$bundle install

Installing ffi 1.9.10 with native extensions

Bundle complete! 14 Gemfile dependencies,68 gems now installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.
$bundle show ffi
/Users/me/.rvm/gems/ruby-2.2.2/gems/ffi-1.9.10
$rails c
Could not find ffi-1.9.10 in any of the sources
Run `bundle install` to install missing gems

我尝试在我的Gemfile中放置“gem’ffi’,’1.9.10’”.

我尝试删除我的Gemfile.lock并重复此过程.

我试过捆绑exec rails c.

我尝试了gem install ffi –version 1.0.11,这似乎是childprocess-0.5.6的依赖.

这些尝试都没有任何区别.有任何想法吗？
