项目需要，在python中调用java方法。于是乎在mac下安装jpype，网上有win32下的安装程序(.exe)，没有直接的安装程序，需要编译源码安装。我下载的时是JPype-0.5.4.2，里面有如下文件：
这里的setup.py就是要运行的安装程序。
执行安装程序：python setup.py install。
报错：

从log来看，这里是找不到"jni.h"头文件。
看下setup.py，其中有个设置头文件的函数 ：
在mac下，jni.h头文件的路径是：
/System/Library/Frameworks/JavaVM.framework/Versions/A/Headers/
为了让安装程序能找到jni.h头文件，需要在这里加入jni.h的路径。修改setupInclsion(self)函数：
再次执行安装命令。
还报错：

这个好办，权限问题。
用root权限执行安装：sudo python setup.py install。
哦了！
