This template uses the Wikidata properties:
Lua error in Module:Uses_Wikidata at line 13: attempt to index field 'wikibase' (a nil value).
When adding an infobox using data from Wikidata, please check for consistency with the article and its references, and to address the inconsistencies observed, which can be done by amending the article or the Wikidata entry, or by supplying a better value to the infobox as a local parameter if this is what emerges from the sources.
This version of {{Infobox person}} retrieves various parameter values from Wikidata if enabled ("opt-in"), but only in the absence of a locally supplied value. The template calls Module:Wikidata and Module:WikidataIB.
It allows editors at the article level to blacklist various fields so that they do not display. This makes a positive statement that those fields are unsuitable for inclusion in that article's infobox.

Just use:
{{infobox person/Wikidata | fetchwikidata=ALL}}
and you should get a Wikidata-filled infobox! (Providing the article is linked to a Wikidata entry containing relevant information!). This will by default only fetch information that is sourced on Wikidata. This is an important safeguard for BLPs. The subject's current age (or age at death) will be calculated automatically provided that the dates are sourced and full (i.e. 12 January 1958 not 1958).
This will prevent the infobox from displaying the fields for occupation or children. |noicon=on will suppress the pencil icons in favour of a single "edit on Wikidata" link at the bottom (see Tolstoy, right).
