推荐答案

检查你的 gemfile 你会看到这样的gem 'tzinfo-data'，平台:[:mingw, :mswin] 或gem 'tzinfo-data', 平台: [:mingw, :mswin, :x64_mingw]

check your gemfile you will see there like this gem 'tzinfo-data', platforms: [:mingw, :mswin] OR gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw]

如果你有 gem 'tzinfo-data'，平台:[:mingw, :mswin, :x64_mingw]然后将其替换为gem 'tzinfo-data', 平台: [:mingw, :mswin]

if you have gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw] then replace this with gem 'tzinfo-data', platforms: [:mingw, :mswin]

然后保存文件并启动包更新命令.

and after that save file and fire bundle update command .
