Sinatra错误:无法激活sinatra-contrib-1.4.2

Question

尝试运行Sinatra应用程序时，我一直收到以下错误：

/Users/matthewsmith/.rbenv/versions/2.1.2/lib/ruby/2.1.0/rubygems/specification.rb:2064:in `raise_if_conflicts': 
Unable to activate sinatra-contrib-1.4.2, because tilt-2.0.1 conflicts with tilt (~> 1.3) (Gem::LoadError)
from /Users/matthewsmith/.rbenv/versions/2.1.2/lib/ruby/2.1.0/rubygems/specification.rb:1262:in `activate'
from /Users/matthewsmith/.rbenv/versions/2.1.2/lib/ruby/2.1.0/rubygems.rb:196:in `rescue in try_activate'
from /Users/matthewsmith/.rbenv/versions/2.1.2/lib/ruby/2.1.0/rubygems.rb:193:in `try_activate'
from /Users/matthewsmith/.rbenv/versions/2.1.2/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:132:in `rescue in require'
from /Users/matthewsmith/.rbenv/versions/2.1.2/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:144:in `require'
from app.rb:3:in `<main>'

这是我的Gemfile：

gem 'sinatra', '~> 1.4.5'
gem 'activerecord'
gem 'pg'

我试着把

gem 'tilt', '~> 1.3' 

在Gemfile中也是如此，但这并不起作用。

有什么想法吗？

Answer 1

我也有同样的问题。我删除了Tilt 2.0.1，我的应用程序可以正常工作。

删除gem：

$ gem uninstall tilt -v 2.0.1
Successfully uninstalled tilt-2.0.1

$ bundle install

Bundle complete! 9 Gemfile dependencies, 17 gems now installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.

已重新启动应用程序(通过Pow)：

~/app-dir$ touch tmp/restart.txt

Answer 2

在我的Gemfile中指定：

gem 'sinatra-contrib', github: 'sinatra/sinatra-contrib'

和运行

bundle update

帮我修好了。
