Hi, here is a zsh session using flox activate:

You can notice 2 things:
-
flox activate ends up doing adding default more than once on the path (not a big deal but maybe worth cleaning up)
-
flox activate -e haskell does not change the PATH to add haskell first but . <(flox activate - haskell) does
I don’t know if that can be fixed so that flox activate -e does the right thing or if the documentation needs to fix (or if it depends on something that’s shell-specific).
Thanks @etorreborre for the bug report. Regarding #1 you’re absolutely correct that flox will activate the same environment multiple times and we’ll be fixing that shortly. As for #2 I’ve not seen that bug before - the latest available for download is 0.0.6-r52 and I’m not able to reproduce the issue with that version.
I’ll keep looking at the code and try to reproduce the issue but in the meantime can you send:
- the exact flox version that you used to create that example
- the output of
flox --debug activate -e haskell
- the contents of
/Users/etorreborre/.cache/flox/profilemeta/etorreborre/manifest.toml immediately after running the above command
Many thanks!
Here you go:

I tried the updated installer but unfortunately I got an error with no additional explanation (on mac/intel)
Did you originally use the installer to install Nix & flox or did you install flox on top of an existing installation of Nix? If the former then can you please send me the recent lines from /var/log/install.log by email or Discord? We’ll get the upgrade working before returning back to the flox activate issue. Thanks as ever for your patience!
Progress - I’ve been able to reproduce the problem. Currently contemplating the correct way to fix it but hope to get something out for you by the end of the day. As an added bonus the bugfixed version will add these additional features:
- doesn’t warn about missing environment when activating default
- makes
flox activate verbose with -v flag
- avoids leaking
FLOX_PATH_PREPEND variable to subshells
- adds activated environments to
PS1 prompt in subshells
- throws an error when attempting to activate the same environment twice
- in verbose mode is more verbose about setting of
ZDOTDIR for zsh

Alas I didn’t quite get it to you yesterday but I’ve now got a new version I think you’ll find works much better. It’s available for installation from the flox channel with the command flox install flox.flox-prerelease, or if you’ve installed this package before (I think you have) then flox upgrade flox.flox-prerelease will upgrade it to the latest version:
[flox] λ flox upgrade flox.flox-prerelease
upgrading 'evalCatalog.x86_64-linux.stable.flox-prerelease' from flake 'github:flox/floxpkgs/31debf7003dbf261548fb2adfb53e1f364b1d78a' to 'github:flox/floxpkgs/bc9047d4e629f21270010d8b03de8b84ef19487a'
this derivation will be built:
/nix/store/w4551d4xa2gg7nl1ykqiyhfmaypavr5b-flox-prerelease-0.0.6-r54.drv
building '/nix/store/w4551d4xa2gg7nl1ykqiyhfmaypavr5b-flox-prerelease-0.0.6-r54.drv'...
[flox] λ flox --version
Version: 0.0.6-r54
[flox] λ
Also, my apologies for providing the wrong upgrade instructions earlier; I forgot that you had moved over to the flox-prerelease package installation. When installing flox over an existing Nix installation you have to install flox to a profile or run it in a nix-shell, after which you can install and maintain flox with flox. 
I am trying to upgrade but now, when I start a shell, I don’t even have a flox version to start with (possibly that’s the result of the failed mac installer execution?).
You wrote that I need to install flox to a profile. I tried to follow the nix instructions on “Install flox” but flox is still not available when I start a shell session. What should I do?
Making sure there was no nix-daemon in the background and re-running the mac installer eventually did it for me. Back on track!

excellent. Please let us know if you run across any issues with r54. Michael plans to release it later this week and announce it in our new “announcements” discourse category
