Gem files will remain installed in /usr/local/lib/ruby/gems/2.4.0/gems/json-1.8.3 for inspection.
Results logged to /usr/local/lib/ruby/gems/2.4.0/extensions/x86_64-darwin-16/2.4.0/json-1.8.3/gem_make.out

我一直在搜索,我找不到任何有关这些错误的信息.

我怎么解决这个问题？

Answer 1

似乎JSON 1.8.3与ruby 2.4不兼容..我认为他们现在正在解决这个问题.与此同时,我通过降级为ruby 2.3解决了类似的问题
