Install library for arduino using library manager


I managed to install some libraries for arduino project using the library manager of platformio. However for some library such as TTS.h ( text to speech), the library manager returns a reply as"Not Found".
Is there a way to install the libraries using the manager. Thanks.


I would like to extend this to ask if someone can create a tutorial about uploading libraries.
I have not found the library manager too useful and I have a lot of libraries on my PC that I want to drop into the global folder.
some are ZIP, others not.


I’ve just added this library to our repository. See

Next time you can use in your platformio.ini
