Mac OS X El Capitan (10.11) sudo pip install 報錯 「OSError: [Errno 1] Operation not permitted」

因爲 OS X El Capitan 採用了 System Integrity Protection 保護技術，致使 sudo pip install 安裝python包時會產生報錯：

1   File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/os.py", line 150, in makedirs
2     makedirs(head, mode)
3   File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/os.py", line 157, in makedirs
4     mkdir(name, mode)
5 OSError: [Errno 1] Operation not permitted: '/System/Library/Frameworks/Python.framework/Versions/2.7/selenium'

SIP 相關命令 csrutil：

 1 xx:~ $ csrutil
 2 usage: csrutil <command>

20         remove <address>
21             Remove an IPv4 address from the list of allowed NetBoot sources.

查看當前SIP狀態：

1 xx:~ $ csrutil status
2 System Integrity Protection status: enabled.

受到SIP保護的路徑：

• /System
• /usr
• /bin
• /sbin
• OS X 預裝的應用

 

若是須要全局安裝python包，則須要先關閉SIP，具體方法以下：

一、重啓系統，重啓過程當中按住option而後選擇恢復分區

二、進入恢復系統後點擊菜單「實用工具」，打開終端，輸入csrutil disable

三、正常重啓

四、sudo pip install xx包

五、安裝完畢後建議進入恢復分區經過終端打開SIP: csrutil enable

 

另外建議：關閉SIP後安裝virtualenv，而後打開SIP，後續經過virtualenv進行環境管理。
