老师,不知道为什么,这个UUID库生成不了UUID,我的代码如下:
import {ref, onMounted, computed, getCurrentInstance} from 'vue'
import { v4 as uuidv4 } from 'uuid'
export default {
name: 'flyBox',
setup() {
const uuid = uuidv4()
let width = ref(0)
let height = ref(0)
let path = computed(() => `M5 5 L${width.value - 5} 5 L${width.value - 5} ${height.value - 5} L5 ${height.value - 5} Z`)
onMounted(() => {
const instance = getCurrentInstance()
width.value = instance.ctx.$refs.container.clientWidth
height.value = instance.ctx.$refs.container.clientHeight
})
return {
path,
uuid
}
}
}报错如下:
TypeError: crypto.randomFillSync is not a function
ps:
我的版本已经和老师的一致了。8.2.0,还是生成不了。

同学你好,crypto模块的主要功能是加密解密,会在打包资源文件中自动导入并使用,你把项目代码上处一下,我在本地帮你定位一下问题吧072024-03-25
