webpack连接mysql

Question

在 webpack 中连接 mysql 运行之后给出如下报错，按照提示下载以来也无效

Module not found: Error: Can't resolve 'buffer' in 'C:\company\api_test_script_manager\node_modules\readable-stream\node_modules\safe-buffer'

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:

    - add a fallback 'resolve.fallback: { "buffer": require.resolve("buffer/") }'
    - install 'buffer'

If you don't want to include a polyfill, you can use an empty module like this:

    resolve.fallback: { "buffer": false }
