Hi, I meet this problem today ,not sure what happened, I can run the same code yesterday, and today just keep meeting this problem with hdbscan , can you please help me with it?

Start by reproducing the pip build failure for hdbscan and inspect the reported hdbscan/_hdbscan_linkage.pyx errors, especially the missing dist_metrics.pxd and DistanceMetric declarations. Confirm the relevant dependency and build configuration from the repository before determining whether a successful wheel build can be verified.
