ImportError: libmapnik.so.3.0: undefined symbol: hb_ft_font_set_load_flags

[robeson1010]

I install a python-mapnik with conda.

But when I import mapnik

the error is: ImportError: libmapnik.so.3.0: undefined symbol: hb_ft_font_set_load_flags

what's that mean?

That probably means you have older version of Harfbuzz than 1.0.5, but your Mapnik was compiled against Harfbuzz of version at least 1.0.5, see this or this.
