Cannot run the example from the documentation about symbolicregression.jl HOT 13 CLOSED

Does this issue go away the second time you open up Julia, and don't write the Pkg stuff?

from symbolicregression.jl.

No, still getting the same error. What's in your environment, maybe I need to have a package I'm currently missing.

Very strange, I will think more about this. Can you try installing a different Julia packages from GitHub?

The required packages are listed here: https://github.com/MilesCranmer/SymbolicRegression.jl/blob/master/Project.toml

And all installed packages in my env are given here:
https://github.com/MilesCranmer/SymbolicRegression.jl/blob/master/Manifest.toml

from symbolicregression.jl.

I have the same probblem:
Pkg.add(url="https://github.com/MilesCranmer/SymbolicRegression.jl.git")
Updating git-repo https://github.com/MilesCranmer/SymbolicRegression.jl.git

from symbolicregression.jl.

Tried it on different julia versions, but with no luck:
1.2: Doesn't install due to unsatisfied dependency on SpecialFunctions
1.3, 1.4, 1.5, 1.6-beta: Same error as before.

from symbolicregression.jl.

Hm, it seems like I was too strict with the [compat] requirements (here), and this is what's creating the installation difficulty. I don't actually use many of the functions from each required packages so I can probably weaken the version requirements a lot.

Sorry for the installation difficulty, will try to fix this tomorrow.

from symbolicregression.jl.

Perhaps the installation problem should have it's own github issue as it's separate from inability to actually run the package.

I've actually managed to run the example when I skipped the activate . and installed and run everything in the main environment.

from symbolicregression.jl.

I updated the [compat] requirements; can you try again?

from symbolicregression.jl.

yes, now it works. Thanks !

from symbolicregression.jl.

It also works in Test2 environment as long as SymbolicRegression is also installed in the main environment.

from symbolicregression.jl.

Awesome!

from symbolicregression.jl.

Isn't it weird though? I'm not a Julia expert, but shouldn't it work just fine without a need to adding it to the main env?

from symbolicregression.jl.

Yeah, this is definitely weird. Let's try again once it's on the general registry, for now, your added instructions are good - thanks.
