【问题描述】：

硬盘驱动器出现故障后，我刚从商店买了我的 Mac Pro。我正在尝试再次安装我的环境。

我从自制网站上的当前链接安装自制软件：

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

但我无法安装任何软件包。 Brew 找不到任何东西。

 ~ brew install rbenv
Error: No available formula with the name "rbenv"
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
==> Searching taps on GitHub...
Error: No formulae found in taps.

怎么了？

==> Caveats
ruby-build installs a non-Homebrew OpenSSL for each Ruby version installed and these are never upgraded.

To link Rubies to Homebrew's OpenSSL 1.1 (which is upgraded) add the following
to your /Users/rchen/.bash_profile:
  export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl@1.1)"

Note: this may interfere with building old versions of Ruby (e.g <2.4) that use
OpenSSL <1.1.

版本测试

$ rbenv --version
rbenv 1.1.2

【讨论】：

是的，我试过了（抱歉，由于某种原因无法将其格式化为代码）~ brew search rbenv 没有找到“rbenv”的公式或木桶。已关闭的拉取请求：...（太长）
顺便说一句，我设法通过使用 rbenv 存储库而不是 brew 来安装 rbenv 和 ruby，但 brew 仍然无法正常工作。

【解决方案2】：

我遇到了同样的问题，我可以通过运行医生命令并按照需要在那里更新的步骤来解决它。

我的 homebrew-core 不在 master 分支。

brew doctor 
git -C $(brew --repo homebrew/core) checkout master

就是这样。之后，我就可以运行 rbenv install 命令了。
