tzinfo-data 存在但未见？

Question

我正在学习 Rails 课程，并收到以下错误，告诉我安装 tzinfo-data gem。但是，gem 已安装。它在我的 gemfile 中。我可以在 Ruby 目录中找到该文件夹​​。为什么这仍然告诉我安装 tzinfo-data？

命令行响应和 gemfile 如下：

C:\Users\KevinLamb\Documents\sites\demo_project>rails db:schema:dump
rails aborted!
TZInfo::DataSourceNotFound: tzinfo-data is not present. Please add gem 'tzinfo-data' to your Gemfile and run bundle install
C:/Users/KevinLamb/Documents/sites/demo_project/config/environment.rb:5:in `<main>'

Caused by:
TZInfo::DataSources::ZoneinfoDirectoryNotFound: None of the paths included in TZInfo::DataSources::ZoneinfoDataSource.search_path are valid zoneinfo directories.

Bundler 中存在一个错误，这意味着没有与 Windows 上的 64 位 Ruby 3.1 匹配的有效平台值。

在gem "tzinfo-data", platforms: %i[ mingw mswin x64_mingw jruby ]您的Gemfile（或任何platforms选项）中，Bundler 将从捆绑包中排除 tzinfo-data，您将收到TZInfo::DataSourceNotFound错误消息。

platforms解决方案是从 Gemfile 中的 tzinfo-data 行中删除该选项，然后运行bundle install：

gem 'tzinfo-data'
