本文介绍了如何通过Jython导入PIP包?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

参考从Jython插入PIP ，看起来Jython可能包含了PIP:

具体如何从Jython本身调用PIP?既要安装软件包，更重要的是要导入该软件包以供参考?

我没有看到用Jython编写的特定代码示例.

解决方案

将Jython 2.7 安装到~/之后，然后:

thufir@doge:~$
thufir@doge:~$ jython --version
Jython 2.7.0
thufir@doge:~$
thufir@doge:~$ pip --version
pip 1.6.dev1 from /home/thufir/jython/Lib/site-packages (python 2.7)
thufir@doge:~$
thufir@doge:~$ pip freeze

for p in players.rushing().sort('rushing_yds').limit(5):
    msg = '%s %d carries for %d yards and %d TDs'
    print msg % (p, p.rushing_att, p.rushing_yds, p.rushing_tds)
(jve) thufir@doge:~/nfl$

尽管并非严格要求使用虚拟环境.

In reference to hooking into PIP from Jython, It looks like, possibly, PIP is included with Jython:

How, specifically, from Jython itself, is PIP invoked? Both to install a package and, more importantly, to import that package for reference?

I've seen no specific code examples written in Jython.

解决方案

Once Jython 2.7 is installed to ~/ then:

thufir@doge:~$
thufir@doge:~$ jython --version
Jython 2.7.0
thufir@doge:~$
thufir@doge:~$ pip --version
pip 1.6.dev1 from /home/thufir/jython/Lib/site-packages (python 2.7)
thufir@doge:~$
thufir@doge:~$ pip freeze
thufir@doge:~$
thufir@doge:~$ pip install virtualenv

although it's not strictly necessary to use the virtual env.
