Unable to download metaphlan2

Dear all
My metaphlan2 version is metaphlan2 2.9. I want to convert it to metaphlan2 2.7 as humann2 support metaphlan2 2.9. Please suggest

If you use Conda you can simply specify the version to install
conda install metaphlan2=2.7.8

Would recommend creating an specific environment with conda and then installing metaphlan2 and humann2 in that environment. You shouldn’t try to convert 2.9 to 2.7. Remove and do clean installs.

best

Thanks @bigdoyle for suggestions.
