Hi~
I use jill in my MacBook and I want to know how to uninstall the specified version of Julia? By manual manipulation or something else?

Thanks

Fu

To completely uninstall julia installed by jill on macOS:

  • delete the julia folder in install_dir, e.g., /Applications/Julia-1.6.app
  • optionally remove the symlinks in symlink_dir, e.g., ~/.local/bin/julia-1.6

So for instance, run the following codes if you want to remove Julia-1.6:

rm -rf /Applications/Julia-1.6.app
rm ~/.local/bin/julia-1.6
# maybe also
rm ~/.local/bin/julia-1
rm ~/.local/bin/julia

Thanks~
The path ~/.julia also have some Julia files, whether to remove?

~/.julia is used to store Julia packages, precompiled files, environments and etc. If you meant to uninstall Julia and don't plan to use Julia anymore, then yes, you can also remove that folder. jill itself doesn't touch this folder.

Yep, I know that.

  • For example, I use jill to install 2 versions eg. Julia-1.5 and Julia-1.6, and I use both of them. Duing to some reasons, I need to uninstall the julia-1.5 and all the packages of it, and don't break environment of Julia-1.6.
  • I found some all packages will be stored in ~/.julia; so how to distinguish those packages between different versions of Julia.

Duing to some reasons, I need to uninstall the julia-1.5 and all the packages of it, and don't break environment of Julia-1.6.

The following codes should be sufficient:

rm -rf /Applications/Julia-1.5.app
rm ~/.local/bin/julia-1.5

I found some all packages will be stored in ~/.julia; so how to distinguish those packages between different versions of Julia.

All Julia packages are installed in ~/.julia/packages/ in version-agnostic manner; whether a specific package version is used depends on the environment you're using. For instance, ~/.julia/environments/v1.6/Manifest.toml specifies all julia package versions. There isn't ~/.julia/packages/v1.6 stuff. Thus you don't need to worry about this at all.

If you want to cleanup some spaces, you can try pkg> gc in Pkg mode. Or if you insist, another way is to manually remove ~/.julia/packages folder and then pkg> instantiate to rebuild it.
