如何在MacOS Sierra上安装pymssql

Question

Command “/usr/bin/python -u -c “import setuptools, tokenize;file=’/private/tmp/pip-build-J1I0ox/pymssql/setup.py’;f=getattr(tokenize, ‘open’, open)(file);code=f.read().replace(‘\r\n’, ‘\n’);f.close();exec(compile(code, file, ‘exec’))” install –record /tmp/pip-qmtdBW-record/install-record.txt –single-version-externally-managed –compile” failed with error code 1 in /private/tmp/pip-build-J1I0ox/pymssql/

我遇到了与此处显示的错误相同的错误。我尝试按brew install freetds跟随该页面上的指示sudo -H pip install pymssql。

生成此错误代码：

    _mssql.c:18814:15: error: use of undeclared identifier 'DBVERSION_80'
    __pyx_r = DBVERSION_80;
              ^
4 warnings and 1 error generated.
error: command 'cc' failed with exit status 1

----------------------------------------
Command "/usr/bin/python -u -c "import setuptools, tokenize;__file__='/private/tmp/pip-build-J1I0ox/pymssql/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-qmtdBW-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /private/tmp/pip-build-J1I0ox/pymssql/

搜索此错误将我带到了此页面。我也跟着解决方案张贴有通过尝试都brew unlink freetds; brew install homebrew/versions/freetds091和brew uninstall freetds; brew install homebrew/versions/freetds091尝试时产生不同的错误sudo -H pip install pymssql：

_mssql.c:266:10: fatal error: 'sqlfront.h' file not found
#include "sqlfront.h"
         ^
1 error generated.
error: command 'cc' failed with exit status 1

因此，我放弃了尝试安装pyodbc，但是仍然出现类似错误： src/pyodbc.h:56:10: fatal error: 'sql.h' file not found #include sql.h

任何帮助都会很棒。
