swig升级
1、官网下载swig-3.0.12.tar.gz；

2、解压到指定目录；

3、进入解压后的目录，依次运行指令：

bash ./configure --prefix=/usr/local/swig-3.0.12 --without-pcre【即不需要安装pcre依赖】

make && make install

4、蓝后，配置环境变量：
sudo gesit /etc/profile
添加
export SWIG_PATH=/usr/local/swig-3.0.12/bin
export PATH=$SWI{G}_{P}ATH:$PATH
执行
source /etc/profile
5、保存，使环境变量生效；

6、运行swig -version查看版本信息：

SWIG Version 3.0.12

Compiled with g++ [x86_64-pc-linux-gnu]

Configured options: -pcre
