Can't run Anaconda in MacOS terminal

Question

I installed Anaconda on MacOS. I tried to run the conda command in terminal, but I got the following error message:

****/Users/rodalbert/.anaconda/navigator/a.tool ; exit;
/Users/rodalbert/.bash_profile:export:3: not an identifier: 2018.12
➜  ~ /Users/rodalbert/.anaconda/navigator/a.tool ; exit;
/Users/rodalbert/.anaconda/navigator/a.tool: line 1: syntax error near unexpected token `('
/Users/rodalbert/.anaconda/navigator/a.tool: line 1: `bash --init-file <(echo "source activate /Users/rodalbert/anaconda3;")'
[Process completed]****

I can't find the problem. Does someone know what to do in this case?

Answer 1

It seems like you're using Zsh.

Before executing any command from within Anaconda Navigator, try opening your Terminal app and switching shell to bash: chsh -s /bin/bash then restart terminal.

After you're done with Anaconda, switch back to Zsh: chsh -s /bin/zsh then restart terminal.

I used MohammadChavos 's solution, then conda can run on the terminal.

cd /path/to/anaconda/bin
./conda init zsh
or:
zsh conda init zsh

My case: cd opt/anaconda3/bin, then run: ./conda init zsh
