我在安装 upx 时遇到问题。以下是我采取的步骤。我的 macOS 是 11.2.1
% ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null
==> Checking for `sudo` access (which may request your password).
==> This script will install:
/usr/local/bin/brew
/usr/local/share/doc/homebrew
/usr/local/share/man/man1/brew.1
/usr/local/share/zsh/site-functions/_brew
/usr/local/etc/bash_completion.d/brew
/usr/local/Homebrew
==> /usr/bin/sudo /usr/sbin/chown -R vuduc:admin /usr/local/Homebrew
==> Downloading and installing Homebrew...
HEAD is now at 3ff5795ae Merge pull request #10652 from danielnachun/revert-gcc-linkage-fix
==> Installation successful!
==> Homebrew has enabled anonymous aggregate formulae and cask analytics.
Read the analytics documentation (and how to opt-out) here:
https://docs.brew.sh/Analytics
No analytics data has been sent yet (or will be during this `install` run).
==> Homebrew is run entirely by unpaid volunteers. Please consider donating:
https://github.com/Homebrew/brew#donations
==> Next steps:
- Run `brew help` to get started
- Further documentation:
https://docs.brew.sh
% brew install upx
Updating Homebrew...
fatal: Could not resolve HEAD to a revision
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
Error: No available formula or cask with the name "upx".
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.
我该如何解决这个问题？我需要安装 upx，因为当我尝试运行某些应用程序时，它们会显示“您无权打开应用程序……”。
