Ruby on Rails與獨角獸不可讀文件

Question

我正在嘗試在Rails環境中構建ruby，但是當我檢查獨角獸狀態時，它給了我以下錯誤，我不知道該怎么辦。 我檢查了config.rb的路徑，它在那里。

/usr/local/rvm/gems/ruby-2.2.2/gems/unicorn-5.1.0/lib/unicorn/configurator.rb:644:in `parse_rackup_file': rackup file (status) not readable (ArgumentError)

Answer 1

確保通過命令運行unicorn ：

bundle exec unicorn -D -E <environment> -c config/unicorn.rb

如果不起作用，請共享您的文件config/unicorn.rb

Answer 2

路徑中存在的文件並不意味着特定用戶可以讀取。 檢查您在其下運行獨角獸的用戶是否有權訪問文件和目錄。 通常，代碼所有者和獨角獸用戶是相同的，因此請使用chown -R that_username:that_username /path/to/app/source 。
