问题描述
我无法在没有警告的情况下在OS X Mountain Lion上安装gmpy(1或2).我尝试了pip，我尝试了编译，我安装了gcc 4.2.1，并尝试使用i386 arch(尽管我的Mac是64位)来编译gmp，但是它们都无法正常工作！
I cannot install gmpy (1 or 2) on OS X Mountain Lion without warnings. I tried pip, I tried compiling, I installed gcc 4.2.1 and tried to compile gmp with i386 arch (though my Mac is 64bit), none of them are working!
问题是我可以在没有警告的情况下使用Python 3+来设置gmpy，但在Python 2.7中则不能.
The thing is I can setup gmpy with Python 3+ without warnings but not with Python 2.7.
使用时得到的详细信息:
The verbose I get when I use:
python setup.py install是:

推荐答案
IIRC，引起此错误的原因是python以32位应用程序的身份运行，但试图将gmpy编译为64位扩展名.查看此问题报告:
IIRC, this error is caused because python is running as a 32-bit application but is trying to compile gmpy as 64-bit extension. See this issue report:
