我正在尝试在CentOS机器上安装Python的pymssql,但是它一直在我身上失败。
我已经安装了以下内容:
freetds-devel
蟒-devel的
这似乎是我在搜索中遇到的修复,但是我已经安装了这两个并且我仍然收到以下错误:
pip install pymssql

所以我在日志中看到了这个错误:
_mssql.c:314:22:错误:sqlfront.h:没有这样的文件或目录_mssql.c中包含的文件:316:
来自搜索的内容表明我需要安装freetds-devel和/或python-devel,但我已经安装了。
我也注意到这一行:
setup.py:未使用捆绑的FreeTDS
我是基于Linux操作的新手,所以我不确定这是否意味着它根本不使用FreeTDS,或者它只是使用我下载的那个而不是捆绑版本的东西?这是否表明我下载的freetds-devel可能没有正确使用?如果是这样,我如何使setup.py使用我下载的freetds-devel?
如果freetds-devel不是问题,那么安装pymssql还有其他的东西吗?
编辑:更多信息当我运行以下find命令时:
sudo find / -name“sqlfront.h”
它抱怨的文件在这里找到:
/usr/include/freetds/sqlfront.h
只是我的FreeTDS安装搞砸了或出了什么问题?
答案 0 :(得分:3)
你需要这些标题,这就是它失败的原因。
你可以做一个吗?sudo find / -name“sqlfront.h”
以下是可能的答案:
Error while install pymssql in centos 7
做一个:
yum install freetds-devel
安装后重试。
答案 1 :(得分:3)
您没有提到您正在使用的CentOS版本。既然你说过Python 2.7我会假设CentOS 7.如果你使用的是CentOS 6并使用本地构建的Python,请更新你的问题。
无论如何,在我的CentOS 7系统上:
# rpm -q centos-release
centos-release-7-1.1503.el7.centos.2.8.x86_64
安装EPEL存储库后:
# yum -y install epel-release
然后安装要求:
# yum -y install gcc python-pip python-devel freetds-devel
我能够成功pip install
pymssql
:
# pip install pymssql

Cleaning up...
答案 2 :(得分:3)
所有回复的结果。
要在centos 6.3上安装pymssql,6.5需要:
yum install freetds freetds-devel python-devel
将文件从/ usr / include /移至/ usr / local / include并运行
pip install pymssql
或
pip download pymssql
tar xzf pymsql*tar.gz
cd pymssql*
修改setup.py并从' / usr / local'更改usr_local到了' usr'并运行:
python setup.py install
答案 3 :(得分:0)
看起来这些文件与setup.py配置所在的位置不同。
为了解决这个问题,我将文件从/ usr / include /复制到了usr / local / include
然后运行
pip install pymssql
成功了。
我引用了这个答案 - Installing pymssql in Centos 6.6 64-bit
我想更改为setup.py使用的路径会更好,但我无法找到成功执行此操作的方法。
答案 4 :(得分:0)
将sqlfront.h所在的包含路径添加到:
export C_INCLUDE_PATH=/usr/include/freetds/
然后再次pip安装pymssql。
答案 5 :(得分:-1)
我有同样的错误。您必须安装freetds-devel。
