无法降级打包商

Question

我尝试安装我克隆的项目。当我做“捆绑安装”我有以下消息：

$ bundle install 
Bundler could not find compatible versions for gem "bundler": 
In Gemfile: 
rails (= 3.0.0) ruby depends on 
bundler (~> 1.0.0) ruby 

Current Bundler version: 
bundler (1.6.2) 

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

所以，我做了以下内容：

gem uninstall bundler 
gem install bundler --version '1.0.0' 
Successfully installed bundler-1.0.0 
1 gem installed 

我做“捆绑安装”，和我保持具有相同的消息：

$ bundle install 
Bundler could not find compatible versions for gem "bundler": 
In Gemfile: 
rails (= 3.0.0) ruby depends on 
bundler (~> 1.0.0) ruby 

Current Bundler version: 
bundler (1.6.2) 

This Gemfile requires a different version of Bundler. 

Perhaps you need to update Bundler by running `gem install bundler`? 

看来我不能降级捆绑器到'1.0.0'版本，有什么想法吗？

Answer 1

如果您不需要捆扎机的多个版本，你卸载较新的版本：

$ gem uninstall bundler -v 1.6.2 

您也可以从捆绑的版本列表中进行选择，如果你有一个以上的：

$ gem uninstall bundler
