ruby-on-rails - rails 在启动时记录错误

Question

我在启动 Rails 应用程序时看到以下错误:

$ script/server --environment=production

我在 log 目录上执行了 chmod -R 0666，现在权限如下所示。 “我”是我作为 sshed 的普通用户。

drw-rw-rw-  2 me me  4096 2010-07-31 18:48 log

只有当我执行 sudo ls -al log 时，我才会得到这个 list :

drw-rw-rw-  2 me me 4096 2010-07-31 18:48 .
drwxr-xr-x 14 me me 4096 2010-07-31 19:32 ..
-rw-rw-rw-  1 me me   51 2010-07-31 18:45 ?development_delayed_jobs.log
-rw-rw-rw-  1 me me  527 2010-07-31 18:59 development.log
-rw-rw-rw-  1 me me   51 2010-07-31 18:48 ?production_delayed_jobs.log
-rw-rw-rw-  1 me me   51 2010-07-31 18:48 production.log

如果我执行 ls -al log，我会收到以下错误(通过 ssh):

chmod 目录 755 或 775，您需要对目录执行访问才能访问它。
