ERR_PACKAGE_PATH_NOT_EXPORTED with version > 2.1.0

If I install mysql2@2.2.5 and run the following:

"use strict";

const mysql = require("mysql2");
const ClientFlags = require("mysql2/lib/constants/client.js");

It throws:

internal/modules/cjs/loader.js:518
  throw new ERR_PACKAGE_PATH_NOT_EXPORTED(basePath, mappingKey);
  ^

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './lib/constants/client.js' is not defined by "exports" in /Users/VisualStudio/node_modules/mysql2package.json

With mysql2@2.1.0 there is no error.

Not sure if its the cause but note the missing slash at the end of the error: node_modules/mysql2package.json

@chrisveness I’d like to avoid promoting access to ./lib as “official” solution to any problem and rather think of some api accessible from top level import

I personally prefer full path as to me it’s a bit more deterministic ( if you have require('./path/a/b)` you can change what is acutually required bu adding different files - folder “b” with index.js, b.json etc etc. Also might be a bit more performant ( it’s a tiny bit, but when you have 1000 of files required at startup bu dependencies of dependencies that can add up )
