Sage 7.2 中的 Scikit-learn 和 pandas

Question

我正在尝试将 scikit-learn 和 pandas 放入 Sage 7.2（在 El Capitan 上）。我已经在 Sage 6.6 中成功地做到了这一点。但是，当我输入 /Applications/SageMath-7.2.app/Contents/Resources/sage/sage --pip install scikit-learn（pandas 的结果相同）时，我收到以下错误消息。

我一直找不到任何继续进行的方法。我能想到的唯一问题是安装说明参考 macosx-10.9，但 El Capitan 是 10.11。所以也许这就是问题所在？

您的问题是注释 No such file or directory。我建议你安装命令行工具，甚至 Xcode。你是按照以下顺序做的吗？

安装 Sage
在某个时候，升级您的 Mac OS
升级你的贤者
尝试安装pandas等

如果是这样，可能就是问题所在。我刚刚升级了我的 Mac 并且不得不重新安装命令行工具两次才能识别它。幸运的是，现在这不是很难 - 打开终端并尝试使用 gcc 或其他东西，它应该提示你，尽管你的里程可能会有所不同。

那么你的命令应该可以正常工作，它对我有用。
