Aborted (core dumped)

运行 rake spec 时，我得到了上面的结果。我无法运行我的 Rails 项目。

1) 有人可以解释我如何使用这些信息来查找错误吗？

2) 谁能看到我的个人问题？我正在尝试运行 Gitlab，这是一个相当大的项目，其他人可能会遇到它

3) 如果这确实是一个错误，我该如何解决？更改 rails 版本？更改 ruby 版本？我该怎么做。

我在 Ubuntu 上并通过 RVM 安装。所以我可以通过它改变 ruby 版本。那我的 gem 呢？ ~> x.x.x 选项和 bundle 安装？

Answer 1

其中一个依赖项 json gem 似乎有问题。按照您的编号:

1. 当您看到段错误时，它通常涉及不匹配的 gemset 或针对错误版本的 ruby​​ 编译的 gem native 扩展，因此您应该朝那个方向看。

   事实上，第一行报告 gem 是从一个 ruby​​ 2.0.0p247 gemset 中获取的，而第二行报告 ruby​​ 1.9.3p194 作为当前解释器。

2. 在您的特定情况下，我会cd 进入项目文件夹，使用gem pristine --all 重建gemset，使用 重建项目依赖项>bundle update 然后尝试使用项目 binstub 重新运行命令:./bin/rake rspec。

3. 对我来说这似乎不是错误，但你应该时刻注意你使用的 ruby​​ 版本。使用 RVM，您可以指定默认的广泛系统 ruby​​ 版本和 gemset，但也可以根据需要指定任意数量的项目特定 ruby​​ 版本和 gemset，但这有时会导致麻烦。

希望对您有所帮助。
