Python2.7 - 在 CentOS 6.3 上 pip install pymssql 失败

Question

我正在尝试在 CentOS 机器上为 Python 安装 pymssql，但它一直在我身上失败。

我已经安装了以下内容:

freetds-devel

python-devel

这似乎是我在搜索中不断遇到的修复方法，但是我已经安装了这两个，但我仍然收到以下错误:

所以我在日志中看到这个错误:

_mssql.c:314:22: error: sqlfront.h: No such file or directory In file included from _mssql.c:316:

根据搜索，我需要安装 freetds-devel 和/或 python-devel，但我已经安装了。

我也注意到这一行:

setup.py: Not using bundled FreeTDS

我是基于 Linux 的操作系统的新手，所以我不确定这是否意味着它根本不使用 FreeTDS，或者它是否仅使用我下载的版本而不是捆绑版本或其他什么？这是否表明我下载的 freetds-devel 没有被正确使用？如果是这样，我怎样才能使 setup.py 使用我下载的 freetds-devel？

如果 freetds-devel 不是问题，那么我还缺少其他安装 pymssql 的东西吗？

编辑:更多信息

当我运行以下查找命令时:

sudo find / -name "sqlfront.h"

它提示的文件在这里找到:

/usr/include/freetds/sqlfront.h

那么是我的 FreeTDS 安装出错了还是出了什么问题？

Answer 1

作为所有响应的结果。

在centos 6.3、6.5上安装pymssql需要:

yum install freetds freetds-devel python-devel

将文件从/usr/include/移动到/usr/local/include 并运行

pip install pymssql

或者

pip download pymssql
tar xzf pymsql*tar.gz
cd pymssql*

编辑 setup.py 并将 usr_local 从 '/usr/local' 更改为 'usr' 并运行:

python setup.py install
