安装捆绑包后，Rails服务器未加载gem

Question

我没有对Rails应用程序进行任何更改，但是当我运行rails s ，它给了我这个错误：

我已经运行了可以成功运行的bundle install ，但是仍然看到上述错误。

这可能是我的Rails以及它在哪里寻找宝石的配置问题吗？ 如果是这样，我如何设置它以在./vendor/gems/ruby/2.4.0查找宝石？

我还尝试在列出的各种gem install gem。

这是我的Ruby和Rails所在的位置：

$ which ruby
/usr/local/bin/ruby

$ which -a ruby
/usr/local/bin/ruby
/usr/local/bin/ruby
/usr/local/bin/ruby
/usr/bin/ruby

$ which rails
/usr/local/bin/rails

$ which -a rails
/usr/local/bin/rails
/usr/local/bin/rails
/usr/local/bin/rails
/usr/bin/rails

$ ruby -v
ruby 2.4.2p198 (2017-09-14 revision 59899) [x86_64-darwin16]

$ rails -v
Rails 5.0.6

我在OSX 10.12.6-Sierra上。

宝石文件：

source 'https://rubygems.org'

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
  "https://github.com/#{repo_name}.git"
end

所以我也尝试创建一个全新的rails应用程序并运行rails，这也给我一个类似的错误，如下所示：

/usr/local/lib/ruby/gems/2.4.0/gems/sqlite3-1.3.13/lib/sqlite3.rb:6:in `require': cannot load such file -- sqlite3/sqlite3_native (LoadError)

删除所有宝石的宝石版本，使您看到此错误。 例如，将gem'uglifier'，'> = 1.3.0'更改为gem'uglifier'，对所有产生错误的宝石执行此操作。 如果不起作用，请不要捆绑安装，只需捆绑（仅适用于旧版本的捆绑器）新版本的捆绑器（即bundler pre--）捆绑并安装，而旧版本则捆绑安装。
