当 op 编辑他的帖子并以他的代码格式修复空格时，我正在更新我的答案。
当程序请求链接时，写下（或粘贴）您的链接并在按回车之前添加一个空格。
输入末尾的多余空格将阻止 IDE 在浏览器窗口中打开链接，而不是使用返回键结束输入，因此它将按预期继续执行输入函数后的下一个代码。
这样做，您的代码实际上可以正常工作，正如我在第一个答案中所展示的那样。
我之前的回答：
我注意到你在这里有不正确的空格'a-color-base'
替换这一行：
linkElems = soup.select('div.a-row a.a-size-base.a-link-normal.review-title.a- color-base.a-text-bold')
与
linkElems = soup.select('div.a-row a.a-size-base.a-link-normal.review-title.a-color-base.a-text-bold')
额外：
目前您的代码也仅适用于 amazon.com ，要使您的代码适用于其他亚马逊网站，如 amazon.in amazon.co.uk，您需要修改此行：
webbrowser.open('https://amazon.com' + linkElems[i].get('href'))
类似于：
from urllib.parse import urlparse
url_components = urlparse(url)
webbrowser.open('https://' + url_components.netloc + linkElems[i].get('href'))
现在它可以与 amazon.in 等其他亚马逊网站正常工作，而不仅仅是 amazon.com，试试吧。

如果您的调试函数抛出错误：
我不确定您的实际代码中的这个空间是否存在，或者它在此处以错误的帖子格式显示，但无论如何您应该从格式 arg '% (levelname)s' 中删除空格，以便调试按预期工作：
替换这个：
logging.basicConfig(level=logging.DEBUG, format=' %(asctime)s - % (levelname)s - %(message)s')
与
logging.basicConfig(level=logging.DEBUG, format=' %(asctime)s - %(levelname)s - %(message)s')
希望这会对你有所帮助。
