Hi,

I was trying to update the dependencies and was following this.

> I was inquiring earlier about upgrading Sage 9 to work with PHP 8.0 and just found a public github fork of sage which does just that. I saw other inquiries about the same thing, so I thought I would write a message here for those who are looking for this: Here is the changes in composer.json (not the full file, just the bit with changes): "autoload": { "psr-4": { "App\\": "app/" } }, "repositories": [ { "type": "vcs", "url": "https://github.com/jeh5256/sage-installe…

I am working on the localhost Xamp on windows and used this composer.json file.

After running Update Composer, I am getting this error.

```

Can anyone please help me?

The reason is the case sensitivity of the directories names, see this issue and the fix:

I've had to bite the bullet and revert back to the 9.0.0-beta.4 version of controller to get around this. But I thought I'd post here because I have now tried setting up a completely fresh install of bedrock/sage with no development work, all I've done is change controller to version 2, run `composer update` and install ACF Pro. I renamed app.php to App.php and changed it's namespace to App\Controllers. However I still get this error on my staging server:
