目前,由于 gcc-4.0 错误,我无法安装任何 Python 包。我将复制两个我遇到的错误示例(一个使用pip,另一个使用手动 setup.py 构建/安装方法):

以下是堆栈上的一些问题/答案,它们解决了相同或相似的问题(但没有为我的问题提供完整的解决方案)。也许这些以前的答案将有助于解决这个问题:
在具有不同 gcc 版本的 Mac OS 10.6 上重新安装 python
如何在 Mac OS X 10.8 / Xcode 4.4 上使用/安装 gcc
这些是我已经做过的事情,建议堆栈用户解决类似问题:
下载 Xcode
在 Xcode 首选项中安装命令行工具
sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
在这个问题上,我已尽我所能以清晰有序的方式提供尽可能多的事实。但是,如果你们需要更多信息,请询问!我很乐意用更多细节来编辑这个问题。
另外,我知道这似乎是一个非常具体的问题,但是通过四处搜索,看起来许多其他人对此问题感到困惑。
如果您不介意,我将非常感谢一个勺子喂养的解决方案(明确说明我必须在终端中做什么来解决这个问题)。我在终端上还不是很舒服,对笼统的答案有点困惑。
谢谢大家的时间,我很感激!
