尝试使用 mysql 数据库启动 Rails 项目时出现 Mysql 错误

问：

我正在尝试在 Windows 系统上创建一个新的 Ruby Rails 项目

我已经安装了 Rails v 7.1.1

然后我跑rails new myRailsProject -d mysql

但是，会发生错误：

An error occurred while installing mysql2 (0.5.5), and Bundler cannot continue.

In Gemfile:
  mysql2
         run  bundle lock --add-platform=x86_64-linux

Run `bundle install` to install missing gems.
       rails  turbo:install stimulus:install

Run `bundle install` to install missing gems.

然后我尝试按照在线论坛运行Bundle install

我得到：Could not locate Gemfile

rails 目录已经创建好了，所以我使用 cd 进入它，然后再次运行。我仍然收到一个错误：cd myRailsProjectbundle install

An error occurred while installing mysql2 (0.5.5), and Bundler cannot continue.

In Gemfile:
  mysql2

我不确定出了什么问题。我的项目的 Rails 目录已创建，尽管该项目似乎没有使用 mysql，而且我无法运行 .bundle install
