Python：机械化和BeautifulSoup不在共享主机上工作

Question

我正在写一个小型网站设计师到make my local airport site work with standard HTML。

在我的本地计算机上，我使用Python的mechanize和BeautifulSoup软件包来抓取和分析网站内容，并且一切看起来都很顺利。我已经通过apt-get安装了这些软件包。

在我的共享主机的网站（在DreamHost）我已经下载了.tar.gz文件，提取的包，改名目录（例如，从BeautifulSoup-3.1.0.tar.gz到BeautifulSoup），并试图运行命令。

我与BeautifulSoup有一个奇怪的错误;我不知道它是关于Dreamhost上的Python旧版本，关于目录名称还是其他原因。

[sanjose]$ python 
Python 2.4.4 (#2, Jan 24 2010, 11:50:13) 
[GCC 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)] on linux2 
Type "help", "copyright", "credits" or "license" for more information. 
>>> from BeautifulSoup import BeautifulSoup       
>>> import mechanize             
>>> url='http://www.iaa.gov.il/Rashat/he-IL/Airports/BenGurion/informationForTravelers/OnlineFlights.aspx?flightsType=arr' 
>>> br=mechanize.Browser()                         
>>> br.addheaders = [('User-agent', 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)')]         
>>> r=br.open(url) 
>>> html=r.read() 
>>> type(html) 
<type 'str'> 

我这样做是为了表明输入确实是一个字符串。现在让我们运行在我的本地计算机上运行的命令：

>>> soup = BeautifulSoup.BeautifulSoup(html)

    self.attrs = map(convert, self.attrs)

    val)) 
    File "/usr/lib/python2.4/sre.py", line 142, in sub 
    return _compile(pattern, 0).sub(repl, string, count)

任何想法？

您正在使用适用于Python 3.x的BeautifulSoup版本3.1.0。使用3.0版本的BeautifulSoup for Python 2.x.
