最近换了电脑，所以又需要配置一下电脑的环境，但是在遇到ruby环境的升级时又遇到了新的问题，所以在此记录一下。
在我之前的文章：https://www.xinwei.ltd/article/87中，已经描述了如何在mac中安装rvm来管理ruby版本的流程和步骤。
但是一些异常情况仍然可能会出现，因为电脑系统版本等问题，这里出现的就是其中一种。

截图：
正如报错中所示，说没有更新Homebrew，但是当我执行brew update命令时，提示当前的Homebrew已经是最新版本。
所以肯定是由其他问题导致的，那我们打开报错中的log文件，看能不能找到具体问题：

所以依然提到是Homebrew的问题，但我没有发现Homebrew哪里有问题，brew update也已经执行过了，brew命令也能正常执行，所以要考虑其他问题。
恰巧我以前在配置电脑环境中也遇到过openssl版本的问题，所以我怀疑是不是跟openssl版本有关系，这样想的原因是印象中有要把openssl升级到1版本的需要，然后在网上查到确实也有人提出要升级openssl的解决办法，索性尝试一下。
从截图中可以看出，我电脑上的openssl已经是最新的，有点奇怪。
那我在执行命令时，尝试直接指定openssl的位置，试一下，结果成功了。
最终解决方案（ruby最新版本是3.4.6）：
terminal
rvm install ruby-3.4.6 --with-openssl-dir=$(brew --prefix openssl@1.1)
查看是否生效：
terminal
➜ ~ rvm docs generate-ri
Generating ri documentation.....................................
➜ ~ rvm list
=* ruby-3.4.6 [ x86_64 ]
# => - current
# =* - current && default
# * - default
➜ ~ 这样就可以了。
