Invalid package cache - file '...\bugpoint.exe' is missing on win-64

Solution to issue cannot be found in the documentation.

Issue

My project apparently won't build on Windows without llvm-rc installed, so I have arrived at this package for that reason.

To reproduce:

PS C:\Users\User> micromamba create -n Bug -c conda-forge

That seems like a micromamba error.

You can try upgrading your mamba version, and if the problem persists, raise an issue in https://github.com/mamba-org/mamba

mamba-org/mamba#170

This looks to be an issue with lack of symlink support on Windows.

[wolfv]

@stellarpower symbolic links generally require admin privileges on Windows. I think packages should - in general - avoid symbolic links on Windows.

You can turn on developer mode or run the terminal in admin mode: https://stackoverflow.com/a/58048888

It looks like this package contains a couple of symbolic links, e.g.

    {
      "_path": "Library/bin/llvm-strip.exe",
      "path_type": "softlink",
      "sha256": "86e1709c98deeb65768678a89960bb559d85f9dd157d4438659bd527b6c9bec3",
      "size_in_bytes": 4131328
    },

I don't know where they are pointing, though, and how easy / hard it is to turn them into hard links.

[wolfv]

looks like these are the symbolic links:
