Question

最近我已经安装了rbenv并指定了ruby到2.3.1并且导航到5.1.1但我无法运行我的项目因为我得到了：

Ignoring json-2.1.0 because its extensions are not built.  Try: gem pristine json --version 2.1.0
Ignoring nokogiri-1.8.1 because its extensions are not built.  Try: gem pristine nokogiri --version 1.8.1
Ignoring unf_ext-0.0.7.4 because its extensions are not built.  Try: gem pristine unf_ext --version 0.0.7.4
Ignoring yajl-ruby-1.3.1 because its extensions are not built.  Try: gem pristine yajl-ruby --version 1.3.1
/var/lib/gems/2.3.0/gems/bundler-1.16.1/lib/bundler/spec_set.rb:88:in `block in materialize': Could not find unf_ext-0.0.7.4 in any of the sources (Bundler::GemNotFound)

from /var/lib/gems/2.3.0/gems/bundler-1.16.1/lib/bundler/spec_set.rb:82:in `map!'
...
from /home/alex/pnv/vendor/bundle/ruby/2.3.0/gems/spring-2.0.2/bin/spring:49:in `<main>'

我跑了：

bundle install

安装成功通过，但是......现在我得到了：

/home/alex/pnv/vendor/bundle/ruby/2.3.0/gems/ffi-1.9.18/lib/ffi.rb:6:in `require': incompatible library version - /home/alex/pnv/vendor/bundle/ruby/2.3.0/gems/ffi-1.9.18/lib/ffi_c.so (LoadError)

    from -e:1:in `<main>'

我不知道如何解决这个问题。任何帮助表示赞赏！

更新1 ：最后，我找到了邪恶的bug的来源 - 尽管如此，我指定了Rails 5.1.1，当我运行rails new app_name时，它会安装5.1.6！并且似乎它使用5.1.6 gem依赖...仍然不知道如何解决而不是升级到＆gt; = 5.1.6

Answer 1

将以下行添加到Gemfile中。

gem 'rails', '5.1.1'

运行bundle install

安装rbenv时如何解决gem依赖关系？
