Missing `secret_key_base` for 'development' environment, set this value in `config/secrets.yml`

Hi,

im newie with Ruby and Rail. Right now im following Book Two from Daniel Kehoe. I stucked with SECRET_KEY_BASE.

Ruby -v : 2.4.1
Rails -v: 5.1.6

After I restart Puma:

Puma caught this error: Missing secret_key_base for 'development' environment, set this value in config/secrets.yml (RuntimeError)

I changed few files like: .bash_profile; .profile and ofc. secrets.yml. But still without change

I found more then one .bash_profile. So, I dont know which one is the right one.
After I use command echo $SECRET_KEY_BASE. I'm getting empty line.

secrets.yml

Can You please help me. I followed like 10 or more forums but still without result.
THANK YOU

If working in development, i.e on your local machine you don't need the secrets or other environment variables set within your bash_profile.

As the error states, you can set it within the config/secrets.yml file:

development:
secret_key_base: my-secret-key

The way environment variables work in the production environment would be...

You'd have this in your config/secrets.yml file:

production:
secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>

And in your bash_profile on your production server you'd have the line:

export SECRET_KEY_BASE="my-secret-key-here"

So, when rails reads the secrets.yml file you're basically saying "you can find my secret key in the environment variable SECRET_KEY_BASE"

Thank You for answer.

Still the same problem. So I decided to start this project from begining. I did only one diffrence. Previously I create new secret key base via command $ rails secret (I deleted the origin one). And now in the new project I used the origin one created with new rails app ($ rails new . ). And now it works. So probably isn't so easy just generate new key and replace the old one (I restart server and terminal).
