For BeautifulSoup4 you have to use

Is there a reason you can't use pip or easy_install? Unless you're set on installing from source, you can run either of the following:

有没有理由你不能使用pip或easy_install?除非您已设置从源安装,否则您可以运行以下任一操作:

$ 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easy_install pip安装它):

$ 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 --version on the command line--is the same version displayed as when you run the following in your program?

我不确定为什么你的源安装不起作用。您使用的python解释器是否有可能安装源代码,而您在程序中使用的解释器是否有所不同?尝试在命令行上运行python --version - 与您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)...
