我正在尝试将numpy（和scipy和matplotlib）安装到virturalenv中。
我不断收到这些错误：
RuntimeError: Broken toolchain: cannot link a simple C program
----------------------------------------
Cleaning up...
Command python setup.py egg_info failed with error code 1我安装了xcode的命令行工具
$ which gcc
/usr/bin/gcc
$ which cc
/usr/bin/cc我在Mac OSX 10.9上使用brew安装的python
编辑
是，尝试使用pip进行安装。
整个追溯是巨大的（> 400线）
这是它的一部分：

虽然它很难看，但似乎有效
sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install --upgrade numpy请注意，如果您为numpy以外的程序包收到此错误（例如lxml），请指定该程序包名称而不是numpy在该程序的结尾处。
我看到有人在安装宝石时遇到了类似的问题
Ruby Gem安装Json在Mavericks和Xcode 5.1上失败 - 未知参数：' - multiply_definedsuppress'
这只是一个临时修复，在某些时候必须修复编译器选项
