在运行“ brew install brewsci / bio / pymol”时发生Brew错误“无此文件或目录-/usr/local/Cellar/pango/1.46.1”

问题描述

我试图按照官方网站https://pymolwiki.org/index.php/MAC_Install#Open-Source_PyMOL上的建议，通过Homebrew软件包管理器在Mac上安装PyMOL的开源版本。

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

您知道此错误来自何处吗？以及如何解决？

解决方法

Error: No such file or directory - /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

然后您的ruby应该更新为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"
