Stuck at Solving Environment on Anaconda

Question

I am running OSX Catalina. After downloading Anaconda, I'm having trouble downloading external packages. I tried in both the GUI and the terminal, but the process keeps getting stuck at "Solving environment".

I understand creating a new environment can be a workaround, but I would rather fix the issue at hand.

Any ideas?

Answer 1

The following steps may work to resolve the issue.

conda config --remove channels conda-forge
conda config --add channels conda-forge

if it doesn't work then try this

conda update conda

if nothing works try seeing this github solution, it worked for many.

Answer 2

use this:

conda config --set channel_priority strict

pay attention that it is channel_priority and not priority_channel

Answer 3

running

conda config --set channel_priority flexible

worked for me

Update, still ran into some issues so I found Mamba, and oh my god my life changed conda is the worst package manager ever

all my issues were solved when I used mamba

# install mamba
conda install -n base conda-forge::mamba

# use mamba
mamba install pandas

Answer 4

Please, check that python is actually listed in environment.yml or conda create -n your_environment --file requirements.txt python=3.7. Otherwise, conda is traversing all versions of python available. Check that Python is listed.
