Error: noCacheKeyConformance(Swift.Array<SystemPackage.FilePath.Component>)

[yingguqing]

Hi! I am trying to cross compile for ubuntu x86_64 and arm64 architectures. I followed the steps on the readme and cloned the repo and ran swift run swift-sdk-generator make-linux-sdk.

However, I am seeing this output:
