尝试在测试中运行rails c时，将config.eager_load设置为nil
我正在尝试运行rails（ 4.1.2 ）控制台
rails c RAILS_ENV=test
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)
然而在我的test.rb我有config.eager_load = false并且我的database.yml没问题（我运行了rake db:schema:load RAILS_ENV=test没有问题。
我怎么解决这个问题？
您需要在运行命令之前声明env：
RAILS_ENV=test bundle exec rails c
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
但是当我按照建议跑步时：
> RAILS_ENV=test bundle exec rails c ian@Ians-MacBook-Pro Loading test environment (Rails 4.2.3)
至于Windows系统：
-
这应该做：
rails c -e test -
或者首先设置
RAILS_ENV变量：set RAILS_ENV=test rails c
在Windows上， RAILS_ENV出现故障。 如果你跑
SET RAILS_ENV=development <- with a space symbol after word "development"
然后你会得到错误：
config.eager_load is set to nil. Please update your config/environments/*.rb fil es accordingly:
当做rails server webrick 。
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
这同样适用于所有环境：测试，生产和开发。
确保你有
-
production.rb
-
development.rb
-
test.rb
config / environments /文件夹中的文件。
