ruby-on-rails – rb_gc()上的跨线程冲突

我跑的时候

rails s

我收到了错误

[BUG] cross-thread violation on rb_gc()

我找到了许多与此问题有关的链接.有one on StackOverflow,但它并没有真正给出答案.最有希望的答案是on the RVM site：

In every case of this I have seen thus far it has always ended up
being that a ruby gem/library with C extensions was compiled against a
different ruby and/or architecture than the one that is trying to load
it. Try uninstalling & reinstalling gems with C extensions that your
application uses to hunt this buggar down.

这是相当有用的,但我的Ruby-fu不够强大,无法知道哪些宝石有C扩展,哪些我应该尝试重新安装.关于该主题的其他几个链接似乎表明json gem有问题,所以我尝试按照建议的解决方案.

gem uninstall json 
gem install --platform=ruby

这对我来说并没有真正改变任何东西 – 在尝试启动Rails环境时我仍然得到完全相同的错误.

如何追踪此问题？
