python - Centos 6 - sudo 在为 Python 3.4 安装 mysqlclient 时无法识别 pip3.4

Question

我是 Centos 6 和 Linux 的新手。
我需要安装 Python 3.4 但是 Centos 6 默认为 Python 2.6.6。
我已经安装Python 3.4到/usr/local/lib/Python3.4。

但是，我在安装 mysqlclient 时遇到问题。

我试过 pip3.4 install mysqlclient。

这是错误信息。

编辑:找出问题所在。 Sudo 不识别 pip3.4。此链接有帮助:Installing Python3.4 and the SciPy stack on CentOS

sudo /usr/local/bin/pip3.4 install mysqlclient

你有没有先安装mysqlclient (rpm)？听起来它找不到它需要的标题

sudo yum install mysql mysql-devel mysql-lib
