尝试在测试中运行rails c时，将config.eager_load设置为nil

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

我正在尝试运行rails（4.1.2）控制台

rails c RAILS_ENV=test

And I'm getting this:

我得到了这个：

> 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
> 
> /Users/xxxxxx/.rvm/gems/ruby-2.2.2/gems/activerecord-4.1.12/lib/active_record/connection_adapters/connection_specification.rb:257:in
> `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.

然而在我的test.rb中我有config.eager_load = false并且我的database.yml没问题（我运行了rake db：schema：加载RAILS_ENV = test没有问题。

How can I solve this?

我怎么解决这个问题？

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

您需要在运行命令之前声明env：

RAILS_ENV=test bundle exec rails c

I get the same output on my computer:

我在计算机上得到相同的输出：

> 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:

但是当我按照建议跑步时：

> RAILS_ENV=test bundle exec rails c                                                                                                               ian@Ians-MacBook-Pro

As for Windows systems:

至于Windows系统：

This should do:

这应该做：
```
rails c -e test
```
Or set the RAILS_ENV variable first:

或者首先设置RAILS_ENV变量：
```
set RAILS_ENV=test
rails c
```

#3

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

在Windows上，RAILS_ENV出现故障。如果你跑

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

then you will get the error:

然后你会得到错误：

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

config.eager_load设置为nil。请相应地更新您的config / environments / * .rb文件：

when doing rails server webrick.

当做rails服务器webrick时。

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

因此，请确保您键入时没有尾随空格（并且没有引号）

SET RAILS_ENV=development<ENTER>

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

这同样适用于所有环境：测试，生产和开发。
