我正在尝试在 Windows 7 64 位中运行Ruby on Rails 项目，但由于gem bundle install，我无法做到这一点。therubyracer我在 Ubuntu 中开发它，但我需要在 Windows 7 计算机上将其作为生产运行。

经过搜索，我发现我应该在这里使用这个 gem：https ://github.com/eakmotion/therubyracer_for_windows/blob/master 。它似乎已安装therubyracer-0.11.0beta1-x86-mingw32在我的宝石中。正如gem install libv8 --version '3.11.8.17' on ruby​​ (windows)gem install libv8 -v '3.16.14.7' -- --with-system-v8中所建议的，我还使用 安装了 libv8

但是，即使我按照该 gem 的安装说明进行操作，bundle install仍然尝试安装therubyracergem（版本 0.12.1）。所以，我的问题是：如何使用手动安装的 therubyracer gem 运行 bundle install ？

版本：ruby 2.1.5，rails 4.1.8，使用 Rails Installer http://www.railsinstaller.org/en安装

Gemfile 的相关行：

gem "therubyracer"
gem "less-rails"
gem "twitter-bootstrap-rails"

如果我换取"therubyracer"，"therubyracer_for_windows"当Could not find gem 'therubyracer_for_windows (>= 0) ruby' in the gems available on this machine.我尝试执行bundle install.

的错误消息bundle install：

尝试在 gemfile 中指定版本，例如：

gem "therubyracer", "0.11.0beta1"

我至少已经成功地让捆绑安装以这种方式完成。
