将`bundle exec`添加到你的命令可以解决这个问题

Question

我在部署网站时遇到问题AWS.

Gem::LoadError: You have already activated rake 10.4.2, but your Gemfile requires rake 10.5.0. Prepending `bundle exec` to your 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 by running task with --trace)
   (ElasticBeanstalk::ExternalInvocationError)

而当我这样做时,gem list rake它给了我

*** LOCAL GEMS ***

airbrake (4.3.1)
rake (10.5.0, 10.4.2)

我想只有一个版本,当我做bundle exec gem uninstall rake -v 10.4.2它给了我

ERROR:  While executing gem ... (Gem::InstallError)
    gem "rake" cannot be uninstalled because it is a default gem

如何解决这个问题？任何帮助将不胜感激.

Answer 1

首先运行bundle update rake.

我希望这适合你.

Answer 2

您需要为命令添加前缀bundle exec.例如,如果您的rake命令是

rake deploy

你改为使用

bundle exec rake deploy

Bundler将获取您所列出的正确的gem版本Gemfile,并执行该命令.
