尝试索引时 Nginx 权限出现错误（实际文件运行正常）

Question

我在 Mac 上通过 Homebrew 安装了 nginx。我最近尝试添加虚拟 php 服务器。当我访问正确的文件名时，它工作正常，但在调用 try 块或应提供索引文件时出现权限错误。

#200 :
http://php-sandbox.dev/index.php
#404 :
http://php-sandbox.dev/index
http://php-sandbox.dev/

文件 index.php 存在于根 Web 目录中，并且具有 744 权限，其路径中的所有文件夹也具有 744 权限。

index 指令显然被忽略了。请参阅下面的示例和错误以及我的 nginx 配置。

nginx 的站点配置文件：server { listen 80; listen [::]:80; error_log /var/log/nginx/php-sandbox/error.log debug; rewrite_log on;

    server_name php-sandbox.dev;

    root        /Users/sswright/repos/jswright61/php-sandbox/public;
    index       index.php index.html;

    include drop.conf; #ignores favicons

    location / {
        try_files $uri $uri.php $uri/ =404;
    }

    location ~ \.php$ {
            fastcgi_split_path_info ^(.+\.php)(.*)$;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
            fastcgi_pass 127.0.0.1:9000;
    }
}

try 块正在执行，但尚未尝试索引。

这里正在寻找 index.php，但出现权限错误。当请求 /index.php 时，页面可以正常加载。
