我的 MacBook Air 配备了 macOS Mojave 版本 10.14.6。即使我检查了brew版本，我也无法安装wget。
brew --version
输出是：
Homebrew 3.3.13
Homebrew/homebrew-core (no Git repository)
Homebrew/homebrew-cask (git revision fb6ec06d8b; last commit 2022-01-31)
当我尝试安装 wget 时：
brew install wget
这是结果：
Warning: No available formula with the name "ca-certificates".

Error: No similarly named formulae found.
