resetting conda channel priorities

Question

I am having issues with conda. After running commands such as:

conda install -c /my_conda_channel numpy --offline --override-channels

the default conda channel has now become 'my_conda_channel' so that each subsequent package from this channel supercedes the default channel, which is not what I want. I did the former just for testing purposes.

How do I reset the channel behaviour?

Answer 1

Change the order from ~/.condarc so that defaults the first channel as

channels:
  - defaults
  - conda-forge

and add this line to it

channel_priority: true

or run the following code in command-line

conda config --set channel_priority true

then again run

conda update --all

Good Luck

Answer 2

Go to your home directory and open .condarc in an editor. Go to channels and edit the priority:

channels:
  - defaults
  - my_conda_channel

Now defaults will be preferred over my_conda_channel. You can also delete my_conda_channel.

Answer 3

Another option would be to move your channel to the bottom of the priority list.
Run the command....

conda config --append channels my_conda_channel

You should get a response like this...

Warning: 'my_conda_channel' already in 'channels' list, moving to the bottom

Verify...

conda config --get channels

Which should give you something like...

--add channels 'defaults'   # highest priority
--add channels 'my_conda_channel'   # lowest priority
