How do I remove all my installed packages at once, if possible?

[giordano]

I was talking about not updating, not not precompiling:

What is in your startup.jl?

Here is my updated one. I gave up on updating all packages # Disable updating registry on `add` (still runs on `up`), as it is slow using Pkg: Pkg Pkg.UPDATED_REGISTRY_THIS_SESSION[] = true # use more colors for displaying Pkg conflicts if isdefined(Pkg.Resolve, :CONFLICT_COLORS) append!(Pkg.Resolve.CONFLICT_COLORS, [21:51; 55:119; 124:142; 160:184; 196:220]) end # Setup Revise.jl atreplinit() do repl try @eval using Revise @async Revise.wait_steal_repl_backend() …

But I guess someone may not want to precompile (?)
