+### 安装pwntools
+先更新 homebrew !!官方的巨慢无比
+
+```
+echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
+source ~/.bash_profile
+```
+安装
+
+执行brew install pwntools等待一会就安装完成，会自动解决依赖关系。安装完后会在/usr/local/Cellar/(可能不一样)目录下生成pwntools文件夹，其中python的包在:
+
+
+/usr/local/Cellar/pwntools/3.6.1/libexec/lib/python2.7/site-packages
+
+/usr/local/Cellar/pwntools/3.6.1/libexec/lib/python2.7/site-packages
+
+然后需要把路径添加到python的sys.path中，这里使用的方法是在默认包目录下创建文件mypkpath.pth然后把目录写进去:
+
+
+$ cd /Library/Python/2.7/site-packages
+$ sudo vim mypkpath.pth
+$ cat mypkpath.pth
+/usr/local/Cellar/pwntools/3.6.1/libexec/lib/python2.7/site-packages
+
+$ cd /Library/Python/2.7/site-packages
+$ sudo vim mypkpath.pth
+$ cat mypkpath.pth
+/usr/local/Cellar/pwntools/3.6.1/libexec/lib/python2.7/site-packages
+
+测试
+
+不报错就可以知道安装成功:
