Question

我正在使用react-rails进行项目，但是当我运行时

bundle install

我得到了

Could not find json-1.8.1 in any of the sources

具体来说，这是整个错误

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

在stackoverflow上有关于此的各种帖子，并尝试了大多数＆＃34;解决方案＆＃39;但似乎没有一个对我有用，我也跑了

gem list | grep json

它说我有json gem via

 json (1.8.3)
 multi_json (1.10.1)

我试图阻止春天，更新宝石，＆amp;捆绑。我也跑了

rbenv rehash

无济于事，仍然会收到此错误，任何输入都会受到高度赞赏。

Answer 1

我上次在Ubuntu遇到了问题，我尝试安装此library并且也能正常运行。

sudo apt-get install libgmp3-dev

您可以参考文档：Failed to build gem json native extension

Answer 2

您可能希望降低ruby版本或颠覆json版本。请参阅：https://github.com/flori/json/issues/229

快速浏览一下json 1.8.1 gemspec并且至今没有提及ruby 2.3.0支持。

无法在任何来源中找到json-1.8.1
