Add conda to path in fish

Question

~> conda install pandas
fish: Unknown command 'conda'

I understand that I need to add conda to PATH, but no matter what combinations of commands I tried, I could get it to work. I still get the above error.

Answer 1

1. Install Anaconda

2. Run conda init fish

3. In your ~/.config/fish/config.fish you should see some lines added by Anaconda:

    #>>> conda initialize >>>
    # !! Contents within this block are managed by 'conda init' !!
    eval your/path/to/anaconda3/bin/conda "shell.fish" "hook" $argv | source
    # <<< conda initialize <<<
   

4. Restart the terminal. You should see now Anaconda activating the (base) environment. Check running echo $CONDA_PREFIX the loaded environment is pointing in the right place.

Hope this helps. Let us know if you still have problems

Answer 2

Where is conda installed? If it's in ~/anaconda/bin, then you want to run this:

Try set -U fish_user_paths ~/anaconda/bin $fish_user_paths

Modifying PATH is discussed in the fish tutorial

Hope that helps!

Answer 3

you can do it in one Line and don't bother yourself (MacOS and Linux)

/(your conda installation path)/bin/conda init fish

your condo installation usually in '/Users/- your UserName -/anaconda3'

if someone want to know about install fish, best way is Homebrew. after brew install fish you mush add fish to supportable shells in /etc/shells. and then with chsh change default shell to fish. if it's not clear ask in comment!

Answer 4

I assume you have 'config.fish'(create if you don't have) file in ~/.config/fish/ directory. Now add the following to the file 'config.fish':

set  PATH /home/<user>/anaconda3/bin $PATH

Then save the file. Close the current terminal (fish shell) and open again. Now you can use Anaconda's python.

To check: run python3 and you will see:

 Python 3.7.1 (default, Dec 14 2018, 19:28:38)
 [GCC 7.3.0] :: Anaconda, Inc. on linux
 Type "help", "copyright", "credits" or "license" for more information.

To use conda activate env command

Enter this command on your fish shell:

conda init fish

Now, restart the terminal and use any conda command you like.

Answer 5

If running conda init fish prevents fish from running (as it did for me), it would be better to just remove whatever conda has added to the ~/.config/fish/config.fish file and just add the following line.

source /Users/yourname/anaconda3/etc/fish/conf.d/conda.fish

assuming Anaconda is installed in /Users/yourname/

Answer 6

Conda command will not work until you run the conda init fish. but on fish terminal it will also not work.

1. Open Fish/bash terminal

it will open the bash inside fish, incase you opened fish

$ bash

2. then init the conda

conda init fish

You are done
