我正在开发一个Rails 5.2应用程序，我已经安装和设置了active_storage，但是，我似乎无法编辑或显示rails凭据。
这是错误的输出

但是，当我生成新应用程序时，我可以编辑和显示凭据。所以不确定这个应用程序的问题，因为我没有更改主密钥。

我也得到了

注释您使用凭据并运行EDITOR="atom --wait" rails credentials:edit的行(并在编辑后取消注释它们(。如果这不起作用，请删除 credentials.yml.enc，然后重试。
移动或删除 credentials.yml.enc 和 master.key 并重新运行rails credentials:edit。这对我有用。
我也有同样的问题。我发现运行EDITOR="atom --wait" rails credentials:edit是不够的。
如果在源代码中设置Rails.application.credentials.some_api_key而没有先在加密凭据中定义它，则将无法编辑凭据文件，甚至无法查看它。这可能是因为必须运行整个应用程序才能解密凭据。
