},
		methods: {
			name() {
 
			}
		},
	}
