我目前正在尝试在终端中运行我的测试套件但是我收到以下错误：
Missing required arguments: aws_access_key_id, aws_secret_access_key (ArgumentError)
我在我的项目中使用Carrierwave，我很确定这是导致问题的原因。这是我的config / initializers / carrierwave.rb：
CarrierWave.configure do |config|
config.fog_credentials = {
:provider => 'AWS',
:aws_access_key_id => ENV['S3_ACCESS_KEY_ID'],
:aws_secret_access_key => ENV['S3_SECRET_ACCESS_KEY']
}
config.fog_directory = 'my_directory'
end
这是我的日志：

我需要做些什么才能摆脱这个错误并运行我的测试？

您需要设置环境变量S3_ACCESS_KEY_ID和S3_SECRET_ACCESS_KEY，以便它们在Rails中可用。您可以在终端中执行此操作：
export S3_ACCESS_KEY_ID=<your access key id>
export S3_SECRET_ACCESS_KEY=<your secret access key>
将它们添加到.bashrc或.bash_profile中，以便它们在您下次启动新shell时使用，或使用dotenv之类的内容使其专用于您的项目。

除了明显的解决方案之外，设置正确的ENV VARS，另外一个问题，我遇到的是 spring 。我正确设置了ENV vars，但是它们只是不被carrierwave.rb初始化程序识别。由于spring用于预加载应用程序以及 rake 和 rspec 等过程，因此没有考虑新创建的ENV VARS。重新启动弹簧固定了那个。

如果您使用figaro gem来管理您的AWS密码，您可以尝试：
- figaro heroku:set -e production，
- 然后写heroku config，你将检查当前的配置
如果一切正常，将列出您的AWS_ACCESS_KEY等。
