ruby - Prepending `bundle exec` to your command may solve this rails -


i having issue while deploying site aws.

gem::loaderror: have activated rake 10.4.2, gemfile requires rake 10.5.0. prepending `bundle exec` command may solve this.   /var/app/ondeck/config/boot.rb:3:in `<top (required)>'   /var/app/ondeck/config/application.rb:1:in `<top (required)>'   /var/app/ondeck/rakefile:4:in `<top (required)>'   loaderror: cannot load such file -- bundler/setup   /var/app/ondeck/config/boot.rb:3:in `<top (required)>'   /var/app/ondeck/config/application.rb:1:in `<top (required)>'   /var/app/ondeck/rakefile:4:in `<top (required)>'   (see full trace running task --trace)    (elasticbeanstalk::externalinvocationerror)

while when gem list rake gives me 

*** local gems ***  airbrake (4.3.1) rake (10.5.0, 10.4.2)

i want have 1 version when bundle exec gem uninstall rake -v 10.4.2 gives me 

error:  while executing gem ... (gem::installerror)     gem "rake" cannot uninstalled because default gem

how resolve issue? appreciated.

you need prefix command bundle exec. example, if rake command is

rake deploy

you have instead use

bundle exec rake deploy

bundler fetch proper gem versions listed in gemfile, , execute command.

java - Callback from new thread to class from which thread was initiated -

i have class calling new thread. public class mainclass{ private void cleardata() { // on separate thread new thread(new runnable() { @override public void run() { //do //after notify mainclass thing has been done , pass value. } } } private void callbackfunc(int a){ // based on value of } } i have function in mainclass. how call function new thread, receive callback. thanks. you should able call method in mainclass name if calling directly inside mainclass (as opposed inner class). if method name want call happens conflict 1 inner class has inherited object can prefix call mainclass.this , e.g. mainclass.this.tostring() calls tostring on mainclass , whereas tostring() calls on inner class instance.
