我们正在升级到最新的 ruby 版本 (2.2.3) 和最新的 rails 版本 (4.2.4)，我们无法通过此错误：

Answer 1

使用 RVM 创建 Gemset

rvm use 2.2.3@yourproject --create

之后安装捆绑器gem

gem install bundler

最后一步是捆绑安装

bundle install

Answer 2

该错误表明您正在使用系统 Ruby，而不是 RVM。您需要告诉 Pow 使用正确的 Ruby 版本。您需要创建一个 .rvmrc 文件指定要使用哪个 Ruby，还需要创建或编辑一个 .powrc 或 .powenv 文件来告诉 Pow 加载 RVM。见 Pow docs on using RVM.

Answer 3

如果您正在使用/升级到捆绑器 2，请查看此文档：

https://bundler.io/guides/bundler_2_upgrade.html

根据我的经验，基本上，您需要使用 RubyGems v2.5.0 或更高版本，否则如果您有 require 'bundler/setup'，您将看到 cannot load such file -- bundler/setup。如果您需要升级 rubygems，您可以通过以下方式进行：

gem update --system

希望对您有所帮助。谢谢
