PublicLibraryPaths does not exist in the current context

"PublicLibraryPaths" is not a built-in variable or function in any programming language that I'm aware of. It's possible that it's a variable or function specific to the code that you're working on. Without more context, I can't provide a definitive answer, but it's possible that you need to define or import the "PublicLibraryPaths" variable or function before you can use it in your code. Alternatively, it's possible that you have a syntax error or typo somewhere in your code that is preventing the variable or function from being recognized.
