我如下尝试了bundle install，但没有成功。
我尝试了很多在这里和那里找到的方法：
请注意，我是 Ruby 的新手，因此它可能是一些简单的解决方案。例如，我应该以某种方式解释捆绑软件以使用1.8.6。，但是我不知道如何使用它。
sudo bundle install
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break this
application for all non-root users on this machine.

Resolving dependencies...
Bundler could not find compatible versions for gem "bundler":
In Gemfile:
methadone was resolved to 1.3.0, which depends on
bundler
rails (~> 3.2) was resolved to 3.2.14, which depends on
bundler (~> 1.0)
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 (~> 1.0)', which is required by gem 'rails (~> 3.2)', in any of the sources.
更新2：
gem uninstall bundler
Select gem to uninstall:
1. bundler-1.0.10
2. bundler-2.0.1
3. All versions
> 2
You have requested to uninstall the gem:
bundler-2.0.1
rails-5.2.2 depends on bundler (>= 1.3.0)
rails-dom-testing-2.0.3 depends on bundler (>= 1.3, development)
If you remove this gem, these dependencies will not be met.
Continue with Uninstall? [yN]

解决方案： 下面的mjr答案是一个有效的解决方案，尽管降级Ruby也可以解决此问题。
答案 0 :(得分：2)
尝试运行bundle update json以强制更新json gem。如果这不起作用，则可以运行gem clean，删除Gemfile.lock，然后再次运行所有内容。
编辑：看来您的捆绑器版本与您的rails版本不兼容。您可以尝试通过运行以下命令来降低捆绑程序的等级：
gem install bundler --version '1.14.6' gem uninstall bundler --version '2.0.1' 这也是一个新项目吗？如果是这样，则应考虑使用滑轨5。滑轨3接近三个主要版本，而滑轨6的释放距离也不太远。这样也可以避免很多此类宝石问题。
