Heroku rails console does not start any more
提问by Micha
I have an issue with running the rails console at heroku (cedar-stack). Each of the following commands heroku run console, heroku run rails console, heroku run bundle exec rails console results in the following error-message:
我在 heroku (cedar-stack) 上运行 rails 控制台时遇到问题。以下每个命令 heroku run console、heroku run rails console、heroku run bundle exec rails console 都会导致以下错误消息：
Running bundle exec rails consoleattached to terminal... up, run.8155
运行bundle exec rails console附加到终端... up, run.8155
Abort testing: Your Rails environment is running in production mode!
中止测试：您的 Rails 环境正在生产模式下运行！
This error-message is a little bit confused. What kind of test tries heroku to start? I just want to fire up the console, which had worked fine 4 weeks ago.
这个错误信息有点混乱。什么样的测试尝试 heroku 启动？我只想启动 4 周前运行良好的控制台。

For Cedar Stack and later:
对于 Cedar Stack 及更高版本：
heroku run rails console --app <app name>
Previous stacks could use this command:
以前的堆栈可以使用此命令：
heroku run console --app <app name>

If you have multiple environments (staging / production / etc) you need this command:
如果您有多个环境（暂存/生产/等），则需要此命令：
heroku run -a app-name console
If you only have a single environment and never setup staging or other environments you can just run:
如果您只有一个环境并且从不设置暂存或其他环境，则可以运行：
heroku run console

I was with the same problem and I decided to do this and it worked
我遇到了同样的问题，我决定这样做并且它奏效了
$ heroku run bash
$ cd bin
~/bin $ ruby rails console

For some reason you need to explicitly define the console process in the Procfile:
出于某种原因，您需要在以下内容中明确定义控制台进程Procfile：
# Procfile
web: script/rails server -p $PORT
console: script/rails console

You should just use heroku run consoleas others have answered.
你应该heroku run console像其他人回答的那样使用。
Heroku only runs in one environment at a time, which is configured by the RAILS_ENV and RACK_ENV environments variables.
Heroku 一次只在一个环境中运行，这是由 RAILS_ENV 和 RACK_ENV 环境变量配置的。
When you connect, the console will use the correct environment automatically.
连接时，控制台将自动使用正确的环境。
