QIIME empress command error


I am new to qiime2 and recently participated in a QIIME2 course via FAES.
I have been trying to use the q2-empress command but always return and error message below.

Error: QIIME 2 has no plugin/command named 'empress'.

I am working in qiime2-2021.11 via conda. Help will be very much appreciated.


Hi @mfrimpong,

Glad you were able to join the :qiime2: FAES workshop!

This error implies that q2-empress has not been installed within your QIIME 2 environment (i.e. q2-empress is not part of the base QIIME 2install. Did you follow this instructions as outlined here?

Often users forget to run the qiime dev refresh-cache portion of the install instructions.

-Let us know how it goes. :slight_smile:


Hi @SoilRotifer

I am also trying to use empress which I learned from the FAES workshop. I followed the steps you referred (QIIME 2 Library) but having this error in installing Empress.

Any feedback will be highly helpful.

@SoilRotifer - I think I figure out the problem.

Pip needed to be installed first.

Thank you for much for putting this together.
