您是否以root用户身份登录?如果是这样，则您不需要sudo.

Are you logging in as root? If so, then you have no need for sudo.

如果没有，那么/root/.bashrc的内容将无关紧要，因为sudo命令从运行它的环境中获取其路径.换句话说，它会复制您的用户级路径.而是在用户的.bashrc中编辑路径.

If not, then the contents of /root/.bashrc won't matter, since the sudo command gets its path from the environment in which it's run. In other words, it copies your user-level path. Instead, edit the path in your user's .bashrc.
