是在alpine容器中安装pymssql，一直报错
报错信息如下：

解决方式：
注意：之前试过直接下载freetds包的形式安装，是不行的，需用容器命令安装
参考连接：https://blog.csdn.net/qq_41185868/article/details/80724240
后面查了下，是因为
export PYMSSQL_BUILD_WITH_BUNDLED_FREETDS=1，设置这个环境变量成功的
先进入容器 sudo docker exec -it bc bash export PYMSSQL_BUILD_WITH_BUNDLED_FREETDS=1 然后运行以下命令，安装freetds apk add freetds-dev pip3 --no-cache-dir install pymssql
终于安装成功！！！
