Libcurl errors with download()

[rafaqz]

Using the download method is broken for me in julia 1.2 on arch linux, using the julia download provided by julialang.org. Basically any command that calls download fails, here the Pkg.build for GR:

(v1.2) pkg> build GR

Does

curl -s -S -g -L -f -o gr-0.44.0-ArchLinux-x86_64.tar.gz http://github.com/sciapp/gr/releases/download/v0.44.0/gr-0.44.0-ArchLinux-x86_64.tar.gz

work if you run it in your terminal? Or

run(`curl -s -S -g -L -f -o gr-0.44.0-ArchLinux-x86_64.tar.gz http://github.com/sciapp/gr/releases/download/v0.44.0/gr-0.44.0-ArchLinux-x86_64.tar.gz`)

in Julia?

I think the system curl always worked fine. And download just fixed itself somehow, now working in atom and the terminal after a few weeks of being broken - I can't replicate the above error, not sure what changed it may have been restart after a system update a few days ago.

[stevengj]

Closing as not reproducible, then.

[rafaqz]

This occurs when the bash PATH or environment is somehow broken, as was happening for me when using julia in tmux. It works fine without tmux.

I can reliably produce that now, but it's a large surface area to work out exactly what is broken, besides the terminal environment somehow affects finding libcurl.so

[stevengj]

Yes, on Linux we require on the curl in the PATH. If this is broken, then download will break.

Eventually it would be good to eliminate this dependency (#27043).
