以上输出在我的终端上。我使用的是Mac OS 10.7.x。我有Python 2.7.1，并遵循本教程获得了Beautiful Soup和lxml，它们都成功安装了，并与位于这里的单独测试文件一起工作。在导致此错误的Python脚本中，我包含了这一行: 导入comparePages 在pageCrawler文件中，我包含了以下两行代码: 从bs4导入BeautifulSoup 从urllib2导入urlopen

任何帮助找出问题是什么以及如何解决都将不胜感激。

我在Ubuntu 11上使用easy_install安装lxml有困难。

当我输入$ easy_install lxml时，我得到:

似乎没有安装libxslt或libxml2。我试着按照http://www.techsww.com/tutorials/libraries/libxslt/installation/installing_libxslt_on_ubuntu_linux.php和http://www.techsww.com/tutorials/libraries/libxml/installation/installing_libxml_on_ubuntu_linux.php上的说明操作，但没有成功。

如果我试着wget ftp://xmlsoft.org/libxml2/libxml2-sources-2.6.27.tar.gz我得到

<successful connection info>
==> SYST ... done.    ==> PWD ... done.
==> TYPE I ... done.  ==> CWD (1) /libxml2 ... done.

==> PASV ... done.    ==> RETR libxml2-sources-2.6.27.tar.gz ... 
No such file `libxml2-sources-2.6.27.tar.gz'.

如果我先尝试另一个，我会得到。/configure——prefix=/usr/local/libxslt——with-libxml-prefix=/usr/local/libxml2，最终会失败:

checking for libxml libraries >= 2.6.27... configure: error: Could not find libxml2 anywhere, check ftp://xmlsoft.org/.

我尝试了libxml2的2.6.27和2.6.29两个版本，没有什么不同。

不遗余力，我已经成功地完成了sudo apt-get安装libxml2-dev，但这没有改变什么。
