Error in profiling a single metagenome from raw reads

I’m new to metaphlan, and trying to run the tutorial. But there was a problem with the first step. How can I solve this problem?

Hi @sakura
Thanks for getting in touch. I think the problem you are experimenting is due to the missing installation of bowtie2. Could you run the following command bowtie2 -h ? In case the latest one returns an error, you can try to manual install bowtie2 using conda conda install -c bioconda bowtie2
