error with LiquidCrystal library

What does the Compiler want me to do about this error:

"Multiple libraries were found for "LiquidCrystal.h" ?

It means exactly what it says. It found multiple copies of the library. Get rid of the duplicates.

You have duplicate files, while this is not allowed in the places where you have them.

How could this happen?

Did you possibly try to install a different LiquidCrystal library or a LiquidCrystal_I2C library?
If yes: Which one? And: search your harddisk for all occurences of file name "LiquidCrystal.h! How many do you have?

Read the rest of the error messages and see a message which says " using xyz library".
Is that the library you want to use ?

If it is - do nothing, unless the "multiple libraries" message is offensive to you.

If it is not - delete if from your system.
