OpsWorks Rails App Server設置

Question

我正在嘗試使用默認的Rails App Server安裝程序啟動OpsWorks實例，並且遇到以下錯誤：

================================================================================
Error executing action `run` on resource 'ruby_block[ensure only our unicorn version is installed by deinstalling any other version]'
================================================================================


Errno::ENOENT
-------------
No such file or directory - /usr/local/bin/gem


Cookbook Trace:
---------------
/var/lib/aws/opsworks/cache.stage2/cookbooks/dependencies/libraries/current_gem_version.rb:6:in ``'
/var/lib/aws/opsworks/cache.stage2/cookbooks/dependencies/libraries/current_gem_version.rb:6:in `ensure_only_gem_version'
/var/lib/aws/opsworks/cache.stage2/cookbooks/unicorn/recipes/default.rb:3:in `block (2 levels) in from_file'

下圖是我完成的唯一配置。 我沒有添加任何其他食譜。 （有一些自定義安全組，但是我認為這不會導致上述錯誤。我嘗試使用的實例是Ubuntu 14.04 OS的m3.large。

Answer 1

登錄服務器並輸入

which gem

要么

whereis gem

查看是否返回任何內容。
