如何在spaCy管道中的记号赋予器之前添加组件？

import spacy

from spacy.pipeline import EntityRuler

nlp = spacy.load('en_core_web_sm')

component = EntityRuler(nlp)
nlp.add_pipe(component, before='ner')

patterns = [{'label': 'ORG', 'pattern': 'Apple'}, {'label': 'GPE', 'pattern': [{'LOWER': 'san'}, {'LOWER': 'francisco'}]}]
component.add_patterns(patterns)

text = "Apple is headquartered in San Francisco."
doc = nlp(text)

for ent in doc.ents:
    print(ent.text, ent.label_)

Apple ORG
San Francisco GPE
