如何使用环境变量设置启动Rails服务器?

I have the following command. I insert it on starting the rails server

我有以下命令。我在启动rails服务器时插入它。

VARIABLE=development rails s

How do I make this variable start automatically, without having to wright it myself every time?

So I would then just do this

我就这么做

rails s

and it would run automatically with that variable.

它会自动运行这个变量。

Bundle the dotenv-rails gem, then create a .env file with the content:

捆绑dotenv-rails gem，然后创建一个.env文件，内容如下:

VARIABLE=development

The gem picks up all variables from the file and sets them in your environment.

gem从文件中获取所有变量并在您的环境中设置它们。

If you don't need the variable to be variating, you should put this into initializers or on a helper class. If you're looking for enviroment, you don't need it because it's the default.

如果不需要变量进行变分，应该将其放入初始化器或helper类中。如果你在寻找环境，你不需要它，因为它是默认的。
