如何在Jython中安装各种Python库？

Ran*_*ngh 46 python java jython pip easy-install

我知道我可以用Java安装Jython,并且我可以在使用Python的地方使用Jython.Jython shell工作正常.

在Jython中,我如何安装类似的库lxml,Scrappy并且BeautifulSoup我通常通过pip或安装easy_install

有些Python模块lxml需要C语言中的组件.这些组件在Jython中不起作用.

大多数Python包都可以正常工作,您可以使用与CPython中使用的相同的工具来安装它们.这在Jython Book的附录A中描述:

要获取setuptools,请从http://peak.telecommunity.com/dist/ez_setup.py下载ez_setup.py .然后,转到您离开下载文件的目录并执行:
$ jython ez_setup.py

[easy_install脚本将]安装到Jython安装的bin目录中(/home/lsoto/jython2.5.0/bin在上面的示例中).如果您经常使用Jython,最好将此目录添加到PATH环境变量中,这样您就不必在每次要使用easy_install或安装到此目录的其他脚本时键入整个路径.

在Jython中安装setuptools后,我自己进行了测试,正确安装了pip:
