I recently updated my MacOS to Catalina, and now I have the infamous "zsh command not found: conda" when I enter "conda" in my terminal. I've read a number of solutions, and the easiest for me to try was to reinstall Anaconda in my home directory (specifically, the 2019.10 version of the installer installs in Users/myname/opt/anaconda3), as suggested by the folks at Anaconda here.

Well, I did just that and it did not solve the problem. What am I missing?

    Conda installs scripts for bash, but not zsh. The easiest way is to fire up bash, and run `conda init zsh` (from bash) this will put the appropriate code in you zsh profile (you'll need to start a new terminal session). – Mark Jan 21 '20 at 02:34

    Thank you for your help. I switched my user account to bash and found that conda ran immediately without additional work. I guess that's because conda runs on bash. But I did the zsh switch as you suggested, and the conda command works now on zsh. – Ashton T. Sperry Jan 22 '20 at 19:55

From the Anaconda install docs:

In order to initialize after the installation process is done, first run source <path to conda>/bin/activate and then run conda init.

However,

If you are on macOS Catalina, the new default shell is zsh. You will instead need to run source <path to conda>/bin/activate followed by conda init zsh.

I tried in Macbook M1 Air with the following command.

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

Example:

/Users/<username>/opt/anaconda3//bin/conda init zsh

Then restarted the terminal and executed the command

conda activate base

It worked perfectly

Source command is taken is from here

After installing miniconda on macos, we need to initialize the zsh. Different from the command ~/miniconda3/bin/conda init for the legacy bash, we need to add zsh in the end, i.e., ~/miniconda3/bin/conda init zsh. Then restart the terminal.
