Usually pretty good. The package management is completely centered around Pkg.jl, which is integrated in the REPL and you can also import it to your program for more advanced scripting. If you don't create an environment, everything is added to the global user library, and if you do create it, it will automatically manage your projects dependency files, and each environment/package can have it's own independent versions of each library (so you don't really have dependency hell issues, but you might end up with more disk space due to multiple versions of the same library, although it will respect semver when keeping multiple libraries). Pkg.jl is based on git/github with a central registry that can I believe it's automatically updated with new packages using bots. The current version also has native supports for automatically deploying binaries and other stuff like datasets, that can be optionally loaded on demand. Most troubles I hear is with more strict enterprise firewall scenarios and perhaps Julia JIT making it compile the libraries every time (though that's not an issue with the package manager).
