Unity 2020.2 GUID conflicts, cannot compile

[samanabo]

I'm attempting to install this package through the package manager via a git url in unity 2020.2.7f1.
Once it is added to the package manager I get the following errors:

GUID [9b9b359874c54b8e9968bce99b84b1cd] for asset 'Packages/com.xsduan.hierarchy-folders/Editor/Icon Handling.meta' conflicts with: 'Packages/com.xsduan.hierarchy-folders/Editor/Icons.meta' We can't assign a new GUID because the asset is in an immutable folder. The asset will be ignored.

GUID [d6f29c3d38f5ea94dbfbf44facaeaaca] for asset 'Packages/com.xsduan.hierarchy-folders/Editor/Icon Handling/HierarchyFolderIcon.cs.meta' conflicts with: 'Packages/com.xsduan.hierarchy-folders/Editor/Icons/HierarchyFolderIcon.cs.meta' We can't assign a new GUID because the asset is in an immutable folder. The asset will be ignored.

GUID [7b9019de4b525b349a48678a64d7983a] for asset 'Packages/com.xsduan.hierarchy-folders/Editor/Icon Handling/ReplaceColor Shader.shader.meta' conflicts with: 'Packages/com.xsduan.hierarchy-folders/Editor/Icons/ReplaceColor Shader.shader.meta' We can't assign a new GUID because the asset is in an immutable folder. The asset will be ignored.

There appears to be an error here for each file in the Editor folder of this package.
Is there something I am doing wrong to import this? or perhaps the meta files need to be updated on the repo since the last update?
Let me know how to proceed. Thanks!

There is a PR that fixes the issue but it is not merged yet: #18.

You can install the package using the following git URL: https://github.com/SolidAlloy/unity-hierarchy-folders.git#guid-duplication-fix

Really sorry, totally forgot about this.

Yup, should be fixed now.
