ruby-on-rails - 使用 less (2.2.1) 会引发需要 therubyracer 的错误(无法在 Windows 上安装 therubyracer)

我一直在努力让 twitter-bootstrap-rails gem 在我的 Windows 机器上工作,但在尝试安装“therubyracer” gem 时遇到了错误,该 gem 是旧版本的 less gem 的依赖项。

我认为升级到不依赖于 therubyracer 的 2.2.1 版本,但尽管如此,它似乎认为我仍然需要安装 therubyracer。这是我尝试启动 Rails 服务器“rails s”时得到的错误输出。

$ rails s
[WARNING] Please install gem 'therubyracer' to use Less.

这是我的 GemfileGemfile.lock文件。谁能帮我弄清楚如何告诉我的应用程序不需要安装“therubyracer”?

最佳答案

我强烈建议您关注 Daniel Kehoe 的优秀作品:
https://github.com/RailsApps/rails3-bootstrap-devise-cancan如果你还没有。

关于我在你的 Gemfile 中看到的唯一可疑的东西是里面有“rubyracer”。为什么会在那里?尝试删除它。别忘了bundle install当然,无论何时进行任何更改。

关于ruby-on-rails - 使用 less (2.2.1) 会引发需要 therubyracer 的错误(无法在 Windows 上安装 therubyracer),我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/12311306/
