我想使用 Bootstrap V 4.0 及更高版本的组件，实际结果是 Bootstraps 3.3.7 的组件。 当我尝试 Gem 更新时，这是我获得的:
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
server did not return a valid file (http://gems.rubyforge.org/specs.4.8.gz)
我安装了 Bootstrap，但我开始使用 Bootstrap 3.3.7 并更新到 4.0。从那以后我遇到了问题。 这是我在代码文件中的 Gemfile:

最佳答案
@valentine 只需删除 gem.lock 然后执行 bundle install 我认为应该可以修复该错误我没有足够的评论点所以将其写在答案中
关于ruby-on-rails - 当我尝试更新 Gem 时遇到问题，服务器没有返回有效文件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/54763045/
