python - 在 mac osx(雪豹)上安装 numpy

Question

我正在尝试在我的 mac 机器上安装 numpy。无论我尝试什么，当我尝试运行我的 python 代码时，我最终都会收到此错误

此外，当我在终端中输入 Python 时，它会将我带到 python 2.6.1 版本。我该如何解决这个问题？

根据错误消息中的路径，您似乎打算为已安装的 Python 2.7 安装 Numpy。您将获得 Python 2.6。这表明您的 PATH 环境变量有问题。调整 .bash_profile 中的 PATH 变量，以便 Python 2.7 的可执行文件出现在 /usr/bin 中的系统版本之前。
