json-parse-buffer错误

[superfpga]

1.环境：Debian11/emacs28.1

2.请教一下各位大佬，配置emacs-application-framework后，启动emacs后，遇到了如下的错误，不知道有没有同仁遇到过，试着上网找答案，但是没有结果，没有办法，特来请教，先谢谢了！！！

3.emacs --debug-init启动的错误信息：

json-parse-buffer Emacs 27 就存在了呀，为啥你没有这个函数？

是呀，很奇怪，我也查了是从27开始就有，估计是我编译安装时候没有--with-json，我再试试

1.卸载emacs28，重新安装emacs27.2，没有报这个错误了 2.再重新安装emacs28，有编译错误，在分析中，json错误应该就是安装有问题 3.eaf还在试用，谢谢猫哥指点

在emacs30中，使用doom方式加载eaf，出现了同样的问题：Debugger entered--Lisp error: (void-function json-parse-buffer) 配置如下：

(use-package! eaf
  :load-path "~/.emacs.d/emacs-application-framework"
...
