 DEPRECATION: Uninstalling a distutils installed project (numpy) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

1. 點選Mac電腦的蘋果圖示
2. 選擇 重新啟動
3. 按住 command＋R，直到進入還原模式
4. 選擇實用工具，然後點選 終端
5. 輸入 csrutil disable 按下回車
6. 重啟電腦

這樣就將“SIP“關閉了。

然後我們使用 pip 安裝升級numpy、scipy等相關的包。

問題是解決了，但是如果到這裡就認為已經萬事大吉了，其實是大錯特錯了。蘋果官方之所以設定“SIP“主要是考慮到系統的安全性問題。所以，我們最好還是將“SIP“開啟。開啟的方式如下： 
1. 點選Mac電腦的蘋果圖示 
2. 選擇 重新啟動 
3. 按住 command＋R，直到進入還原模式 
4. 選擇實用工具，然後點選 終端 
5. 輸入 csrutil enable

但很快就會發現這些源安裝超級慢，所以我推薦大家使用豆瓣的源
