将Drupal版本从7.34更新为最新版本，但每次都获取错误消息“无法获取可用的更新数据”。因此无法更新。从数据库中清除缓存表的各种事项以及所有增加的执行时间和所有内容，但是没有用。请帮忙
答案 0 :(得分：0)
在过去的几个小时里，我一直在努力解决这个问题。我使用的更新方法是通过User尝试将所有内容更新为最新版本。
我认为核心和/或其他模块正在更新，但在验证管理界面时无法获取X项目的可用更新数据错误消息。
对我来说，运行drush pm-update会显示以下结果：
drush pm-update -v运行vagrant@localhost:/var/www/web$ drush pm-update -v

错误。
稍后修改
5分钟后重新运行simplexml_load_file(): I/O warning : failed to load external entity "" Project.php:72会显示大量 [ok] ，而不是上面的 [错误] 或 [警告] 。验证管理员还显示了一条正面消息：检查了X项目的可用更新数据。
所以最后我认为这是一个更新细节可用性问题。
