Linux上的mysqlclient pip失敗

Question

我正在研究Python3.4 / Django項目（在CentOS 6.8x64上），並且正在嘗試安裝mysqlclient驅動程序。 盡管進行了數小時的谷歌搜索，但我仍無法弄清楚如何在安裝過程中解決看起來像編譯錯誤的問題。

據我所知，我已經安裝了所有必需的庫軟件包，但到目前為止還沒有運氣。 這是輸出（對不起，很抱歉）：

Answer 1

我猜您需要安裝mysql-devel或mariadb-devel（如果在centos 6上已經可用）才能進行編譯。

yum install mysql-devel

Answer 2

原來這是mysqlclient和最新版本的MariaDB（10.2）之間的兼容性問題。 我調整了軟件包的存儲庫，使其指向較舊的MariaDB版本（10.0或10.1），並安裝了其中一個版本，然后mysqlclient構建並安裝沒有問題。
