Copying Project.toml doesn't install pakages (and throws error)

I have a Project.toml file that I copy to new machine’s environment/v1.1 folder and run Pkg.resolve() to install all packages and dependencies. Is this the right way in Julia v1.1?

In case it’s the right way, it break randomly with error:

ERROR: Unsatisfiable requirements detected for package Redis [0cf705f9]:
 Redis [0cf705f9] log:
 ├─possible versions are: [0.0.1-0.0.2, 0.1.0-0.1.1] or uninstalled
 ├─restricted to versions * by an explicit requirement, leaving only versions [0.0.1-0.0.2, 0.1.0-0.1.1]
 └─restricted by julia compatibility requirements to versions: uninstalled — no versions left

To circumvent the problem , I used the old way of creating REQUIRE file and creating a startup file like below.

using Pkg

function Pkg_update()
    pkgs = readlines(joinpath(homedir(), ".julia", "REQUIRE"))

Pkg.add(PackageSpec(name="Redis", rev="master"))

based on Does 0.7 support REQUIRE?

Strangely, the second process works and end up generating the exactly the same Project.toml file in environment/v1.1 as the one I copied (but didn’t work)

Can someone please tell me what’s the right way of using Project.toml?

It just seems that Redis doesn’t support julia versions over 0.7.

It apparently does now, but hasn’t been tagged yet (it hasn’t seen a tag since 2016!). Once that’s done this should work without the above script.

But master version of Redis repo does work with Julia v1.1
