运行捆绑安装
依赖 tzinfo-data (>= 0) 将不会被 Bundler 安装的任何平台使用。 Bundler 正在为 ruby​​ 安装，但依赖项仅适用于 x86-mingw32、x86-mswin32、x64-mingw32、java。要将这些平台添加到包中，请运行 bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java。

从 https://rubygems.org/ 获取 gem 元数据。
解决依赖关系...
无法在集合中找到满足 tzinfo-data (>= 0) 的规范。也许锁定文件已损坏？

我按照上面的建议进行操作：
捆绑锁 --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java

然后：
捆绑安装

一切似乎都很好。

当我尝试启动 Rails 服务器时，遇到以下错误：
C:\demo2>rails 服务器
=> Booting Puma
=> Rails 5.2.2 application starting in development
=> Run rails server -h for more startup options
退出

Answer 1

设法解决了问题。

步骤： 1. 在 Gemfile 中删除 ", platforms: [:mingw, :mswin, :x64_mingw, :jruby]" 为 "gem 'tzinfo-data', 平台: [:mingw, :mswin, :x64_mingw, :jruby]"
2. 运行 gem uninstall tzinfo-data
3.运行捆绑安装

重新安装 tzinfo-data 后，rails 服务器就可以启动了。

感谢您提供建议和努力帮助我解决此问题。

Answer 2

这不是一个真正的解决方案，但是当我尝试安装它时，在 Windows 上使用 rails 让我非常抓狂。 如果您使用的是 Windows，请尝试 AWS C9 或其他云开发平台，它会改变生活...

Answer 3

使用

gem 'tzinfo-data', '~> 1.2019', '>= 1.2019.2'

在您的 gemfile 中，根据 tzinfo-data gem page

不要忘记在它之后运行捆绑安装
