我正在尝试按照官方网站上的建议通过 Homebrew 包管理器在 Mac 上安装 PyMOL 的开源版本：https ://pymolwiki.org/index.php/MAC_Install#Open-Source_PyMOL 。

在安装过程中，Homebrew 将 pango 依赖从 1.46.1 升级到 1.46.2，删除旧版本，然后在检查时抛出错误。

这个错误来自哪里的任何想法？以及如何解决？

错误：没有这样的文件或目录 - /usr/local/Cellar/pango/1.46.1

$ ruby -v
ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin19]

$ brew reinstall pango

$ brew install ruby   
(if you already have an old version, then reinstall it by:)
$ brew reinstall ruby

然后你的 ruby​​ 应该更新到 2.7.2，但是，可能存在配置问题。

==> Caveats
By default, binaries installed by gem will be placed into:
  /usr/local/lib/ruby/gems/2.7.0/bin

You may want to add this to your PATH.

ruby is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have ruby first in your PATH run:
  echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> /Users/lydia/.bash_profile

For compilers to find ruby you may need to set:
  export LDFLAGS="-L/usr/local/opt/ruby/lib"
  export CPPFLAGS="-I/usr/local/opt/ruby/include"

For pkg-config to find ruby you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/ruby/lib/pkgconfig"

我也收到了同样的错误：错误：/usr/local/Cellar/libusbmuxd/HEAD-3eb50a0 is not a directory。运行后收到此错误：~ brew update ~ brew outdated

简单运行： ~ brew install pango
（Pango 是 i18n 文本布局和渲染的框架）

在运行升级之前，请确保您的 Apple 命令行工具也已更新。

然后我就可以运行了： ~ brew upgrade

一切正常更新，没有任何错误。我根本不需要更新 ruby​​。
