修复date-fns-tz导入失败问题

在执行yarn build打包node项目时，出现以下错误：

[vite]: Rollup failed to resolve import "date-fns/_lib/cloneObject/index.js" from "node_modules/date-fns-tz/esm/formatInTimeZone/index.js".
This is most likely unintended because it can break your application at runtime.
If you do want to externalize this module explicitly add it to
`build.rollupOptions.external`
error during build:

原因是本地缓存不完整或出现错误，无法找到对应的依赖文件，打开该文件后，发现文件内容只有正常文件的一部分，怀疑是使用的npm镜像没有完整文件内容。可通过运行以下命令重建本地缓存，重新尝试打包即可成功：

yarn cache clean
