    Command "/opt/software/python3/bin/python3.4 -c "import setuptools, tokenize;__file__='/tmp/pip-build-u1xa9z99/pymssql/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-e4st_n_f-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-u1xa9z99/pymssql

解决：

export PYMSSQL_BUILD_WITH_BUNDLED_FREETDS=1

[root@host ~]# export PYMSSQL_BUILD_WITH_BUNDLED_FREETDS=1
[root@host-10-134-236-125 freetds-0.91]# pip install pymssql
