Upgrading version of DataFrames (stuck at 0.21.8)

New to Julia
1

Hi, this must be a very silly thing, but I haven’t updated Julia in quite some time, and I can’t remember how to do it properly. Basically I just installed Julia 1.6.1, and then, since I would like to keep the same packages I used to have, I copied the Manifest.toml and Project.toml files to the new ~/.julia/environments/v1.6 directory.
First time I go into Julia, I get some errors, but I just to ] build ; ] update and upon restarting Julia all looks fine and no errors, but for some reason I get stuck at version 0.21.8 of DataFrames. What am I doing wrong?

Thanks

Do ] add DataFrames@1.1

Thanks, but is there any reason why I have to specify the version, instead of by default getting the latest one? (Is this only for DataFrames for some reason?)

By the way, I cannot get that to work:

Your second post answers your first - you have unsatisfiable requirements in your environment. Don’t just dump all your packages into the default environment, instead create a new environment for every project you work on with only the packages you actually need. This will minimize dependency conflicts.

If you do:

]activate --temp

]add DataFrames

you will get 1.1 installed in the temporary environment.

OK, thanks. I was doing it that way since it was the suggested way in some other post to migrate from a Julia version to another one, but it looks like it is perhaps not the best way to do it. So I just removed the whole environments/v1.6 directory, started all over, installing just the packages that are missing when I run my scripts, and all looks fine now.
Cheers,
