Installation issue

Please note I have signed up to your online course in January and so am trying to get everything installed before then, and have run into an issue with installation (see below for details).

I apologise if I have missed something simple - I am new to this. I am trying to install the command line version but also want to know if I should install the studio version too - ready for the course.

Thanks you - your help is much appreciated.
Emma.

  • Have you searched for the problem on the forum? It is rare that we see a new question asked, so make sure you do your homework before asking for us to commit our time to helping you.
    YES - I have to confess, I am new to this and so don’t particularly understand the responses - sorry! I am using a windows machine and have installed miniconda3, but it seems to fail at the installation step. I have seen you have recommended WSL to someone else - but they didn’t say if this had worked so wanted to check.

  • Have you reviewed the QIIME 2 Forum Glossary?
    YES

  • Version of QIIME 2 you are running, and how it is installed (e.g. Virtualbox, conda, etc.)
    NONE yet - trying to do that via miniconda3 on a windows machine

  • What is the exact command or commands you ran? Copy and paste please.
    conda env create -n qiime2-2020.11 --file qiime2-2020.11-py36-linux-conda.yml --verbose

  • What is the exact error message? If you didn’t run the command with the --verbose flag, please re-run and copy-and-paste the results.

Hi @emma.marczylo, welcome to the community! Thanks so much for the detailed error report, this is really helpful.

The issue here is that we don't support direct-installation on Windows, rather we support Windows installations through several "virtual machine" environments: Docker, VirtualBox, or WSL. Here is an excerpt from the docs:

If you have access to the WSL, that is the direction I suggest you go!

Regarding the January 2021 FAES workshop - we will actually be providing you with access to a compute cluster with QIIME 2 pre-installed on it, so no rush on getting this installed, you won't need it for the sake of the workshop.

Keep us posted!

Matthew,

Thank you so much for your swift reply – and sorry that I am going over old ground. I very much appreciate your response.

I did the introductory course at the World of Microbiome conference – and very much enjoyed it. I am looking forward to exploring QIIME2 further in Jan. It is a relief to know that if I can’t get things sorted before then that I will still be able to fully participate.

Thanks again,

Emma.
