I am trying to install Julia dependencies for PYSR and I am getting following message . HOW DO I RESOLVE THIS?

Which operating system are you using? Which Julia version? What is the output of
```julia
versioninfo()
```
?

How did you try do install PySR? Conda? pip? docker?
There is even a forum just for PySR: [MilesCranmer/PySR Q A · Discussions · GitHub](https://github.com/MilesCranmer/PySR/discussions/categories/q-a)

Something is a bit strange. How did you install Julia, Python, and PySR?

Conda install, as it was discussed by MILESCRANMER in GitHub.

Well, from my personal point of view Python on Windows is a nightmare… That’s why I am using Julia on Linux… No such problems. But I understand that you cannot use pure Julia if you want to use PySR…

PySR is a python wrapper for a Julia package, so you definitely can use it without python.

My current understanding is that you used conda to install PySR, which in turn also installed Julia via conda? Did you do this on Linux or Windows?

That doesn’t quite add up because you cannot install PySR via conda on Windows:

oh… there’s an old noarch version.
Could you do a `conda list` for us so we can see what’s going on in the conda environment?

Pip install pysr resolved the issue for Julia Dependencies for PYSR. Thank you @ufechner7

Hello. I am trying to run PySR and getting the same error mentioned in this threat
julia.core.JuliaError: Exception ‘failed to clone from [GitHub - MilesCranmer/SymbolicRegression.jl: Distributed High-Performance Symbolic Regression in Julia](https://github.com/MilesCranmer/SymbolicRegression.jl), error: GitError(Code:ERROR, Class:SSL, Your Julia is built with a SSL/TLS engine that libgit2 doesn’t know how to configure to

Pkg.add([sr\_spec, clustermanagers\_spec], io=stderr)
As Ive read, the solution was found when running pip install pysr, but that is not working for me since when I do this I get that all the requirements are already satisfied.
When I run again, I get the same message
julia.core.JuliaError: Exception ‘failed to clone from [GitHub - MilesCranmer/SymbolicRegression.jl: Distributed High-Performance Symbolic Regression in Julia](https://github.com/MilesCranmer/SymbolicRegression.jl), error: GitError(Code:ERROR, Class:SSL, Your Julia is built with a SSL/TLS engine that libgit2 doesn’t know how to configure to

Any ideas?
Thanks

Also, as Miles Crammer suggested in a Githbs issue /
I think you could get around this by running the following in the Julia REPL. First, hit ] to turn on Pkg mode. Then,
activate @pysr-0.16.3
rm SymbolicRegression ClusterManagers DynamicExpressions
add SymbolicRegression ClusterManagers DynamicExpressions
I did this on my Julia console and got
✗ SymbolicRegression
65 dependencies successfully precompiled in 54 seconds. 10 already precompiled.
7 dependencies errored.
For a report of the errors see `julia> err`. To retry use `pkg> precompile`

How did you install Julia and PySR? From Julia, could you provide the full output of `versioninfo()`?

Could you provide the full output of `err` after precompile?
Also, how did you install Julia?
