重击"declare -A"在macOS上不起作用 [英] Bash "declare -A" does not work on macOS

问题描述

我的猜测是Bash尚未在macOS上更新.谷歌更新Bash macOS时，我一直在获取错误修复补丁.无论如何，我需要在macOS Bash中使用关联数组，命令如下:

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] [名称[=值] ...]

-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+的功能.

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具有bash 4+的正式更新.

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

酿造/等.可能会.
