Is there a reason you can't use pipor easy_install? Unless you're set on installing from source, you can run either of the following:
是否有不能使用的原因pip或easy_install？除非您设置为从源代码安装，否则您可以运行以下任一命令：
$ easy_install BeautifulSoup
Or, if you have pip(which I recommend, you can install it with easy_install pip):
或者，如果你有pip（我推荐，你可以用 安装它easy_install pip）：
$ pip install BeautifulSoup
I'm not certain why your source install isn't working though. Is it possible the python interpreter you're using to install the source and the interpreter you're using in your program are different? Try running python --versionon the command line--is the same version displayed as when you run the following in your program?
我不确定为什么您的源安装不起作用。您用于安装源代码的python解释器和您在程序中使用的解释器是否可能不同？尝试python --version在命令行上运行-- 显示的版本与在程序中运行以下内容时显示的版本相同吗？
import sys
print sys.version # => '2.7.2 (default, Feb 4 2012, 02:01:30)...
