接前一篇文章：AppArmor零知识学习九、源码构建（6）
上一篇文章在进行apparmor源码构建的第五步——Utilties的构建和安装时，在make check这一步出现了问题。解决了dbus-python包的相关问题，但又出现了一个新的问题：ModuleNotFoundError: No module named 'psutil'。本文探索如何解决这个问题并继续往下推进。
还是先使用最常规方法，使用pip install命令尝试进行下载安装，实际命令及结果如下所示：
$ sudo pip install psutil

[notice] To update, run: pip install --upgrade pip
下载安装了psutil包之后，再次执行之前的完整make check命令。实际命令及结果如下所示：

到这一步，我们暂时不再纠缠于这个问题，直接执行安装的步骤，看看是否能够成功。
（4）安装
运行make install命令进行安装。实际命令及结果如下所示：

似乎make check不通过对于Utilties编译和安装没有影响。
至此，Utilties就构建并安装完成了。
