Omnisharp installation error

[hwhite85]

Hi All,

I'm trying to install omnisharp ls and keep getting "Cannot write exec wrapper to "omnisharp" because the file already exists". I've removed the existing omnisharp folder in the data directory, but this had no effect.

Does anyone know what might be causing the issue?

Thanks

If you've manually tried to clean up things in Mason's directory it may have "corrupted" the installation if not all related artifacts were removed. Try installing again with the --force flag, :MasonInstall --force

Tried it with no luck. It looks like it is failing on the "Registering bin links" line:

Hm there seems to be an issue with the package itself on case-insensitive file systems actually. mason-org/mason-registry#1478 should fix this, (once merged run :MasonUpdate and try installing again)

That did it. Thanks!
