client.c:439:3: error: use of undeclared identifier 'my_bool',第1张

解决方式：

把mysql的gem版本换成0.5.2

再bundle

bundle完之後再改回原本的版本就不影响团队开发。

原则就是可以顺利跑完bundle就好，暂时更改版号骗过bundle

Gemfile

gem "mysql2", "~>0.5.2"

发生问题：

$ sudo gem install mysql2 -v 0.3.21

安装OpenVAS

OpenVAS工具的安装比较简单，而且在OpenVAS官网提供了在各种操作系统中的安装方法。其下载地址为http://www.openvas.org/install-packages.html。但是，如果用户在安装时，可能会出现很多依赖包需要手动解决。如果不能够很好的解决依赖关系包，将无法成功安装OpenVAS工具。所以，为了方便用户使用，Kali Linux系统中已经默认安装了该工具，用户可以直接使用。

如果用户发现自己系统中安装的OpenVAS不是最新版本的话，可以通过以下方法安装最新版的OpenVAS工具。具体方法如下所示：

（1）更新软件包列表。执行命令如下所示：

root@Kali :~# apt-get update

执行以上命令后，将会获取最近的软件包列表。

（2）获取到最新的软件包，。执行命令如下所示：

root@Kali :~# apt-get dist-upgrade

执行以上命令后，将会对有更新的包进行下载并安装。

（3）重新安装OpenVAS工具。执行命令如下所示：

root@Kali :~# apt-get install openvas

执行以上命令后，如果没有报错，则说明已成功安装OpenVAS工具。如果当前系统中已经安装了最新版的OpenVAS软件，将会显示以下类似信息：
