After installing miniconda, when I am putting the command
conda create -n qiime1 python=2.7 qiime matplotlib=1.4.3 mock nose -c bioconda

following error is coming. How to come out? Please rectify the issue.

Good afternoon!

Welcome to the Qiime 2 forums. Let me see if I can help answer your question.

While I couldn't find the old 1.4.3 version of matplotlib on conda, I did find it on GitHub. Maybe you could install it from there:

Keep in mind that this version of matplotlib is over 4 years old, so it might be time for an upgrade! Have you considered using Qiime 2? :qiime2:

Hello,
I'm trying to install qiime1 (I have already worked on Qiime2 having no issued during installation and running process) using the command:
conda create -n qiime1 python=2.7 qiime matplotlib=1.4.3 mock nose -c bioconda

however I get the error:
Collecting package metadata (repodata.json): done
Solving environment: failed
PackagesNotFoundError: The following packages are not available from current channels:

I ran the commands you suggested and I got again an error:
Collecting package metadata (current_repodata.json): done

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
Specifications:

  • conda=4.6.14 -> python[version='>=2.7,<2.8.0a0|>=3.7,<3.8.0a0|>=3.6,<3.7.0a0']

Your python: python=3.8

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

How could you you run the commands without getting this error? What might be causing this?

Thanks in advance,
Mania

acitvate the environment

conda activate qiime1

Install the python

conda install python=2.7 -c bioconda

and then install qiime1

conda install qiime mock nose -c bioconda
