Centos 6-sudo不'；安装mysqlclient for Python 3.4时无法识别pip3.4

我不熟悉

Centos 6

和

Linux

我需要安装

Python3.4

，但是

Centos 6

默认安装了

Python2.6.6

。
我已将

Python3.4

安装到

/usr/local/lib/Python3.4

但是，我在安装

mysqlclient

时遇到问题

我尝试了

pip3.4安装mysqlclient

。
这是错误消息

编辑：找出问题所在。Sudo不认识pip3.4。此链接有助于：

您是否先安装了mysqlclient（rpm）？听起来好像找不到它需要的标题

sudo-yum安装mysql-devel-mysql-lib

请参见

Hi，您能否指出/home/username/.pip/pip.log日志文件包含的内容？在“错误：命令“gcc”失败，退出状态为1”之前是否有任何内容？@scytale-有一个很长的列表，但这是它的一部分，直到“…”为止，其余的是一堆消息，抱怨它找不到成员或初始化错误。您是否先安装了mysqlclient（rpm）？听起来它好像找不到它需要的头。我试过了，但它仍然抱怨在我运行脚本时找不到MySQLdb模块。每当我尝试使用pip3.4安装任何软件包时，它都不起作用。是否有用于python 3的mysqldb模块？对于Python3，我使用mysql连接器（因为它没有任何依赖项-不需要安装mysql）。sudo pip安装-允许外部mysql连接器python mysql连接器python然后导入mysql.connector然后其余调用几乎相同请参见是的，它是mysqlclient。同样的脚本在Windows环境中也可以正常工作。我不得不将脚本迁移到linux服务器进行测试。如果我使用pip安装mysqlclient-它安装到python 2.6.6，如果我使用“sudo pip3.4安装mysqlclient”-它会抱怨它无法识别pip3.4。尝试过sudo pip3安装吗？还是和sudopip3.4一样？python3.4是否安装了pip？是的，应该安装。我可以在/usr/local/bin中看到pip3.4。我甚至添加了-export PATH=“/usr/local/bin:$PATH”。我刚试过SudoPip3，但它一点也认不出来。

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