我刚刚将我的 Rails 应用程序从 v5.2.3 升级到 v6.0.0.beta3。我正在使用 Daterangepicker v3.0.3 gem，它似乎与 Rails 6.x 不兼容。我的应用程序依赖于 gem，如果可能的话，我真的很想坚持使用它（如何？），如果没有，那么什么 gem 可以替代它？

我将 Rails gem 版本更改为 edge 并运行bundle update。它输出以下内容：

Bundler could not find compatible versions for gem "actionpack":
  In Gemfile:
    jquery-datatables-rails (~> 3.4) was resolved to 3.4.0, which depends on
      actionpack (>= 3.1)

  In Gemfile:
    countries

    country_select (~> 3.1) was resolved to 3.1.1, which depends on

Bundler could not find compatible versions for gem "railties":
  In Gemfile:
    bootstrap-daterangepicker-rails (~> 3.0, >= 3.0.3) was resolved to 3.0.3, which depends on
      railties (>= 4.0, < 5.3)

    coffee-rails (~> 4.2) was resolved to 4.2.2, which depends on

    devise (~> 4.5) was resolved to 4.6.2, which depends on
      railties (>= 4.1.0, < 6.0)

    jquery-rails (~> 4.3, >= 4.3.3) was resolved to 4.3.3, which depends on
      railties (>= 4.2.0)

    momentjs-rails (~> 2.17, >= 2.17.1) was resolved to 2.20.1, which depends on
      railties (>= 3.1)

    rails (~> 6.0.0.beta3) was resolved to 6.0.0.beta3, which depends on
      railties (= 6.0.0.beta3)

    sass-rails (~> 5.0) was resolved to 5.0.7, which depends on
      railties (>= 4.0.0, < 6)

    web-console (>= 3.3.0) was resolved to 3.7.0, which depends on
      railties (>= 5.0)

我注释掉了我的 Daterangepicker gem，并且包更新完美无缺。我看到宝石取决于railties < 5.3, >= 4.0。Rails v6 使用 railties > v4，这可能是它抛出错误的原因。我能做些什么呢？

先感谢您。

值得注意的是，sass-rails该railties版本也已锁定< 6。

如果这种情况发生了变化，我会感到惊讶，因为 Rails 世界中的大多数东西都转向webpacker来处理所有前端（曾经存在于资产管道中的所有东西）。值得一看react-rails 之类的东西，它可以让你使用react-bootstrap-daterangepicker。

要么，要么你总是可以 PR/fork Daterangepicker gem。虽然，基于提交和长期 PR 的（内）频率，我认为你可能会更幸运地走 webpacker 路线。

我不建议您使用带有 javascript 依赖项的 gem，因为 Rails 正在移动（就像在 Rails 6 上所做的那样）使用 Webpack 作为 CSS 和 Javascript 的预处理器。除了使用 Vue.js、Angular 和 React 等框架之外，在 Rails 上处理 Javascript/Jquery 依赖项的更好解决方案是使用 Webpack 全局加载 Jquery。这样，您可以在您的应用程序中使用 bootstrap 和 bootstrap-datepicker，因为它们都以 yarn/npm 包的形式存在。您还可以让 Jquery 函数与您的应用程序一起使用。

这是关于使用 Webpack 全局设置 Jquery 的 SO 链接

我知道这不是最好的解决方案，但我是这样解决的：

Gemfile：

gem 'bootstrap-daterangepicker-rails', git: 'https://github.com/jordanbrock/bootstrap-daterangepicker-rails.git', branch: 'master'

如果你害怕指向master，你也可以像这样指向最新的commit：

gem 'bootstrap-daterangepicker-rails', git: 'https://github.com/jordanbrock/bootstrap-daterangepicker-rails.git', ref: '6cade9deedfca1e6e55ce68b7c828f001e13f995'
