In Julia, How do you check, list, update your packages?

Question

I'm wondering if there are utility commands in Julia that perform simple package management operations, such as:

• List a single or all packages installed
• Upgrade a single or all packages installed
• Remove a package or all packages
• Clean up package remnants

These are commands that I frequently use in yarn or homebrew for example and I was wondering if there were equivalents in Julia?

Solution

using Pkg
Pkg.update()
Pkg.status()
Pkg.rm("PackageName")

This is all in the Julia manual.

Nitpicking, but since this seems to be what the user is after, technically the "upgrade" command is more the process of doing a Pkg.update(), Pkg.build(), and possibly triggering a re-precompilation for the affected packages so that they're ready to use.

Thanks! I should have thought to look in the manual! It simply did not occur to me after a quick Google search for "check installed Julia packages" didn't turn up much.

The julia manual is a surprisingly useful document. I used R for years and got into the habit of googling instead of using the manual, but in Julia it really is the first-resort reference.

This is no longer valid in v1.0. At least Pkg.installed()
