我在虚拟机（Centos 7）中安装pymssql时遇到了问题

我安装了python 2.7.6版本

用于安装pymssql的命令，

pip intall pymssql

如果你有，请提供一些解决方案，否则如果你能用其他方式在centos7中安装pymssql会有所帮助

Answer 1

您需要安装freetds-devel（yum install freetds-devel），最有可能在EPEL中使用。

Answer 2

文件sqlfront.h由freetds-devel提供。确保已安装

yum install freetds-devel

现在......验证文件是否存在。对于CentOS Linux版本7.1.1503，这是在这里：

ls -l /usr/include/sqlfront.h

找到后，设置C_INCLUDE_PATH，以便pip / gcc可以找到它：

export C_INCLUDE_PATH=/usr/include

现在重新运行pip ...
