Hi @yoshikisuzu,
It looks like you installed picrust2, not q2-picrust2 (the QIIME 2 plugin for picrust2). You installed these in separate environments and they don’t know how to talk to each other!

You should follow the installation instructions here to install q2-picrust2 in your qiime2-2020.2 environment:


Thank you your polite advise.

I executed the program following your opinion.

but that did not go well.

Please see the actual screen.
The conflict error seems to occur.

I was wondering if it would be possible for you to advice me?
Thank you very much.

Dear @yoshikisuzu,
That error message is not very revealing, as it looks like you aborted the installation process. Please run again and wait until it produces a complete error message so that we can see what packages are in conflict.

Alternatively, install q2-picrust2 in your qiime2-2019.10 environment. As the picrust2 version is also 2019.10, it is possible that it has not been updated to be made compatible with qiime2-2020.2 and this is where the package conflict is arising.

Good luck!


Hi @yoshikisuzu
Have you dealed with this problem? The same error occured when I install this plugin to qiime-2020.8. Maybe the version of q2-picrust2 dont match qiime2.
