Php 运行Composer更新时出现恼人的Sensio分发包警告

运行$composer update时，我不断收到以下警告：

PHP警告：文件_get_contentsapp/bootstrap.cache:无法打开流：第176行的/home/kevin/www/project1/vendor/sensio/distribution bundle/sensio/bundle/DistributionBundle/Composer/ScriptHandler.PHP中没有此类文件或目录 PHP堆栈跟踪： PHP1。{main}/home/kevin/www/project1/vendor/sensio/distribution bundle/sensio/bundle/DistributionBundle/Resources/bin/build_bootstrap.php:0 PHP2。Sensio\Bundle\DistributionBundle\Composer\ScriptHandler:：doBuildBootstrap/home/kevin/www/project1/vendor/Sensio/distribution Bundle/Sensio/Bundle/DistributionBundle/Resources/bin/build\u bootstrap.php:30 PHP3。文件\u get\u contents/home/kevin/www/project1/vendor/sensio/distribution bundle/sensio/bundle/DistributionBundle/Composer/ScriptHandler.php:176

有什么想法吗？

这种情况偶尔发生，我必须手动删除缓存的文件夹 /app/cache/dev | prod{dev|u old或其他什么}

或者只是简单地运行php应用程序/控制台缓存：clear

无论我是否清除缓存，它都会在编写器更新时发生
