Unable to use Zlib_jll in julia 1.6 (Package Zlib_jll does not have JLLWrappers in its dependencies)

General Usage
1

I’m using Julia 1.6.3, and I get an error if I try to use Zlib_jll or any package that has it as a dependency (eg, CodecZlib or CSV).

Adding the package has a compile error:

(v1.6) pkg> activate Foo
  Activating new environment at `~/Foo/Project.toml`

(Foo) pkg> add Zlib_jll
    Updating registry at `~/.julia/registries/General`

I was under the impression that Zlib_jll was compiled into julia 1.6, so shouldn’t need to be precompiled. Any idea what’s happening?

Update Similar issue happens with MozillaCACerts_jll. I have to remove the existing folder for julia to work.

I think I may have some idea of what’s happening, but don’t understand it fully.
I recently upgraded from julia 1.5.4, and as a result I still had a .julia/packages/Zlib_jll/ folder in place. Once I removed this folder, the errors went away.

So, new question - should julia ignore the packages/ folder if a package is already compiled into the sysimage?

I think Julia 1.6 may use different versions of the packages than Julia 1.5 did.
Have you tried Pkg.resolve(), Pkg.instantiate() and possibly Pkg.update() (e.g. for your Foo packge)?

Yes, they all have the same problem. As long as there exists a Zlib_jll folder under packages, julia 1.6 will not work.
