Failed to Create On-rep-seq virtual environment

[AlexGaithuma]

When I run the command: conda env create -n On-rep-seq -f On-rep-seq.yaml I get the following....

Can you please check your conda version with: conda --version The version should be >=4.6 If not, try updating it with: conda update conda

[AlexGaithuma]

Thanks. The command: conda --version gives: conda 4.3.16

I ran the command: conda update conda then conda --version still gives me: conda 4.3.16

I even tried conda install -c conda-forge conda and conda install -c anaconda conda The NoPackagesFoundError still persists..

conda --version still gives me: conda 4.3.16

Thanks lauramilena3

I finally solved it. I uninstalled Anaconda2 and installed Anaconda3 conda --version: 4.7

Creating the environment worked!

[lauramilena3]

Great! I made some edits on the repo this morning to add a newer version of Snakemake. Please update the repository with "git pull" Then, create the environment as you did before. (conda env create -n On-rep-seq -f On-rep-seq.yaml)
