python:机械化的漂亮汤,不在共享主机上工作

我正在写一个小的网站装饰工 make my local airport site work with standard HTML .

在本地计算机上,我使用python的 mechanize 和 BeautifulSoup 用于抓取和解析站点内容的包,一切似乎都正常工作。我已通过安装这些软件包 apt-get .

在我的共享宿主网站上(位于 DreamHost )我已经下载了 .tar.gz 文件,提取包,重命名目录(例如, BeautifulSoup-3.1.0.tar.gz 到 美人汤 )试图运行命令。

我对BeautifulSoup有一个奇怪的错误;我不知道它是关于DreamHost上的一个旧版本的Python、目录名还是其他原因。

>>> r=br.open(url)
>>> html=r.read()
>>> type(html)
<type 'str'>

我这样做是为了证明输入确实是一个字符串。现在让我们运行在本地计算机中工作的命令:

>>> soup    =   BeautifulSoup.BeautifulSoup(html)

    val))

    return _compile(pattern, 0).sub(repl, string, count)

有什么想法吗?
