使用 gfortran 支持为 Lion Python 2.6 构建 numpy

【问题标题】：Building numpy for Lion Python 2.6 with gfortran support使用 gfortran 支持为 Lion Python 2.6 构建 numpy
【发布时间】：2012-08-02 18:39:15
【问题描述】：

我正在尝试在 Lion OS 随附的预装 Python 2.6 上安装 numpy 和 scipy。

这是我正在采取的具体步骤：

  • 安装一个干净的副本
    • 狮子，
    • 更新，
    • Xcode（来自应用商店），
    • 自制，
    • gfortran,
    • 点，
    • 和 numpy。
  • 下一步是尝试升级 numpy。
    以下是发生的情况：（我无法发布完整日志，因为我是受限用户。

我非常感谢任何帮助/评论/指导。

【问题讨论】：

  • @abarnert：非常感谢您的帮助。如果我（受限用户）有办法发布完整日志，请告诉我。我收到一条错误消息，说我需要更多声誉才能发送长问题。如有必要，我可以将其上传到网站或其他地方。干杯
  • 您最好将代码发布到 pastebin（或等效项）中，并总结您问题的兴趣点。 SO 格式喜欢一个特定的点，而不是大量的数据转储......请将此作为建设性的批评:) 然后是有足够代表的人。可以编辑您的问题，或者可以制作要求您挑选一些内容并修改您的问题的 cmets...交换条件...-然后，希望您能得到答案，并且它与所有相关点一起存档以帮助其他人稍后出...
  • 你是否从 Xcode 安装了命令行工具？
  • @tabchas：感谢您的评论一百万。我安装了命令行工具，它就像一个魅力！所以为了以后的参考，问题中提到的所有步骤都是正确的。只需添加以下步骤：安装 Xcode 后，转到 Xcode 首选项，下载，在组件选项卡下，安装命令行工具。非常感谢大家！
  • 嘿没问题...我前段时间购买 Macbook 时遇到了同样的问题。

【解决方案1】：

你试过官方的安装说明吗？

【讨论】：

  • 官方安装只适用于从 python.org 下载的 Pythons
