QIIME2-2018.11 Installation ResolvePackageNotFound Error

Hi QIIME2 support team,

I have been working to install QIIME2-2018.11, and I keep getting the following error:

conda env create -n qiime2-2018.11 --file qiime2-2018.11-py35-osx-conda.yml

I’ve looked at previous posts and I am for sure using the mac wget link with a mac computer. I also tried uninstalling miniconda altogether and reinstalling it using

bash Miniconda3-latest-MacOSX-x86_64.sh

This appeared to be successful, and I also did “conda update conda” and “conda install wget” before trying to install QIIME2-2018.11 again, but unfortunately got the same error.

I’ve also recently updated my mac to Mojave - would that have anything to do with it, possibly? I’ve never had this issue in the last 1.5 years or so using QIIME until after this update.

I am at a loss here, so thanks for all your help!!

Hey there @hdeel!

I hope not! I am running Mojave right now, too --- all seems to be fine.

Can you run this command and report the results back to us?

conda info

Thanks! :t_rex: :qiime2:

Hi @thermokarst,

Here are the conda info results:

Hmm, everything looks okay there…

I just did another macos install of 2018.11 today and everything worked fine — is it possible that your institution’s network firewall is causing problems?

I am a bit confused about the error message you have pasted, too, because at least one of the versions doesn’t make any sense:

That should read q2-emperor=2018.11.0, so I am not sure what is happening…

How about you do the following:

  • Clean your conda cache (this stays around even if you delete and reinstall conda): conda clean --all
  • Delete the qiime2-2018.11-py35-osx-conda.yml file
  • Start from the beginning of the install doc (download the env fresh).

Sorry I don’t have a better answer for you - keep us posted!

Hi @thermokarst,

So I’m not sure what the problem was, but I’ve got it working! I literally copied the conda create command pasted above into terminal to regenerate the error, and it worked. Maybe I just needed to restart my terminal or something.

Anyway, thanks for your help! Happy QIIME-ing! :dog:
