在尝试创建资产时:为生产网站预编译我第一次遇到此错误.
rake assets:precompile undefined method directory? for nil:NilClass
我已经成功更新了网站并完成了一项资产:之前多次预编译.
完整的例子:
# RAILS_ENV=production rake assets:precompile --trace
/usr/local/rvm/gems/ruby-1.9.2-p290@pm/gems/rack-1.3.4/lib/rack/backports/uri/common_192.rb:53: warning: already initialized constant WFKV_
** Invoke assets:precompile (first_time)
** Execute assets:precompile
/usr/local/rvm/gems/ruby-1.9.2-p290@pm/gems/rack-1.3.4/lib/rack/backports/uri/common_192.rb:53: warning: already initialized constant WFKV_
rake aborted!
undefined method `directory?' for nil:NilClass
Tasks: TOP => assets:precompile
(See full trace by running task with --trace)
我期待着有人对这一点有所了解,我一直在绞尽脑汁,谷歌搜索答案数小时.
我正在尝试使用Capistrano部署项目,但我收到了这个错误.
当我直接在服务器上运行命令时,会发生同样的事情.以下是输出/opt/rbenv/shims/bundle exec rake assets:precompile --trace
** Invoke assets:precompile (first_time)
** Invoke assets:environment (first_time)
** Execute assets:environment
** Invoke environment (first_time)
** Execute environment
** Execute assets:precompile
rake aborted!
