Pandas Scikit学习Sage 7.2中的熊猫

我正在尝试将scikit learn和pandas放入Sage 7.2（在El Capitan上）。我在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

（与

pandas

的结果相同）时，我会收到以下错误消息

我一直找不到任何方法继续。我能想到的唯一问题是安装说明参考的是

macosx-10.9

，但El Capitan是10.11。所以可能就是这个问题吧？

你的问题是注意

没有这样的文件或目录

。我建议你安装命令行工具，甚至是Xcode。你做了吗按以下顺序排列

安装Sage

在某个时候，升级你的Mac操作系统

升级您的Sage

尝试安装熊猫等

如果是这样的话，可能这就是问题所在。我刚刚升级了我的Mac电脑，在它识别它之前，我不得不重新安装了两次命令行工具。幸运的是，现在这并不难——打开一个终端，尝试使用

gcc

或其他东西，它会提示你，尽管你的里程可能会有所不同

---

那么您的命令应该可以正常工作，对我来说也可以。

就是这样。升级到El Capitan后，我没有重新安装Xcode命令行工具。完成了，现在scikit和pandas安装正确。谢谢。
