How to get Conda and Virtualenv to work on mac OS Catalina?

Question

I previously had Conda running smoothly on Mojave, but I\'ve found that the upgrade to Catalina moves the \"anaconda3\" folder to your Desktop > Relocated Items > Security >

Answer 1

I have the same problem, and this work for me : My solution:

1. Copy your anaconda3 from Relocated Items folder
2. Paste in User/YourUserName
3. Open conda file in anaconda3/bin with the editor and edit the first line #!/anaconda3/bin/python to #!/Users/YourUserName/anaconda3/bin/python
4. Save it and run conda file
5. Open Terminal
6. Run this : export PATH=''/Users/YourUserName/anaconda3/bin:$PATH"
7. Run conda init zsh

Answer 2

Technically this is reinstalling anaconda, however, I restored all my conda envs so, hopefully this is an acceptable solution!

Here is how I got it working on Catalina as of a few minutes ago (now using z-shell): - Verified the existence of "Relocated Items" directory on my desktop and the "anaconda3" directory and its contents inside - Navigated into the envs directory under "anaconda3" and left the finder window open (see screenshot)

THEN:

• opened new Terminal (z-shell)

• ran (this installed to /usr/local/anaconda3):

  brew cask install anaconda

• after installation was successful I opened my ~/.zshrc file (for my z-shell aliases) and added the following line:

  export PATH="/usr/local/anaconda3/bin:$PATH"

• saved my ~/.zshrc file, then reloaded with:

  source ~/.zshrc

• to verify conda command works now, I ran:

  conda env list

• for me, this showed a base env and that was it

• then open Finder to the new envs location: open /usr/local/anaconda3/envs/.

• I dragged (moved) all my old envs into the new envs folder, and then ran:

  conda env list

And all my old envs are back! :)

• updated my PyCharm interpreter / env paths to reflect the new locations of these envs (had to restart PyCharm after, but now it works!)
• DONE
