Kali更新系统以后，出现msf无法正常启动，提示：
[*] Bundler failed to load and returned this error: ‘cannot load such file -- bundler/setup‘ [*] You may need to uninstall or upgrade bundler
原因：更新系统后Kali默认安装的bundler为最新版本2.1.4。msfconsole依赖的版本为1.17.3。
解决方法：安装旧版本bundler1.17.3
root@kali:~# gem install bundler:1.17.3
Bundler failed to load and returned this error
