Question

我正在尝试在我的本地计算机上运行一个开源Web应用程序（Ubuntu 15.10）。当我运行bundle命令时，我得到了这个

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

current directory:
/home/yesh/.rbenv/versions/2.4.0/lib/ruby/gems/2.4.0/gems/json-1.8.3/ext/json/ext/generator

Gem files will remain installed in
/home/yesh/.rbenv/versions/2.4.0/lib/ruby/gems/2.4.0/gems/json-1.8.3 for
inspection.

An error occurred while installing json (1.8.3), and Bundler cannot
continue.
Make sure that `gem install json -v '1.8.3'` succeeds before bundling.

所以我尝试了gem install json -v '1.8.3'但又得到了与上面相同的错误消息。请帮忙解决这个问题。

Answer 1

我认为你可以解决你的问题：

sudo apt-get install libgmp3-dev

如果上面的命令没有解决你的系统，你可以尝试安装这个命令：

sudo apt-get install libgmp-dev

您可以参考json-1.8.3 Gem::Ext::BuildError

因为你的ruby版本是2.4.0。ruby版本与json 1.8.3不兼容。您可以尝试在Gemfile中添加此行：

gem 'json', github: 'flori/json', branch: 'v1.8'

Answer 2

看起来你的Ruby版本与Project的Ruby版本不同。 JSON仅支持从2.0.0版开始的Ruby中的Integer统一。以及 - 也许一些列出的宝石依赖于json (~> 1.8)。在Gemfile中注释掉这个gem并运行bundle install或降级Ruby。 Read more about this issue

在Ubuntu上安装带有ruby 2.4.0的json 1.8.3时出错
