参数错误：缺少必需：存储桶选项

问题描述：

我有我所有的环境变量设置。我用heroku config进行了检查，但仍然无法在开发环境中使用回形针gem和aws s3保存图像，并且收到ArgumentError: missing required :bucket option错误。我甚至尝试将AWS_BUCKET更改为S3_BUCKET_NAME，但仍然没有成功。我已经经历了所有可能与主题相关的堆栈溢出问题，但仍无法找到解决方案。参数错误：缺少必需：存储桶选项

将所有这些ENV密钥添加到secrets.yml中似乎有很多重复。它还引入了一个错误和间接的来源，因为你不应该将secrets.yml检查到git中。我只是直接从初始值设定项中使用ENV.fetch（“SOME_KEY”）。 – max

那么，你有没有想过到环境变量添加到您的~/.bash_profile

export AWS_ACCESS_KEY_ID="KJAHSDH9HD0SAD89H" 
export AWS_BUCKET="staging_value" 
export AWS_SECRET_ACCESS_KEY="HASDF78H/JHIUDHSHHS8DH7USD7CH"

•然后运行source .bash_profile

•重新启动终端

这解决了这个问题对我来说。
