IOException: Permission denied for CacheOutputDirectory on Mac

[Tunied]

Hi,

I'm running into an issue when trying to install packages via NuGetForUnity on macOS.

The installation fails with the following error:

IOException: Permission denied

Which occurs at:

Directory.CreateDirectory(CacheOutputDirectory);

Looking into the source code, I see that DetermineCacheOutputDirectory() resolves the cache path like this:

var localApplicationDataFolder = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData);
return Path.Combine(Path.GetFullPath(localApplicationDataFolder), "NuGet", "Cache");

On macOS, this resolves to:

/Users/eran/.local/share/NuGet/Cache

(eran is my username.)

However, this directory doesn't exist by default, and attempting to create it programmatically fails due to insufficient permissions.

To resolve the issue, I had to manually:

• Create the directory
• Grant read/write permissions to everyone on that folder

I'm not sure whether this is a macOS-specific issue or something more general, but it might be worth mentioning in the documentation or installation guide. Hopefully this can help others running into the same problem.

Thanks!

Thank you for sharing the solution.
However, I did that and granted permission using the following command, but I still get the error.

sudo chmod 777 ~/.local/share/NuGet/Cache

sudo chmod 777 ~/.local/share/NuGet/Cache

the path should be

/Users/$YOUR_USER_NAME/.local/share/NuGet/Cache

Thanks. I am not sure what I was doing wrong, but it worked finally. I also restarted Unity, I am not sure if that has anything to do with the fix.
