   $ node --version
     v22.5.1
   

2. Install e118-iin-list:

   $ npm install e118-iin-list
   

3. Require the package:

   $ node --eval "require('e118-iin-list')"
     node:internal/modules/cjs/loader:635
        throw e;
        ^
   
     Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined

Change the exports path from import to ..
