How to update QIIME2-2018.11 to QIIME2-2019.1

I was trying to update my qiime2 from 2018.11 to 2019.1. I followed this wedside:
first, I checked if I used the latest version of conda, using the following code:

conda update conda
conda install wget
Then, I downloaded and installed qiime2-2019.11 using the following code:
wget conda env create -n qiime2-2019.1 --file qiime2-2019.1-py36-osx-conda.yml
rm qiime2-2019.1-py36-osx-conda.yml
then, I was trying to activate qiime2 by “source activate qiime2-2019.1”, I got an error of “ModuleNotFoundError: No module named ‘qiime2’”.
Anyone knows what should I do now?


Hi @Lin_Li,

Could you run the command, conda list env, to list your conda environments and then conda list -n qiime2-2019.1?

Hi thank you so much for your reply! I solved this issue by removing all the package of qiime2-2018.11 and re-installed qiime2-2019.1 ( >conda env remove -n qiime2-2018.11 and >conda clean -y --all).

Thank you again!!!
