Problems with SPARQL Tutorial - A First SPARQL Query - sparql

Question

I'm a starter to the sparql, following the sparql tutorial from https://jena.apache.org/tutorials/sparql_query1.html
I used the sparql query function like this:
caihanzhi#ererererermaodeMacBook-Air bin % sparql --data=/Users/caihanzhi/Desktop/vc-db-1.rdf --query=/Users/caihanzhi/Desktop/q1.rq
and the vc-db-1.rdf is
<rdf:RDF
xmlns:rdf='http://www.w3.org/1999/02/22-rdf-syntax-ns#'
xmlns:vCard='http://www.w3.org/2001/vcard-rdf/3.0#'
>
<rdf:Description rdf:about="http://somewhere/JohnSmith">
<vCard:FN>John Smith</vCard:FN>
<vCard:N rdf:parseType="Resource">
<vCard:Family>Smith</vCard:Family>
<vCard:Given>John</vCard:Given>
</vCard:N>
</rdf:Description>
<rdf:Description rdf:about="http://somewhere/RebeccaSmith">
<vCard:FN>Becky Smith</vCard:FN>
<vCard:N rdf:parseType="Resource">
<vCard:Family>Smith</vCard:Family>
<vCard:Given>Rebecca</vCard:Given>
</vCard:N>
</rdf:Description>
<rdf:Description rdf:about="http://somewhere/SarahJones">
<vCard:FN>Sarah Jones</vCard:FN>
<vCard:N rdf:parseType="Resource">
<vCard:Family>Jones</vCard:Family>
<vCard:Given>Sarah</vCard:Given>
</vCard:N>
</rdf:Description>
<rdf:Description rdf:about="http://somewhere/MattJones">
<vCard:FN>Matt Jones</vCard:FN>
<vCard:N
vCard:Family="Jones"
vCard:Given="Matthew"/>
</rdf:Description>
</rdf:RDF>
And the q1.rq is
SELECT ?x
WHERE { ?x <http://www.w3.org/2001/vcard-rdf/3.0#FN> "John Smith" }
But it failed to query. Bash told me that:
Encountered " "{" "{ "" at line 1, column 1.
Was expecting one of:
"\ufeff" ...
"base" ...
"prefix" ...
"select" ...
"describe" ...
"construct" ...
"ask" ...
if anyone knows how to solve it please do not hesitate to provide help!
