Ruby/Rails 弃用警告：“--rc”的预期字符串默认值；得到错误布尔

问题描述

我正在学习 rails，当我尝试在 wsl 上运行服务器 rails s -b 0.0.0.0 时，我收到一个错误：

Deprecation warning: Expected string default value for '--rc'; got false (boolean).
This will be rejected in the future unless you explicitly pass the options `check_default_type: false` or call `allow_incompatible_default_type!` in your code
You can silence deprecations warning by setting the environment variable THOR_SILENCE_DEPRECATION.
Usage:
  rails new APP_PATH [options]...

我试过 gem thor 到 0.19.1 但错误是一样的。

我该如何解决？

观察： ruby 2.5.1p57 (2018-03-29 修订版 63029) [x86_64-linux] 导轨 4.2.5 wsl 上的 ubuntu 18.04

未创建 Gemfile.lock。
