Hello, I`m new into the Processing, and have a major problem for more than one scripts.
Here is the error:
**No library found for org.processing.wiki.triangulate**
**Libraries must be installed in a folder named ‘libraries’ inside the sketchbook folder (see the Preferences window).**
**The package “org.processing” does not exist. You might be missing a library.**
can somebody help me to find and install the libary ?
Thanks in advance.

Hi! welcome to the forum!
maybe this thread - specifically the web archive link helps?

if not it would be helpful if you post the code that you’re working on 🙂
