这是我的宝石文件

#gem 'rails', '3.2.9'

gem 'thin'

#  gem 'activerecord-postgresql-adapter'
  gem 'pg'
  gem 'newrelic_rpm'

end

#gem 'execjs'

#gem 'node'

有谁知道如何修理它？

如果 RUBY_PLATFORM =~ /mingw/` 已验证gem 'therubyracer and gem 'libv8', '3.3.10.4''，请将其从当前行中删除并添加到下方？gem 'exception_notification'. is this检查是否安装了 ruby​​racer gem。运行 bundle 看看问题是否存在
