這是由於OS X El Capitan發行時已經安裝了六個1.4.1，當它試圖卸載它時（由於awscli依賴於botocore，botocore依賴於python-dateutil，python-dateutil依賴於六> = 1.5）由於系統完整性保護甚至不容許root修改這些目錄。

理想狀況下，點應該跳過卸載這些項目，由於他們沒有安裝到他們安裝到一個特殊的蘋果目錄的網站包。可是，即便點擊跳過卸載這些項目，並安裝六個站點包，咱們會遇到另外一個錯誤，蘋果把他們預先安裝的東西早於sys.path站點包。

解決辦法：

➜  /test sudo pip install --ignore-installed six
