My Tex code works super good in overleaf and TexMaker, but once it is uploaded to a journal platform (submission procedure), it requires all the packages used.
I didn't find the forest.sty package. I searched over CTAN repository, I found many packages for forest by their names don't match the needed file (i.e, forest.sty).
Where can I find this package ?
Thanks
Since you're apparently able to run the file locally (based on the mention of TeXmaker), that means you likely have it on your system. In TeXmaker, there's a button at the bottom of the screen Messages/Log. Click on that and you'll see a transcript of your LaTeX run. You can scroll through that and near the top, you'll see where the file is loaded from.
That's the easy part. The hard part, is whether the journal requires all the external packages. Because forest is a TikZ extension and will load a few dozen TikZ and pgf files as well. I'm guessing that the journal is being overly cautious in their requirements and you could probably leave out any of the CTAN packages from your submission and obey the letter of the law for their process by sending forest.sty alone, but ultimately the journal production staff would have to be the ones to make that call.
forestpackage. It's source is located here. You'll have to compileforest.insin order to generateforest.sty(details - possible duplicate); for this you'll need a local installation. – Werner Aug 09 '21 at 23:50
