Info

The Conda Runtime Configuration file, an optional .yaml file that allows you to configure many aspects of conda, such as which channels it searches for packages, proxy settings, and environment directories

Note

This file is not created by default, you will need to create it. In the example below we use vim to create it.

Info
Code Block
# In your home folder:
[salexan5@mblog1 ~]$ vim .condarc
envs_dirs:
  - /project/arcc<project-name>/salexan5<username>/conda/envs

pkgs_dirs:
  - /project/arcc<project-name>/salexan5<username>/conda/pkgs

always_yes: true
Info

  • The final option “Choose the yes option whenever asked to proceed, such as when installing.“
