I have "installed" the 7zip Ruby version 2.2.4 as well as the corresponding DevKit. The PATH variable has been set.
When I start the debugging mode in Rubymine 8.0.3 the necessary gems have been installed. But than the following error occurs:
Error running speed: Cannot start debugger. Gem 'ruby-debug-ide' isn't installed or its executable script 'rdebug-ide' doesn't exist.
When I open the command line (cmd.exe) and type c:\rdebug-ide then the command line answers correctly
Using ruby-debug-base 0.2.2.beta6 ...
When I call in the command line gem list then the gem is listed as ruby-debug-ide (0.6.0).
Do somebody has an idea?
Personally I deleted Rubymine from Applications and installed again the last version, now it works for me.
