运行捆绑
安装Bundler 正在安装的任何平台都不会使用依赖项 tzinfo-data (>= 0)。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捆绑包中，请运行bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java。从https://rubygems.org/
获取 gem 元数据............
从https://rubygems.org/获取 gem 元数据。
正在解决依赖关系...
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？
我按照上面的建议操作：
bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java
然后：
捆绑安装
一切看起来都很好。

设法解决了这个问题。
步骤： 1. 在 Gemfile 中删除“gem 'tzinfo-data',platforms: [:mingw, :mswin, :x64_mingw, :jruby]”
2. 运行 gem uninstall tzinfo-data
3. 运行捆绑安装
重新安装回tzinfo-data后，rails服务器就可以启动了。
感谢您的建议和努力帮助我解决这个问题。
