ruby 更新到 2.5.0 后，需要 'bundler/setup' 引发异常

Question

在 ruby 2.5.0 更新后从 rails 应用程序调用 rake，不起作用。

$ rake

config/boot.rb

# frozen_string_literal: true

ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../Gemfile', __dir__)

require 'bundler/setup' # Set up gems listed in the Gemfile.

bundler/setup 不能要求。

乘客也有同样的问题，要启动 rails 应用程序：

有人对 ruby 2.5.0 有同样的问题吗？

Answer 1

修复很简单：将 RubyGems 更新至 2.7.4 版本

gem update --system

RubyGems 2.7.4 includes bug fixes.

Answer 2

遗憾的是，这里唯一的解决方案是将 Bundler 升级到 >= 1.16.1。请参阅 https://github.com/heroku/heroku-buildpack-ruby/pull/738 的示例，该示例在理论上是固定的，但不幸的是被 Heroku 阻止了。

升级到 Bundler 1.16.1+，您将不会再遇到任何问题。
