Question

在cron和命令提示符下，我运行bundle exec rake cache:clear并记录我的缓存目录中的所有文件，并将其删除，但事实并非如此。文件仍然存在，我可以使用remove命令删除它们。我已经确认它有文件权限。还有什么呢？

这是运行cron作业的用户。以下是命令的输出：

RAILS_ENV=production bundle exec rake cache:clear --silent

***** initializing cache clear *****

***** deleting /social *****



***** deleting main cache *****

/var/www/site/tmp/cache/81d0fc6f96d4c6c957a26c932e3f2b471a56bc82.cache
/var/www/site/tmp/cache/1db90a7553f8440babe0f23932a674096184feb2.cache
/var/www/site/tmp/cache/b6d4cb2a18a5599605fec8880fc08d8604cbba07.cache

我可以以部署用户身份登录并重现此行为。执行rake任务会列出文件，但不会删除它们。使用rm命令我可以成功删除它们。

决议是使用

rake tmp:clear

rake cache：clear说它删除了文件，但它不是
