我总是运行brew更新忽略bigdecimal-1.3.2,因为它的扩展没有构建.尝试：gem pristine bigdecimal –version 1.3.2警告显示：
> brew update Ignoring bigdecimal-1.3.2 because its extensions are not built. Try: gem pristine bigdecimal --version 1.3.2 Ignoring bigdecimal-1.3.2 because its extensions are not built. Try: gem pristine bigdecimal --version 1.3.2 Already up-to-date.
我正在使用Homebrew v1.7.7(Homebrew / homebrew-core(git revision 77cae; last commit 2018-10-19),Homebrew / homebrew-cask(git revision c95843; last commit 2018-10-19))和rbenv v1 .1.1.
我已经做了宝石质朴的bigdecimal –version 1.3.2,它说：
> gem pristine bigdecimal --version 1.3.2
ERROR: While executing gem ... (Gem::Exception)
Failed to find gems ["bigdecimal"] = 1.3.2
甚至宝石原始 – 所有都没有固定它.
宝石环境向我展示了2条宝石路径.那很好吗？

解决方法
确保你使用正确的宝石.以下为我修好了：
$which ruby /usr/local/bin/ruby $/usr/bin/gem uninstall bigdecimal --all --force
(编辑：修复“删除”到“卸载”)
