uni_from表单相关组件Cannot read property '__global' of null atObject.value [as getSystemInfoSync]

我是使用了表单相关组件，不知道是什么原因，请求帮助这个是有关getSystemInfoSync搜索结果 在表单提交后还有警告：[pages/my/Feedback] Some selectors are not allowed in component wxss, including tag name selectors, ID selectors, and attribute selectors.(./uni_modules/uni-load-more/components/uni-load-more/uni-load-more.wxss:65:29)
[pages/my/Feedback] Some selectors are not allowed in component wxss, including tag name selectors, ID selectors, and attribute selectors.(./uni_modules/uni-easyinput/components/uni-easyinput/uni-easyinput.wxss:62:31) 下面是源vue <template>
