我知道我可以使用Java安装Jython,并且可以在使用Python的地方使用Jython。Jython外壳运行良好。
在Jython中,我该如何安装类似的库lxml,Scrappy而BeautifulSoup该库通常是通过pip或安装的easy_install
lxml,Scrappy
BeautifulSoup
pip
easy_install
某些Python模块(如)lxml在C中具有必需的组件。它们在Jython中不起作用。
lxml
大多数Python软件包都可以正常运行,你可以使用与CPython相同的工具来安装它们。在Jython Book的附录A中对此进行了描述:
要获得setuptools,请从http://peak.telecommunity.com/dist/ez_setup.py下载ez_setup.py 。然后,转到你保留下载文件的目录并执行:
$ jython ez_setup.py
[easy_install脚本将被安装]安装到Jython安装的bin目录中(/home/lsoto/jython2.5.0/bin在上面的示例中)。如果你经常使用Jython,则最好将此目录添加到PATH环境变量之前,这样就不必每次都要使用easy_install或其他安装到此目录的脚本时都键入整个路径。
/home/lsoto/jython2.5.0/bin
在Jython中安装setuptools之后,我自己进行了测试,正确安装了pip:
