ruby-on-rails - Rails 5.0.2 与 bundler 2.0.1 不兼容

Question

我目前正在运行带 bundler 的 Rails 5.0.2(<2.0，>=1.3.0)。今天早上，当我运行“gem install bundler”时，它最终安装了现在与 Rails 5.0.2 不兼容的 bundler 2.0.1。我想知道我是应该升级我的 Rails 版本还是降级 bundler 版本。请在下面查看我的 jenkins 构建的日志。

gem install bundler
Successfully installed bundler-2.0.1

1 gem installed
bundle install
The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

Resolving dependencies...
Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    rails (~> 5.0.2) was resolved to 5.0.2, which depends on
      bundler (< 2.0, >= 1.3.0)

  Current Bundler version:
    bundler (2.0.1)
This Gemfile requires a different version of Bundler.
