ruby - bundle 安装错误 'error occurred while installing json (1.7.3)'

Question

我是初学者，在尝试安装 Bundle 时无法理解如何修复错误。我正在学习 Schneems 类(class)(目前正在做 routes_controller_exercise)。

这是我的错误:

我不知道该怎么办。我是初学者所以...请对我好一点!我一直在网上尝试很多解决方案，但到目前为止没有任何效果!我使用的是 El Capitan 10.11.1。

我已经使用此链接设置了 Ruby:http://guides.railsgirls.com/install/#virtual-machine .

现在做这个练习:https://github.com/schneems/routes_controller_exercise

更新:

所以我做到了:

bundle update json 

它一直有效，直到:

解决方案

好的，我已经卸载 rails 并使用 Stanford 网站重新安装它。

现在一切正常!我不知道问题出在哪里，但现在我安装 Bundle 没有任何问题。

部分问题是由于 rb_str_new 中的更改所致.

这是他们 GitHub 页面上的一个相关问题:https://github.com/flori/json/issues/229

据我了解，贡献者决定不修复此问题，因为它在 json 1.8.3 中正常工作。建议您升级到该版本。 json gem 有一个非常稳定的 API，因此向后兼容性通常不是问题。

如果您正在使用 bundler ，您应该转到您的 Gemfile并使用 gem 'json', '>=1.8.3' 将 json 版本更改为 1.8.3 或更高版本.
