Python 在mac OS X上安装大浮点

我试图在OSX上安装大浮动，但我遇到了多个问题。 我安装了amp，没有任何问题，但当我尝试安装mpfr时，出现以下错误：

Warning: mpfr-3.1.5 already installed, it's just not linked.

这是什么意思？（我正在使用自制软件）

然后，很明显，如果我尝试安装bigfloat，它将不起作用，我会得到以下错误：

必须安装

python-devel

在OS X中，尝试卸载并重新安装：

brew uninstall python
brew install python

另外，根据问题，

Osx GCC

（它只是clang的一个符号链接）不附带现成的

OpenMP

支持。您可以使用

OpenMP

安装

GCC

brew install gcc --without-multilib
