前言
在 MacOS 下使用 sed -i 就会出现类似下面的错误
代码语言：javascript复制sed: 1: "...": command c expects followed by text
sed: 1: "...": command i expects followed by text原因是由于 MacOS 下默认的 sed 和 Linux 下是不一样的，导致 -i 无法正确识别，通常的做法是安装一个 gnu-sed 已替换原本的 sed 命令
安装步骤
代码语言：javascript复制# 查询一下
which sed
# 安装
brew install gnu-sed
# 查看
brew info gnu-sed
==> gnu-sed: stable 4.9 (bottled)
GNU implementation of the famous stream editor
https://www.gnu.org/software/sed/
Conflicts with:
ssed (because both install share/info/sed.info)
Installed

==> Caveats
GNU "sed" has been installed as "gsed".
If you need to use it as "sed", you can add a "gnubin" directory
to your PATH from your bashrc like:
PATH="/opt/homebrew/opt/gnu-sed/libexec/gnubin:$PATH"
配置环境变量
将 PATH="/opt/homebrew/opt/gnu-sed/libexec/gnubin:$PATH" 部分配置到 ~/.zshrc 里面就可以了，别忘记 source 让它生效哦。
验证
代码语言：javascript复制# 记得验证一下
which sed
# 当然你也可以直接使用 `gsed`
