问题描述

我在使用美丽汤的Google应用引擎中制作了一个应用。我正在使用它的最新版本, http://www.crummy。 COM /软件/ BeautifulSoup / BS4 /下载/ 4.0 / 。一切工作正常,直到我上传到GAE。然后发生的事情是我得到了这个错误:

smart_quotes_re = b([\x80- \ x9f])
^
SyntaxError:无效语法

当我看看dammit.py中的第254行,我发现这个:

  if(self.smart_quotes_to不是None 
并且提议($)中的.lower()在self.ENCODINGS_WITH_SMART_QUOTES):
smart_quotes_re = b([\x80-\x9f])
smart_quotes_compiled = re.compile(smart_quotes_re)
markup = smart_quotes_compiled。 sub(self._sub_ms_char,markup)

我真的不明白什么是错的。尝试过其他版本的BS,但他们不工作,因为我使用的只是se的soup.select(CSS SELECTOR) ems工作在最新版本。不过,正如我刚才所说,它在我的电脑上运行良好,但不在云端。

解决方案

BeautifulSoup 4需要Python 2.7或更新版本,但Appengine默认使用Python 2.5。您可以:


I have made an application in Google app engine that is using Beautiful Soup. I'm using the latest version of it, http://www.crummy.com/software/BeautifulSoup/bs4/download/4.0/. Everything worked fine until i uploaded it to GAE. The thing that happend then was that I got this error:

Traceback (most recent call last):
  File "/base/python_runtime/python_lib/versions/1/google/appengine/ext/webapp/_webapp25.py", line 701, in __call__
    handler.get(*groups)
  File "/base/data/home/apps/s~app/1.358226218191077920/main.py", line 285, in get
    self.response.out.write(self.makeQuery("9147094591"))
  File "/base/data/home/apps/s~app/1.358226218191077920/main.py", line 191, in makeQuery
    from bs4 import BeautifulSoup
  File "/base/data/home/apps/s~app/1.358226218191077920/bs4/__init__.py", line 29, in <module>
    from .builder import builder_registry
  File "/base/data/home/apps/s~app/1.358226218191077920/bs4/builder/__init__.py", line 279, in <module>
    from . import _htmlparser
  File "/base/data/home/apps/s~app/1.358226218191077920/bs4/builder/_htmlparser.py", line 23, in <module>
    from bs4.element import (
  File "/base/data/home/apps/s~app/1.358226218191077920/bs4/element.py", line 6, in <module>
    from bs4.dammit import EntitySubstitution
  File "/base/data/home/apps/s~app/1.358226218191077920/bs4/dammit.py", line 254
    smart_quotes_re = b"([\x80-\x9f])"
                                     ^
SyntaxError: invalid syntax

When I look at line 254 in dammit.py I find this:

if (self.smart_quotes_to is not None
    and proposed.lower() in self.ENCODINGS_WITH_SMART_QUOTES):
    smart_quotes_re = b"([\x80-\x9f])"
    smart_quotes_compiled = re.compile(smart_quotes_re)
    markup = smart_quotes_compiled.sub(self._sub_ms_char, markup)

I can't really see what is wrong. I've tried other versions of BS but they don't work because I'm using the soup.select("CSS SELECTOR") which only seems to work in the latest version.

But, as I said earlier, it worked fine on my computer but not in the cloud.

解决方案

BeautifulSoup 4 needs Python 2.7 or newer, but Appengine has Python 2.5 by default. You can either:
