安装 FreeTDS
FreeTDS is required. On some platforms, we provide a pre-compiled FreeTDS to make installing easier, but you may want to install FreeTDS before doing pip install pymssql if you run into problems or need features or bug fixes in a newer version of FreeTDS. You can build FreeTDS from source if you want the latest. If you’re okay with the latest version that your package manager provides, then you can use your package manager of choice to install FreeTDS. E.g.:
Ubuntu/Debian:
sudo apt-get install freetds-dev
安装了一下,好啦
