我应该关注纱线警告吗？

Question

OS: Mac Mojave 10.14.3    

我的Gemfile：

source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }
ruby '2.6.0'
gem 'rails', '~> 5.2.2'
gem 'mysql2', '>= 0.4.4', '< 0.6.0'
gem 'puma', '~> 3.11'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'webpacker'
gem 'coffee-rails', '~> 4.2'
gem 'turbolinks', '~> 5'
gem 'jbuilder', '~> 2.5'
gem 'bootsnap', '>= 1.1.0', require: false
group :development, :test do
  gem 'byebug', platforms: [:mri, :mingw, :x64_mingw]
end
group :development do
  gem 'web-console', '>= 3.3.0'
  gem 'listen', '>= 3.0.5', '< 3.2'
  gem 'spring'
  gem 'spring-watcher-listen', '~> 2.0.0'
end
group :test do
  gem 'capybara', '>= 2.15'
  gem 'selenium-webdriver'
  gem 'chromedriver-helper'
end

bundle install不会产生任何错误。

如果我做：

yarn add moment

这是我看到的：

yarn add v1.13.0

我试过谷歌搜索这些错误，但我没有走得太远。我确实得到了“成功保存了一个新的依赖，但我无法想象这将成功运行所有这些警告。任何想法？

Answer 1

对等依赖项是项目假定您已安装的依赖项。您可以安装它们以使警告消失。您需要手动安装它们，只需对所需的依赖项执行yarn add。

它在消息中是正确的，它说明了你缺少哪些deps（caniuse-lite，webpack）
