Invalid syntax message when running export2graphlan

I am running GraPhlAn taking as a reference the turorial:

I tried to run the step 1 (to create the GraPhlAn input files), but I got an error message:

File "/home/eyre/anaconda3/bin/", line 23
    def scale_color((h, s, v), factor=1.0):
SyntaxError: invalid syntax

I installed export2graphlan again (conda install export2graphlan) but it has the same error message.

Is it possible that I should need to install it differently?

Thank you.
