Conda not found after upgrading to macOS Catalina

Question

You can find the entire anaconda3 environment in a shortcut link named 'Relocated Items' on your desktop. It appears as though the upgrade to Catalina does not allow the Conda environment to be installed under a user directory now likely having to do with the new system volume move to a read-only partition.

This issue has been opened as far back as June 10th, I am a little disappointed that it was not resolved before the Catalina upgrade came around.

There is a solution that appears to work without losing your environment, see this link: https://github.com/ContinuumIO/anaconda-issues/issues/10998#issuecomment-539215005

From the link:

1. Copy the folder anaconda3 located in Relocated Items to /Users/myname/

2. Open Terminal

3. Enter: export PATH='/Users/myname/anaconda3/bin:$PATH'

4. Enter: conda init zsh

Anaconda has published a blog post on the issue. There seem to be two main options:

1. Reinstallation: for now shell installer only (you’ll need to wait for the new installer if you rely on the GUI instead).

2. Repair (experimental): will allow you to fix your old installation and keep all of your old environments

You can check the Anaconda website for further information.

None of the existing answers worked for me but this one does.

1. Download anaconda's self-contained prefix replacement tool at https://repo.anaconda.com/pkgs/misc/cpr-exec/cpr-0.1.1-osx-64.exe and make it executable:

   curl -L https://repo.anaconda.com/pkgs/misc/cpr-exec/cpr-0.1.1-osx-64.exe -o cpr && chmod +x cpr
   

2. Move your anaconda3 folder from Relocated Items to your home folder: ~/anaconda3.

3. Fix your folder using the following command:

   ./cpr rehome ~/anaconda3
   

4. Re-run conda init to fix your conda shell command:

   source ~/anaconda3/bin/activate
   
   conda init
   

If you are using zsh,replace the last command with:

conda init zsh

If you are using zsh, conda installer adds a conda init script at the end of your ~/.bash_profile file. You should copy it and paste into your ~/.zshrc file.
