ruby-on-rails - 捆绑安装 - 需要 Ruby 版本 >= 1.9.2？

Question

我刚开始使用 Ruby on Rails 进行一些开发，并尝试在本地运行该应用程序。该应用程序在安装了 Ruby 1.8.7 的生产环境中运行。

我在我的计算机上安装 RVM，默认使用 Ruby 1.8.7。但是，当我尝试运行 bundle install 时，我收到以下错误消息:

Gem::InstallError: mime-types requires Ruby version >= 1.9.2.
An error occurred while installing mime-types (2.1), and Bundler cannot continue.
Make sure that `gem install mime-types -v '2.1'` succeeds before bundling.

我尝试在我的 Gemfile 中寻找 mime-types 但找不到；这让我相信这是对另一个 gem 的依赖。

奇怪的是，生产服务器也设置了 Ruby 1.8.7，所以我不太确定应用程序最初是如何设置运行的，尤其是当 mime-types 需要 Ruby 版本时 > = 1.9.2 运行。

我在生产服务器上的 Gemfile.lock 中找不到 mime-types，因此无法确定是什么 gem 试图包含它.

有谁知道如何让这个应用程序在本地运行以便我可以开始开发？

我真的没有很多 Ruby 或 Rails 的经验。

提前致谢。

Gem::InstallError: mime-types requires Ruby version >= 1.9.2.
An error occurred while installing mime-types (2.1), and Bundler cannot continue.
Make sure that `gem install mime-types -v '2.1'` succeeds before bundling.

Answer 1

如果您升级到 OSX 10.9 Mavericks，这可能是由旧版本的 bundler 的剩余可执行文件引起的，该 bundler 以前与 ruby​​ 1.8 一起安装并且仍然存在，因为尚未为 ruby​​ 2.0 安装 bundler 。

通过安装 bundler 修复它:

sudo gem install bundler

这是一项完整的调查，证实这确实是问题的原因:
