无法安装gem错误：执行gem…（Errno :: EACCES）

Question

I'm trying to install gem 'passenger' on my project to use nginx. But when I do

$ gem install passenger

error comes out like,

ERROR:  While executing gem ... (Errno::EACCES)
    Permission denied @ rb_sysopen - /home/ubuntu/.rvm/gems/ruby-2.2.2@rails-devise/gems/passenger-5.0.22/.editorconfig

I found that this error is related to my version of ruby and rails. Actually this project started from ruby version 2.2.2 , and rails version 4.2.5 . But my ubuntu already has ruby version 2.2.1 , and rails version 4.2.4 , this means I installed ruby and rails using rvm at the /home/ubuntu .

So I was trying to match the version of my envirnment and my project by reinstalling ruby and rails, using rvm install ruby-2.2.2 , gem install rails --version=4.2.5 . But I still get same error.

What I want to do is making my envirnment works fine.(installing gem, matching version correctly using rvm or etc.) Any ideas or document that I can read? As you can see, I'm not good at Linux. So if you have any recommendations, please let me know. Thanks.

This issue is not related to version of ruby or rails. Could you tell me as which user are you trying to run this command by whoami ?

The actual problem seem to be that the file /home/ubuntu/.rvm/gems/ruby-2.2.2@rails-devise/gems/passenger-5.0.22/.editorconfig is not accessible by the current user.
