ArgumentError：缺少必需的：bucket 选项答案

【问题标题】：ArgumentError: missing required :bucket optionArgumentError：缺少必需的：bucket 选项

【问题描述】：

我设置了所有环境变量。我使用heroku config 检查了它，但我仍然无法在开发环境中使用回形针 gem 和 aws s3 保存图像并收到ArgumentError: missing required :bucket option 错误。我什至尝试将AWS_BUCKET 更改为S3_BUCKET_NAME，但仍然没有成功。我已经解决了每一个堆栈溢出问题，我什至可以找到与该主题相关的远程问题，但仍然找不到解决方案。

【问题讨论】：

将所有这些 ENV 密钥添加到 secrets.yml 似乎有很多重复。它还引入了错误和间接来源，因为您不应该将 secrets.yml 检入 git。我会直接从您的初始化程序中使用ENV.fetch("SOME_KEY")。

【解决方案1】：

好吧，你有没有想过将环境变量添加到你的~/.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

• 重启终端

这解决了我的问题。
