RVM 在 ruby-2.4.0 上设置并且我创建了具有版本的新应用程序，

gem 'rails', '4.2.6'

我更新了 bundler ，使用

gem update --system
gem install bundler
bundle version
# Bundler version 2.0.1 (2019-01-04 commit d7ad2192f)

但是我在 bundle install 时遇到以下错误，

Fetching gem metadata from https://rubygems.org/.............

Resolving dependencies...
Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    rails (= 4.2.6) was resolved to 4.2.6, which depends on
      bundler (< 2.0, >= 1.3.0)

  Current Bundler version:
    bundler (2.0.1)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?

Could not find gem 'bundler (< 2.0, >= 1.3.0)', which is required by gem 'rails (= 4.2.6)', in any of the sources.

它要求我提供较低版本的 bundler ，为什么？上面应该怎么解决？

最佳答案

安装任何版本为 (= 1.3.0) 的 bundler 。

例如

gem install bundler -v 1.17.3

然后

bundle _1.17.3_ install

它应该适合您的情况。
