声明-A返回无效选项使用Apple M1上的Bash版本5

我已经阅读了有关Stackoverflow的类似文章，但是没有解决我的特定问题，我真的很感谢任何帮助，因为我真的在这本书上失去了理智。

我有一个使用Shebang ＃！/usr/bin/env bash的脚本，我已经使用Echo在脚本内检查了bash的版本，它的确是bash版本5我通过Homebrew下载的 - 我读到我不需要使用路径/opt/homebrew/bin/bash 它是我的bash所在的位置[苹果M1 CPU] Shebang粘贴在第1点。
我的VSC终端正在使用ZSH。
由于某种原因，即使声明-a应由4后bash版本支持，但我返回以下错误： 声明：-a：无效选项声明：用法：声明[-affirtx] [-p] [-p] [name [= value] ...]
我的脚本如下：

#!/usr/bin/env bash

echo "BASH_VERSION=$BASH_VERSION"

# save current branches in packages as `composer install` may change them to master
SCRIPTPATH="$( cd "$( /usr/bin/dirname "$0" )" && pwd )"

DIR=`pwd`

declare -A BRANCHES

DIR=`pwd`

for d in */; do

    cd "$DIR/$d"
    BRANCH=`git rev-parse --abbrev-ref HEAD`

    if [ "${BRANCH}" != "master" ]; then
        BRANCHES[$d]="${BRANCH}"
    fi

done

返回的bash版本：

BASH_VERSION=5.1.16(1)-release

有建议吗？请让我知道您需要哪些其他细节。另外，也许是宣布关联数组的替代语法，也许我在初始化之前无法声明它们？

我也对此有一个问题。该脚本位于Docker目录内 - 如果Docker打算将虚拟Linux用于安装和实例 - 那么为什么我需要对我的Shell脚本进行某些MACOS支持的更改？

I have read similar articles on stackoverflow but none addressing my specific issue, I would really appreciate any help as I am really losing my mind on this one.

I have a script that is using the shebang #!/usr/bin/env bash, I have checked the version of bash inside of the script by using echo and it is indeed bash version 5 that I downloaded via HomeBrew - I read that I do not need to use the path /opt/homebrew/bin/bash which is where my bash is situated [apple M1 cpu] because of the shebang pasted in point 1.
My vsc terminal is using zsh.
For some reason even though declare -A should be supported by bash versions after 4, I am returned the following error:
declare: -A: invalid option declare: usage: declare [-afFirtx] [-p] [name[=value] ...]
My script is as follows:

#!/usr/bin/env bash

echo "BASH_VERSION=$BASH_VERSION"

# save current branches in packages as `composer install` may change them to master
SCRIPTPATH="$( cd "$( /usr/bin/dirname "$0" )" && pwd )"

DIR=`pwd`

declare -A BRANCHES

DIR=`pwd`

for d in */; do

    cd "$DIR/$d"
    BRANCH=`git rev-parse --abbrev-ref HEAD`

    if [ "${BRANCH}" != "master" ]; then
        BRANCHES[$d]="${BRANCH}"
    fi

done

Returned bash version:

BASH_VERSION=5.1.16(1)-release

Any advice? Please let me know what other details you require. Also, perhaps an alternative syntax to declaring associative arrays, perhaps I cannot declare them before initializing?

I have a subsequent question regarding this as well. This script sits inside of a docker directory - if docker is meant to use the virtual Linux for installations and instances - why then would I need to make certain macOS supported changes to my shell scripts?
