Bash“声明-A"不适用于 macOS [英] Bash "declare -A" does not work on macOS

问题描述

我的猜测是 Bash 没有在 macOS 上更新.当谷歌搜索更新 Bash macOS 时，我不断收到错误修复补丁.无论如何，我需要在 macOS Bash 中使用关联数组，其中命令:

My guess is that Bash is not updated on macOS. When googling update Bash macOS, I keep getting the bug fix patch. Anyway, I need to use associative arrays in macOS Bash where the command:

declare -A

产生错误:

-bash:声明:-A:无效选项
声明:用法:声明 [-afFirtx] [-p] [name[=value] ...]

-bash: declare: -A: invalid option
declare: usage: declare [-afFirtx] [-p] [name[=value] ...]

我有优胜美地.

推荐答案

declare -A(关联数组)是 bash 4+ 的特性.

declare -A (associative arrays) are a bash 4+ feature.

OS X bash 可能是 3.X.

The OS X bash is likely 3.X.

我不知道 OS X 有针对 bash 4+ 的官方更新.

I don't know that OS X has an official update for bash 4+.
