【问题描述】：
当我昨天可以在本地运行 rails 项目时。
但是今天我无法运行项目，出现以下问题。
我什么都没做。 我正在使用 Spring 2.1.0
$ rails s
=> Booting Puma
=> Rails 5.2.4.1 application starting in development
=> Run `rails server -h` for more startup options
Exiting
You've tried to invoke Spring when it's already loaded (i.e. the Spring constant is defined).
This is probably because you generated binstubs with Spring 1.0, and you now have a Spring version > 1.0 on your system. To solve this, upgrade your bundle to the latest Spring version and then run `bundle exec spring binstub --all` to regenerate your binstubs. This is a one-time step necessary to upgrade from 1.0 to 1.1.
Here's the backtrace:

我知道这个问题是一个众所周知的问题。
我已经研究过要解决的问题，但我无法解决。
以前有人遇到过这个问题吗？
【问题讨论】：
-
如果你执行它的建议？ bundle exec spring binstub --all
-
试试
bin/spring stop。 -
@Fernand，这对我没有帮助。

@HardikUpadhyay，这对我没有帮助。
