Error in rake path

I just created a new rails app in the RubyMine IDE and it tried to run rake but gave this error:

rubygems.rb:340:in 'bin_path': can't find executable rake for rake-0.8.7 &开发者_JAVA技巧lt;Gem::Exception>
              from C:\Ruby192\bin\rake:19:in '<main>'

I then got the same error when I tried to run it outside the IDE in a console.

Can't somebody help or offer some advice?

Is the gem installed

gem list --local | grep rake

If not then

gem install rake
