如上，webpack打包后，运行出现fs.readFile is not a function。是哪里配置有问题吗？

另 import * as fs from 'fs'改为const fs = require('fs')，报错 __webpack_require__(...) is not a function

感谢大佬帮忙。困扰好几天了。

备注：以上在浏览器中测试，实际build产物运行在electron渲染线程中，同样的问题。

刚刚看了下fs这个包，好像被删除了，换一个类似的包，或者不用它试试正常不。
This package contained malicious code and was removed from the registry by the npm security team. A placeholder was published to ensure users are not affected in the future.
此包包含恶意代码，已被npm安全团队从注册表中删除。发布占位符是为了确保用户将来不受影响。
