Errors in the installing of PICRUSt2 under QIIME 2 2020.8 version

[LXE_Soil_ecol (Xi-En Long)]

Hello everyone!
I would like to intall PICRUSt2 in the latest QIIME2 following the instruction of this website (Installation · picrust/picrust2 Wiki · GitHub). I had tried both from bioconda and source, and got different error messages. Here is the detail error information:

1. from bioconda:
   run
   conda create -n picrust2 -c bioconda -c conda-forge picrust2=2.3.0_b
   in the Termial,
   
   
   
   after previous process, and then I got this error message:
   
   
   
   the final message just like this:
   
   
   
   However, it can't work with picrust2 yet!
2. from source:
   I download the package of picrust2-2.3.0-b and unzip it. And then
   cd picrust2-2.3.0-b/
   conda env create -f picrust2-env.yaml
   system inform me
   CondaValueError: prefix already exists: /home/qiime2/miniconda/envs/picrust2
   So I run
   conda activate picrust2
   pip install --editable
   
   
   
   However, when I run the pytest, I got these error messages:
   
   

Anyone could give me some suggestions, please! Thanks!

Best wishes

Long

@LXE_Soil_ecol, if you are flexible on which QIIME 2 version you use, installing q2-picrust2, should be easier. This plugin appears only to be supported for use with QIIME 2 2019.2 at this time.

If you need to run picrust2 with the latest version of QIIME 2, @gmdouglas can probably give you a better sense of what barriers stand in your way.

Best of luck!
