url = 'https://www.bond-y.com{e.xpath("//a[@rel=\'next\']/@href")}'
或者
url = '''https://www.bond-y.com{e.xpath("//a[@rel='next']/@href")}'''
你单引号把字符串断了

url = "https://www.bond-y.com{e.xpath('//a[@rel=\"next\"]/@href')}"
url = 'https://www.bond-y.com{e.xpath("//a[@rel=\'next\']/@href")}'

e.xpath表达式有问题
next_page_link = e.xpath("//a[@class='next']/@href")# 修正XPath表达式

少一个f"",我看见是这样

你字符串用的是单引号包裹的，里面再出现单引号的话要用转义字符即 \' 来代替

转义后还报错
