I installed qiime2 on Mac, activated and checked the installation with qiime--help, everything is fine. however, when I running command, such as_ _ join_paired_ends.py -i $PWD/R1Index.fastq, -r $PWD/R1Index.fastq, -o $PWD/Barcode.fastq
-bash: join_paired_ends.py: command not found
Could you please let me know what’s run? Thanks a lot!
