Updating base #553

Closed gah-bo closed 4 months ago

gah-bo commented 4 months ago

Comment:

I can't find a clear/recent source on this. I am simply wondering if it's OK for me to do

mamba update mamba followed by mamba update --all on my base environment to keep it "up to date". I've seen places state the base Python should not be updated, for example, so this is very confusing to me.

Note: I understand I should not mamba install X on base, and I have not done that - I have an env per project. I am simply asking if/how I should keep my base env up to date...Sorry for this very trivial question

mamba update mamba
mamba update --all

should be fine

If you want to remember a single command, from whatever environment you are in.

mamba update mamba --yes --prefix $(conda info --base)
mamba update --all --yes --prefix $(conda info --base)

Honestly, I just call

mamba update --all --yes

periodically, however, i treat my environments as disposable, so i don't mind having to periodically fully reinstall miniforge.

python for the base environment shouldn't matter so much.

I would stick with python 3.10, but newer is fine too.

Python 3.9 might be too old for fresh installs.

If you have a minimal python 3.8 environment, you can sometimes have some luck with

mamba install python=NEW_PYTHON_VERSION

to force it to update.
