如何为捆绑软件安装指定捆绑软件的版本

Question

当我尝试捆绑一个新项目的gemfile时，我得到了：

Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    bundler-audit was resolved to 0.6.0, which depends on
      bundler (~> 1.2)

    rails (~> 5.2) was resolved to 5.2.1, which depends on
      bundler (>= 1.3.0)

  Current Bundler version:
    bundler (2.0.2)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?

Could not find gem 'bundler (~> 1.2)', which is required by gem 'rails (~>
5.2)', in any of the sources.

因此，我运行gem install bundler '~> 1.2'。现在，当我运行gem list bundler时，我有这两个版本2.0.2、1.17.3我知道要将我的gemfile与版本1.17.3捆绑在一起但是，当我运行bundle _1.17.3_ install时，我得到：Could not find command "_1.17.3_"。我在这里做错了什么？我该如何解决？有没有一种方法可以直接在我的Rails项目中指定应该使用哪个版本的捆绑程序下载并解决依赖项？

先尝试gem install bundler -v 1.17.3，然后再尝试bundle _1.17.3_ install
