实际上我在travis构建中遇到了这个错误。 我的Gemfile是：

group :default do
gem 'highline'
gem 'dir'
gem 'fileutils2'

gem 'streamio-ffmpeg'
gem 'rainbow'
gem 'gli'
end
# Add dependencies to develop your gem here.
# Include everything needed to run rake, tests, features, etc.
group :development do
gem 'rdoc', '~> 4.1.0'

end
group :test do

end

我在Stackoverflow中搜索并找到了一个bundle install或者再次删除锁和捆绑安装的答案。
我也尝试使用bundle install -deployment，但是那个使用了所有依赖项，而我的* .gem大约是60M（通过使用rake release）。
有更好的解决方案吗？
答案 0 :(得分：0)
我找到了解决方案。问题是，我已经覆盖了.travis.yml的安装部分。因此bundle install尚未执行且未找到。
所以修复： 从
install:
- sudo apt-get install ubuntu-restricted-extras ffmpeg
到
before_install:
- sudo apt-get install ubuntu-restricted-extras ffmpeg
