[BUG]: Installation failed on Windows: failed to clone from SymbolicRegression.jl

[Nithouson]

What happened?

I successfully installed and used an older version of PySR (0.14.x). As I want to upgrade to the latest version, I uninstalled the existing PySR (via pip) as well as Julia 1.6.1 (I also deleted the ~/.julia directory). Then I installed the latest Julia 1.6.3, and PySR 0.16.3 via pip. When I run the command python -m pysr install, the installation fails repeatedly, with the following Error message: julia.core.JuliaError: Exception 'failed to clone from https://github.com/MilesCranmer/SymbolicRegression.jl, error: GitError(Code:ERROR, Class:OS, failed to send request: 操作超时)' Yet I can manually download the SymbolicRegression.jl repository in web browser, which shows the network connection works well (In addtion, I access Github behind proxy). Any idea how to figure out this? Many thanks!

Hm, this might explain things.

Could you try making a local copy of the PySR repository, and deleting these lines?

https://github.com/MilesCranmer/PySR/blob/2f91f1f3377613949d2a15e5142e6dfef6a5b86c/pysr/julia_helpers.py#L266-L267

Then it should download SymbolicRegression.jl from the Julia package registry instead of GitHub.

This solution works. Many thanks! I will close this issue. By the way, I also tried configuring git to work behind proxy: git config --global https.proxy ... Not sure whether this is also necessary.
