Question

项目包在json安装时因错误而停止。但我不是要求在Gemfile中使用json。 RVM中的当前Ruby是1.9.2-p290，严格。

不知道解决这个问题。可能有帮助吗？

 An error occurred while installing json (1.7.7), and Bundler cannot continue.
 Make sure that `gem install json -v '1.7.7'` succeeds before bundling.

任何帮助，任何事情，都将非常感激。：）

即使您没有明确地将json列为依赖项，您正在使用的其他宝石也可能会这样做。因此，Bundler会将其包含在捆绑列表中。

要检查哪个库正在使用json，您可以检查Gemfile.lock文件或使用bundle viz绘制依赖关系树。

即使在Gemfile中没有json，Bundler也会在json安装上停止
