Can't install Polars and DuckDB on windows 11

But with add Polars I get the error I posted above.
When I tried the same on linux (WSL 2), I got the error

ERROR: The following package names could not be resolved:
 * Polars (not found in project, manifest or registry)
   Suggestions: Solaris Colors Polymers Pilates Poptart PolyChaos Monads Dolang Jolab Posets Folds Tonari Colab Losers Peaks

On Windows 10 and Julia 1.11.1 at least I got the same error message as you got on WSL 2. Assuming you’re referring to

GitHub - Pangoraw/Polars.jl: :bear: Julia wrapper around the polars library

the problem just seems to be that this package is not registered. Luckily you can simply use

(@v1.11) pkg> add https://github.com/Pangoraw/Polars.jl

which works fine for me.

For DuckDB (v1.1) I got precompilation errors, both on Julia 1.10.4 and 1.11.1. This seems to be a known issue:

Help Using DuckDB

I get an error when trying to use DuckDB. Is it my setup, something I might be doing wrong, or possibly a package issue? julia> using DuckDB Precompiling DuckDB Info Given DuckDB was explicitly requested, output will be shown live ERROR: LoadError: could not load symbol “duckdb_vector_size”: Thank you for any help you might give a newbie hobbyist.

In this topic there are also some (links to) suggested workarounds. Using DuckDB v1.0 via

(@v1.11) pkg> add DuckDB_jll@1.0 DuckDB@1.0

(first rm or remove v1.1 if it is installed), I did not run into any problems.
