我知道这些问题已经存在,但是没有一个解决方案似乎对尝试产生了任何影响.先感谢您.

我正在尝试重新启动一些需要使用旧版本 openssl 的遗留项目。
我在这里找到了关于这个问题的很好的输入，它在我的一台机器上工作，但在另一台机器上没有，这给了我以下错误：
$ brew switch openssl 1.0.2t
Error: Unknown command: switch
该错误似乎并不常见，在 google/stackoverflow 搜索中没有显示任何有用的信息。
到目前为止我尝试过的：
brew doctorbrew update && brew upgrade我能做些什么来解决这个问题？

我很难通过 pip 安装软件包，这似乎引发了 SSL 错误。
我以前试图为应用程序制作一个新的 Rails 后端。当我尝试 cd 进入应用程序时，终端指出：rvm install "ruby-2.6.5"
当我尝试安装它时，出现错误：
运行“__rvm_make -j8”时出错，
所以，我正在尝试切换到另一个以前运行的应用程序，该应用程序以 Rails 作为后端。
我安装了两个 ruby 版本：2.3.7 和 2.6.1 - 2.6.1 是当前版本。
我正在尝试运行 rails 服务器，当我这样做时 - 终端中出现以下错误：

brew reinstall openssl

我是学习 Python（以及一般编码）的新手，我一直在尝试按照
http://bhowell4.com/manic-install-tutorial-for-mac/
在我的 Mac 上安装 manim。一切都很顺利，直到我尝试使用 pip3 安装 virtualenv。正如指示所述，我输入了
pip3 install virtualenv
进入终端（使用pycharm）。然后它回来了：
pip3 install virtualenv
我试过查看来自不同资源的修复程序，但似乎都不起作用。我试过卸载并重新安装 python3、更新 brew、升级 brew 等。我不确定如何实施其他一些潜在的解决方案。非常感谢初学者可以理解的任何帮助！
