The problem arose when I tried to run installations of different gems... e.g.:

Once I execute, I get the error:

Since OSX el Capitanthere is a new security function that prevents you from modifying system files called Rootless. So you have 2 options:
由于OSX el Capitan有一个新的安全功能可以防止您修改名为 Rootless 的系统文件。所以你有两个选择：
If you install gems on
/usr/local/binthere will be no problem because rootless doesn't affect this path.sudo gem install -n /usr/local/bin GEM_NAME_HERE
如果你安装 gems 就
/usr/local/bin没有问题，因为 rootless 不会影响这个路径。sudo gem install -n /usr/local/bin GEM_NAME_HERE
