Scikit學習和熊貓鼠尾草7.2

Question

我試圖把scikit學習和熊貓放入聖人7.2（在埃爾卡皮坦）。我在Sage 6.6中成功完成了這個任務。但是，當我輸入/Applications/SageMath-7.2.app/Contents/Resources/sage/sage --pip install scikit-learn（pandas的結果相同）時，我收到以下錯誤消息。

我一直無法找到任何處理方法。我能想到的唯一問題是安裝說明參考macosx-10.9，但El Capitan是10.11。所以也許這就是問題所在？

Answer 1

你的問題是筆記No such file or directory。我建議你安裝命令行工具，甚至是Xcode。你是否按照以下順序做事情？

1. 安裝賢者
2. 在某些時候，升級您的Mac OS
3. 升級你的賢者
4. 嘗試安裝熊貓等

如果是這樣，可能這就是問題所在。我剛剛升級了我的Mac，並且必須重新安裝命令行工具兩次才能識別它。幸運的是，現在這不是很難 - 打開終端並嘗試使用gcc或其他東西，它應該提示你，雖然你的里程可能會有所不同。

然後你的命令應該可以正常工作，它適用於我。
