Java调用Python时，找不到Python的requests库

[永远的326]

想用Java调用一个Python的爬虫，但是报错说找不到requests, 不知哪位朋友遇到过这样的问题，最后怎样解决的？谢谢！

Java代码：
import org.python.core.Py;
import org.python.core.PySystemState;
import org.python.util.PythonInterpreter;

public class Main {

public static void main(String[] args) {
// TODO Auto-generated method stub
// 定义参数
String url = "http://www.baidu.com";
String[] args2 = { url };
// 设置参数
PythonInterpreter.initialize(null, null, args2);
PythonInterpreter interpreter = new PythonInterpreter();
PySystemState sys = Py.getSystemState();
interpreter.execfile("E:\\Study\\PythonCode\\DaliyTest\\Jython.py");
}
}

Python代码：
#!/bin/env python
import time
import sys
import requests
argCount = len(sys.argv)
time.sleep(5);
for str in sys.argv:
print str

报错：
Exception in thread "main" Traceback (most recent call last):
File "E:\Study\PythonCode\DaliyTest\Jython.py", line 4, in <module>
import requests
ImportError: No module named requests
