首先说明，msf最好还是安装在linux下，安装在windows下的话问题实在太多了。
1. Metasploit-framework v6.2.19 Setup Wizard ended prematurely
截图如下：
出现这个的原因其实很简单：权限不够。
所以，只需要切换成administrator，或者以管理员权限运行cmd，在cmd中执行安装文件即可。
2. msfdb init失败
报错如下：

出现这种报错就是因为第1个错误，也就是msf的相关文件没有安装完全。
同时，这个错误反应在msfconsole中就是使用db_status等命令时提示：No database driver installed
3.msfdb init出现以下错误：
别看数据库在启动，但是永远也启动不了。目前这个错误原因还不是很清楚，也没找到直接的解决方法。
只想到了一个替代方案：安装一个postgresql，然后让msf连接到这个安装的postgresql上。
但是后续还有很多麻烦的地方。所以，msf的数据库问题我就放弃了，还是乖乖用kali上的msf吧。
