更新：我在这里创建了一个github问题https://github.com/spree/spree/issues/7104他们把我链接到这里https://github.com/rubygems/rubygems/issues/1420
但我仍然不知道如何解决我的问题
gem update --system 2.4.8 --no-ri --no-rdoc – 修复它的详细信息在这里https://github.com/remomueller/documentation/issues/7
这是RubyGems 2.5.1中的一个问题，它在RubyGems 2.6.3中得到修复
只需将RubyGems更新到2.6.3或更高版本。
gem update --system 2.6.3
或者如果您使用RVM （来自alf的评论）
rvm rubygems 2.6.3
从Ruby 2.3.0降级到2.2.0为我修复了它
