Package Manager is missing on the Window menu.

The Window menu doesn't show the Package Manager when you open a project imported from 2018.1 by the first time. To have access to the Package Manager you must close the project and open it up again. Also the second time you open the project Unity complaints that it was saved with and older version which is false since you just opened with the current version.

 

I installed 2018.1.0b13 manually (outside the hub) and 2018.2.0b2 from the hub 0.16.0.

 

Thanks Leonard, is good to know!

 

I am just getting started with Unity and also have this problem. No Package Manager entry in the Window menu. I just upgraded to 538p2. I see no way of getting it to display. I have tried loading old projects and creating new empty ones. No difference.

 

Package Manager was introduced in Unity 2017.2 as far as I know. Earlier versions of Unity do not have this feature.

 

It isnt available in the LTS versions either, are you sure it was 2017 it was introduced in? I thought 2018 was earliest?

 

2017 introduced the backend (i.e. you may be able to put stuff in manifest.json - didn't try it)
2018 introduced the UI

 

I just upgraded to b4 and I've got the same problem. Unfortunately my manifest.json looks like this:

Code (CSharp):

1. {
2.   "dependencies": {}
3. }

The window is available in a new project. Is there any other way I can get the window to appear?

 

I have a similar problem, in that the window doesn't appear for existing or new projects; I've reported it as a bug and I'll post an update here if I receive any news.

 

I've received a reply, it seems I have some files missing from my installation which should be in folder C:\Users\user_name\AppData\Local\Unity\cache\packages\packages.unity.com\ (not sure why yet). I'll attach screenshots of the relevant folders and what they have got in them in case anyone else has the same issue.

In the meantime, I'm going to install Unity on another PC and if it works and all the files are there I'll try copying them over to the PC with the issue and see if that fixes the problem

 

I do have the packages, which makes sense, because I do see the project in another window. Guess it's time for me to submit a bug report as well.

 

The installation on the other PC did have all the files, and after copying them to the original PC the problem is fixed.

This doesn't explain what caused the original issue, but it's a workaround at least.

Yours must be a different problem though, but hopefully a bug report will get things sorted for you

 

@LeonhardP I'm having the same problem on Mac OSX Unity v2018.1.1f1. I have moved a project from Windows to the Mac to compile up, but the project won't start because of missing package manager.

I thought about manually copying them from my PC to the Mac, but have no idea where they go on the Mac. There is no package-manager-ui entry in the project manifest so I can't remove that as suggested earlier.

I have tried a complete re-import to no avail.

The Package manager shows up on a newly created project. I have tried on direct launch of Unity and via the Unity Hub. They both come up the same.

I'm at a loss.

Any help would be much appreciated.

Hi @maximeb_unity

Just tried your suggestion, but it is still coming up with the same message.

Yes, definitely using 2018.1.1f1.

Best,

Justin

 

That's odd. I have Package Manager v1.9.6 running on the PC. I replaced it with the one you suggested and it appears to be working. If I change it on the Mac will it still work on the PC with version 1.8.8?

 

Thanks for your help it is working again, but wonder how the 1.9.6 version got on my PC in the first place if 1.8.8 is the current version.
