M1 Mac使用Camelot报错：Ghostscript arm64架构不兼容

在M1 Mac（arm64架构）上使用Python的camelot库读取PDF文件时，出现Ghostscript架构不兼容报错，提示已安装的Ghostscript为x86_64架构，不符合arm64需求。

已尝试的操作 #

• 执行brew install ghostscript安装Ghostscript
• 确认Ghostscript符合camelot官方文档安装要求
• 测试过使用/不使用虚拟环境，问题均存在

疑问 #

已安装arm64版本Python，此前Stack Overflow上同类问题的回复无法解决当前问题，请问该问题是否可以修复？
