python - 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/

我遇到与显示相同的错误 here .我按照该页面上的说明尝试 brew install freetds 然后是 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 this page .我按照那里发布的解决方案尝试了 brew unlink freetds; brew install homebrew/versions/freetds091 和 brew uninstall freetds； brew install homebrew/versions/freetds091 在尝试 sudo -H pip install pymssql 时会产生不同的错误:

_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

于是我放弃并尝试安装 pyodbc，但我仍然遇到类似的错误: src/pyodbc.h:56:10: fatal error: 'sql.h' file not found
#include sql.h

任何帮助都会很棒。
