make: *** [generator.o] Error 1

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

我搜索了很多，但找不到任何关于这些错误的信息。

我该如何解决？

Answer 1

似乎JSON 1.8.3 is not compatible with ruby 2.4. 。我认为他们现在正在解决这个问题。与此同时，我通过降级到 ruby​​ 2.3 解决了类似的问题

Answer 2

我也遇到了同样的问题。我从他们的网站安装了 Cocoapods 应用程序，这使我能够构建我的应用程序所需的 cocoapods（集成 firebase）。

https://github.com/CocoaPods/CocoaPods/issues/6299#issuecomment-269282062

安装命令行工具似乎对我有用，但希望损坏的依赖项 (json1.8.3) 将得到修复，以便正确构建。

希望这对您有所帮助，直到找到更永久的解决方案。

Answer 3

与 gem 'github-pages' 相同的问题，尝试安装 json..

通过降级到 ruby​​ 2.3 解决了我的问题：

`brew install rbenv ruby​​-build

将 rbenv 添加到 bash 以便在每次打开终端时加载 echo '如果哪个 rbenv > /dev/null;然后 eval "$(rbenv init -)"; fi' >> ~/.bash_profile 来源 ~/.bash_profile

安装 Ruby rbenv 安装 2.3.3 rbenv 全球 2.3.3 红宝石-v`
