在Mac OS X Mountain Lion上安装gmpy

Question

我无法在没有警告的情况下在OS X Mountain Lion上安装gmpy (1或2)。我试过pip，我试过编译，我安装了gcc 4.2.1，还试过用Mac编译gmp (虽然我的i386是64位的)，但它们都不能工作！

问题是，我可以使用Python 3+设置gmpy而不会出现警告，但不能使用Python2.7。

我在使用以下命令时得到的详细信息：

gmpy2的python setup.py install为：

Answer 1

IIRC，导致此错误的原因是python作为32位应用程序运行，但试图将gmpy编译为64位扩展。请参阅此问题报告：
