Hi @coralgal! Sorry to hear things aren't going well. This error means that your shell (the "command line," as it is often referred to) is having a hard time parsing the command it was given. Did you remember to activate your QIIME 2 environment? This step needs to happen any time you open a new shell session, that way your computer know how to find all of QIIME 2's pieces and parts. Let me know if that does or doesn't work for you, we will get you moving in the right direction!! Thanks!
