如何解决这个问题？

标签： installationhomebrew

解决方案

通过查看输出，似乎确实安装了 emacs：

==> Summary
  /usr/local/Cellar/emacs/27.1: 4,009 files, 104.0MB

您应该可以立即使用它。

如果你喜欢GUI 版本，你可以安装它：

brew install --cask emacs

问题

Error: An exception occurred within a child process:
  RuntimeError: /usr/local/opt/emacs not present or broken
Please reinstall emacs. Sorry :(

这是另一个工具 ，cask无法安装：

  • 它无法在/usr/local/opt/emacs.
  • Homebrew 将其安装在/usr/local/Cellar/emacs/27.1.

修复

您可以通过以下方式修复它：

  1. /usr/local/opt/（推荐）在emacs 目录中创建符号链接
$ brew link --overwrite emacs  # if it complains about relinking, run brew unlink emacs && brew link emacs instead
$ brew install cask
  1. （替代）如果上一点没有帮助，安装时忽略依赖项cask
$ brew install cask --ignore-dependencies

请让我知道它是否有帮助
