Uninstalling a Library in arduino.app?

Projects Programming
1

Hi, is it possible to uninstall an installed library from within the arduino.app (Mac in this case)? Or how should I proceed to achieve this?

Hi @krischu. By "arduino.app", do you mean the Arduino IDE? If so, which version of the Arduino IDE are you using?

Welcome to the forum

Do you mean a library that is installed on a Mac PC ?

If so, then delete the library folder from the libraries folder of your sketchbook folder

Thanks. Arduino IDE, yes. 1.8.19
I found it. Went into ~/Documents/Arduino/libraries and deleted the directory carrying the name of the package to remove. Unless there is a direct way to do this from within the IDE.

Version 2.0 of the IDE has functionality to uninstall libraries

Ah, thanks, interesting. But I don't see a Version 2.0 for download. Does the arduino.app have an "in app" update feature?

7

What is the "app" that you are referring to ?

Is it the IDE running on the PC or something else ?

The download links are here under the "Future Version of the Arduino IDE" section of the Software page:

Yes, but not advisable.
Ctrl-Click Applications/Arduino.app and select "Show Package Contents". Then drill down into Contents/Java/libraries and delete the folder containing the built-in library you want to eliminate.

Also, navigate to Library/Arduino15 in your home directory. Drill down to Library/Arduino15/packages/arduino/hardware/avr//libraries to see if there is an updated version of the library you want to eliminate.

Yes, I mean the arduino IDE

11

Exactly which library do you want to delete and why ?

I wanted to delete nanoforth 1.4.4 which I installed using the library manager. It conflicts with the nanoforth.ino when the latter is installed from github.

13

That would be in Documents/Arduino/libraries/nanoFORTH

I'm surprised that the one from github is not installed in the same directory.

@johnwasser : I don't quite get your comment. I cloned the github repo somewhere in the file system, loaded the nanoFORTH.ino file from there into a project. Tried to compile it. Got an error. Then I used the library manager to install nanoFORTH. And of course this one got installed into ~/Documents/Arduino/libraries/nanoFORTH.

Then I got a doubly defined symbol from the linker and the question arose, how to deinstall the nanoFORTH package again.

Or is there a way to install from github directly in the arduino IDE? Did you mean this?
