Need some help here! I was trying to create a environment named bioinfo, but error just every where. Newbie here, try to call for help. What should I do to fix it?

Hi cypiao, welcome to the community. Since your command creates an environment with only python 3.8 in it, rather than anything specifically related to bioinformatics (other than the name), you might have more luck with a forum more dedicated to general conda troubleshooting, rather than bioinformatics forum. You could try the resources listed here:https://docs.conda.io/en/latest/help-support.html

this is a really weird error that frankly should not happen, the package that was not found is called

package_name

that means something got really messed up there.

here is what I found googling:

https://stackoverflow.com/questions/35224186/conda-create-environment-fails-with-error-no-packages-found

https://stackoverflow.com/questions/42026224/packagenotfounderror-when-creating-new-conda-environment

see if any of those help? Did you run conda config by any chance as one of the posts mention?

thanks man, problem solved!
