Bundler is not working with remote sdk in Linux and rbenv

I  installed bundler according to the event log[ RubyMine Gem Manager: RubyMine has detected that some of the gems required for 'XXX' are not installed. Install], 

but this error was not fix. After this install action, same event log was displayed.

And other conditions were below, 

1) Tools > Bundler > Install Bundler is only displayed, and other commands(Update and Install etc) is not displayed).

2) Gem list of this ruby sdk is not shown in the [Ruby SDK and Gems] section.

3) Gem environment:
