找不到类Requests_Hooks。 我已经做了研究并重新安装了wordpress并把相同版本的requests文件夹放了？

I have blog installed on my sub domain. The wordpress installed is also on same server. When i try to access the blog from main website Like this

define('WP_USE_THEMES', false);

require($_SERVER['DOCUMENT_ROOT'] . "/blog/wp-load.php");

It throws an error

PHP Fatal error:  Class 'Requests_Hooks' not found in pathtoblog/blog/wp-includes/class-wp-http-requests-hooks.php on line 17

I have re-installed the wordpress. Updated the wordpress to latest version. Put the Requests folder again. None works

define('WP_USE_THEMES', false);

require($_SERVER['DOCUMENT_ROOT'] . "/blog/wp-load.php");// Error occurs here 

also tried

require($_SERVER['DOCUMENT_ROOT'] . "/blog/wp-blog-header.php"); // Same error
