brew 找不到任何包

Question

硬盘驱动器出现故障后，我刚从商店买到 Mac Pro。我正在尝试重新安装我的环境。

我从自制软件网站上的当前 link 安装了自制软件：

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

但是我无法安装任何包。 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.

Answer 2

我遇到了同样的问题，我能够通过运行ning 医生命令并按照需要在那里更新的步骤解决它。

我的 homebrew-core 不在 master 分支。

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

就是这样。在那之后，我能够运行 rbenv install 命令。
