I’m using Unity 5 and getting these error messages every time I open Unity or enter play mode:
Failed to load package manager
Failed to load package manager
UnityEditor.Modules.ModuleManager:InitializePlatformSupportModules()
Failed to load package manager
UnityEditor.Modules.ModuleUtils:GetAdditionalReferencesForUserScripts()
Not sure if it’s related, but I was writing editor scripts before these errors started happening. The errors happen whenever I open Unity now, even if I start a new project.
Edit: Reinstalling fixed this, but I’m wondering if anyone else has gotten the errors & has a solution that doesn’t involve a reinstall
I am using the Free Personal edition and I am getting same errors. On all my Projects. Tried update License in the unity license manager… still same problem.
I have this error on Linux with the 2017.3 version. It’s not necessarily related to a license issue (anymore). In my case, it’s more likely a file permission issue. I installed Unity in /opt as root, then launched is a a normal user. Unity starts, but the console is spammed with lots of “package dependency failed to load” nonsense and my scripts do not compile (the compiler reports missing references to every single unity engine assembly).
I copied the whole unity directory somewhere (cp -r /opt/Unity-xxx /home/myuser/somedirectory) as root then gave it to my normal user (chown -R myuser:myuser /home/myuser/somedirectory/Unity-xxx). Launching Unity from the copied, user-owned folder works as expected.
This is obviously not a ideal solution since it forces you to copy the gigantic Unity folder once per user ; I played around a bit with the file permissions and another solution is to keep the original root-owned folder and make everything in it executable. The real, good solution would probably to make contact with the package maintainers at Unity and ask them to check which file exactly needs to have its permissions fixed, but I’m too lazy to do it right now
I´ve got this error after upgrading unity, from 5.0.1f to 5.0.2f. Seems like this new version doesn´t support library UnityEngine.UI features. Anyone knows something about it ?
It seems like you are having issue with your unity license. You are using wrong license for wrong version of unity or you are using wrong crack for wrong unity version. For example you have installed unity 5.1.0f3 but you using the license/crack of unity 5.1.0p1. Which cause “Failed to load Package Manager”. Hope that will be helpful for you.
