I follow conda_PR_545, conda issues 4221 and still not working on Ubuntu.

After downloading conda.fish from here, and mv it to anaconda3/bin/.

Add "source /home/phejimlin/anaconda3/bin/conda.fish" at the end of ~/.config/fish/config.fish.

conda activate spark_env
Traceback (most recent call last):
File "/home/phejimlin/anaconda3/bin/conda", line 6, in 
sys.exit(conda.cli.main())
File "/home/phejimlin/anaconda3/lib/python3.6/site-packages/conda/cli/main.py", line 161, in main
raise CommandNotFoundError(argv1, message)
TypeError: init() takes 2 positional arguments but 3 were given

or

activate spark_env
Error: activate must be sourced. Run 'source activate envname'
instead of 'activate envname'.

Do I miss something?

As of fish 2.6.0 conda 4.3.27: the following steps may change as issue is addressed

update config

Take note of your conda's location

conda info --root
/Users/mstreeter/anaconda    # this is my <PATH_TO_ROOT>

Add line to ~/.config/fish/config.fish

 source <PATH_TO_ROOT>/etc/fish/conf.d/conda.fish

update convention

Typically you'd run the following from bash

source activate <environment>
source deactivate <environment>

Now you must run the following from fish

conda activate <environment>
conda deactivate <environment>

issues

so after doing this I'm not able to set fish as my default shell and have it still work properly with conda. Currently, I must first enter my default shell, and enter fish and the shell works as expected. I'll update this after I find out how to get it working completely without the need to explicitly choose fish each time I log into my terminal

    i just tried this and have no problem with having fish as my default shell. after creating a new shell session, my default conda env is correctly activated and shown. – K.-Michael Aye Sep 27 '18 at 23:20
  • This works for me but not fully: after I activate a conda env it still points to my system python instead of the conda env's python. Any ideas how to address this? – jjs Apr 04 '19 at 22:38

  • Perfect! Updating the config is all that is needed. – Adam Erickson May 18 '19 at 01:30

If you follow https://github.com/conda/conda/issues/2611, the steps are (from start):

[root@6903a8d80f9b ~]# fish
root@6903a8d80f9b ~# echo $FISH_VERSION 
2.4.0
root@6903a8d80f9b ~# bash Miniconda2-4.3.11-Linux-x86_64.sh -b -p /conda
root@6903a8d80f9b ~# source /conda/etc/fish/conf.d/conda.fish
root@6903a8d80f9b ~# conda activate root
root@6903a8d80f9b ~# conda create -yn fishtest                              (root) 
Fetching package metadata .........
Solving package specifications: 
Package plan for installation in environment /conda/envs/fishtest:

#
# To activate this environment, use:
# > source activate fishtest
#
# To deactivate this environment, use:
# > source deactivate fishtest
#

root@6903a8d80f9b ~# conda activate fishtest                                (root) 
root@6903a8d80f9b ~#                                                    (fishtest) 
root@6903a8d80f9b ~# conda deactivate fishtest                          (fishtest)

    WOW! So magic, it's working! I just add "source (conda info --root)/etc/fish/conf.d/conda.fish" to my config.fish and it's working! Thank you, I almost spent all day on this environment setting. – Jim Mar 18 '17 at 15:10
  • my answer is basically your answer Nehal, it seemed as if the details were buried in your answer though, so I wrote what I did at my level – Marc Oct 21 '17 at 18:14
  • the only question i have, is, why are you working as root. ;) – K.-Michael Aye Sep 27 '18 at 23:21
  • For SO answers, I just spawn a new container and I am usually root in them :) – Nehal J Wani Sep 28 '18 at 04:14

Adding conda's bin directory to PATH isn't recommended as of conda 4.4.0 https://github.com/conda/conda/blob/master/CHANGELOG.md#440-2017-12-20

All you need to do is adding source <path-to-anaconda>/etc/fish/conf.d/conda.fish to config.fish.

    Since Conda v4.6.0, you should just be able to run `conda init` and it will adjust `config.fish` for you. – merv Apr 05 '19 at 00:42
