Getting config.eager_load is set to nil while trying to run rails c in test

问题

I'm trying to run the rails (4.1.2) console

rails c RAILS_ENV=test

And I'm getting this:

> config.eager_load is set to nil. Please update your
> config/environments/*.rb files accordingly:
> 
>   * development - set it to false   * test - set it to false (unless
> you use a tool that preloads your test environment)   * production -

> `resolve_symbol_connection': 'RAILS_ENV=test' database is not
> configured. Available: ["development", "test", "production"]
> (ActiveRecord::AdapterNotSpecified)

Yet in my test.rb I have config.eager_load = false and my database.yml is ok (I ran rake db:schema:load RAILS_ENV=test without issues.

How can I solve this?

You need to declare the env before you run the commands:

RAILS_ENV=test bundle exec rails c

I get the same output on my computer:

> bundle exec rails c RAILS_ENV=test                                                                                                               ian@Ians-MacBook-Pro
config.eager_load is set to nil. Please update your config/environments/*.rb files accordingly:

  * development - set it to false
  * test - set it to false (unless you use a tool that preloads your test environment)
  * production - set it to true

but when I run as suggested:

> RAILS_ENV=test bundle exec rails c                                                                                                               ian@Ians-MacBook-Pro
Loading test environment (Rails 4.2.3)

As for Windows systems:

This should do:
```
rails c -e test
```
Or set the RAILS_ENV variable first:
```
set RAILS_ENV=test
rails c
```

回答3:

On Windows there is a glitch with RAILS_ENV. If you run

SET RAILS_ENV=development<SPACE>   <- with a space symbol after word "development"

then you will get the error:

config.eager_load is set to nil. Please update your config/environments/*.rb fil es accordingly:

when doing rails server webrick.

So make sure you do type without a trailing space (and no quotes)

SET RAILS_ENV=development<ENTER>

The same applies to all environments: test, production and development.

回答4:

Make sure you have your

production.rb
development.rb
test.rb

files in config/environments/ folder.

回答5:

Needs to set

config.eager_load = false

for config/environments/development.rb and test.rb or = true for production.rb (as default)
