I bought one board from Aliexpress and I just recieved it and in my way to try it a got an error when compiling the example code from the library.

Which version of the Arduino esp32 package are you using?
That is the esp32 support package installed through Arduino Board manager.
Make sure it is not the v3.0.0 version, which is in its alpha release.
