群晖安装可道云后，无法更新插件，怎么解决？
更新插件显示错误，我把群晖这个目录的权限全部加起一样不行。
错误如下；
Fatal error: Uncaught Error: Call to undefined function curl_init() in /volume2/web/网站/app/function/web.function.php:312 Stack trace: #0 /volume2/web/网站/app/controller/pluginApp.class.php(203): url_request('http://api.kodc...', 'POST', Array) #1 /volume2/web/网站/app/controller/pluginApp.class.php(144): pluginApp->pluginInfo('zipView') #2 /volume2/web/网站/app/core/Application.class.php(64): pluginApp->install() #3 /volume2/web/网站/app/core/Application.class.php(104): Application->appRun('pluginApp', 'install') #4 /volume2/web/网站/index.php(6): Application->run() #5 {main} thrown in /volume2/web/网站/app/function/web.function.php on line 312
