我正在尝试运行msfdb，但似乎无法运行，因为我得到了一个LoadError和两个ThreadErrors。这是完整的堆栈：

旁注：据我所知，抛出的2个ThreadErrors是因为我内存不足吗？不过，我总共有16GB，这应该足够了。
在此之前，由于一些奇怪的原因，我无法安装某些依赖项，但我安装了Oracle Instant Client，它允许我安装ruby-oci8，然后让我继续安装其余的依赖项。为此，我重新运行了bundle install，并修复了大部分问题(我不得不用gem install <gem>手动安装某些gem，但重新运行bundle install以确保最后我拥有一切(。现在我得到了这些奇怪的LoadErrors和ThreadErrors。需要注意的一点是，我以root用户的身份执行msfdb run和msfconsole(这对msfdb run来说是必要的，因为它不允许我以普通用户的身份运行它(，但当我以普通使用者的身份运行msfconsole时，metasploit会按预期加载，不会出现任何错误。有人能帮我修一下吗？
从Ruby 3.1开始，net-smtp是一个绑定的gem。
也许，你只需要添加
gem 'net-smtp'
到您的Gemfile。
