    There are multiple modules with names that only differ in casing. This
    can lead to unexpected behavior when compiling on a filesystem with
    other case-semantic. Use equal casing. Compare these module
    identifiers:
    * C:\cygwin64\home\waysolutions-soft\curso\nodejs\react\node_modules\React\cjs\react.development.js
        Used by 1 module(s), i. e.
