Unity package manager error opening 2D Game kit

Unity Engine
1

Hello,
I am totally new to using unity, downloaded recently the 2D game kit proyect to try it but when i open it i get the message that an error has ocurred when resolving packages,says the proyect has invalid dependencies following a unity proyect manager route. It also tells me to re-import the proyect or to manually modify a temp file called “manifest.json”
Anyone has any idea what i can do to fix this and do the tutorial proyect??
thanks a bunch and sorry to bother.

Go to your folder where you’ve saved the kit demo project.

There should be:

  • Assets
  • Library
  • Packages

You want Packages. Inside, there’s a file called “manifest.json”. Open this, and add the line it tells you that you need. Do so - and be sure to follow the same format of the existing lines. If that doesn’t work, copy paste the error here so we can look at it.

Lo-renzo, I tryed your steps and got nowhere. Here is the error I got when I imported 2D Game Kit:

An error occurred while resolving packages:
Project has invalid dependencies:
com.unity.package-manager-ui: Package [com.unity.package-manager-ui@2.1.2] cannot be found

The console is telling me to: A re-import of the project may be required to fix the issue or a manual modification of C:/Users/Rich/Desktop/New Project/2D Game Kit/Packages/manifest.json file.

I went over to the project folder where manifest.json file is and openned it up in notepad.

I saw the “com.unity.package-manager-ui”: “2.1.2” file there. I not sure if I need to delete this or keep it there since later it might have problems. Do you have any solutions or maybe you have deleted it and it worked?

I deleted: “com.unity.package-manager-ui”: “2.1.2”, in the notepad and the problem was solved. I’m crossing my fingers it doesn’t have problems later looking for that tag.
