therubyracer不在Windows上安装 [英] therubyracer not installing on Windows

问题描述

当试图安装gem时，我得到以下错误：

  C：\xampp\htdocs\\mg> gem安装therubyracer 
暂时增强PATH以包含DevKit ... 
构建本机扩展。这可能需要一段时间... 
错误：安装therubyracer时出错：

我已经试过在Gemfile中添加这个元素

  gem'therubyracer'，
 gem'less-rails 
  

试过

  gem卸载libv8 
 gem install therubyracer -v = 0.10.1 
  

以上所有内容都失败了，并且therubyracer从未安装过。 不幸的是， ruby​​racer gem在Windows上不起作用。看到这个

When attempting to install gem I am getting following error

I have tried adding this in Gemfile

gem 'therubyracer',
gem 'less-rails

Tried

gem uninstall libv8
gem install therubyracer -v=0.10.1

Everything above failed and therubyracer never installed.

解决方案

Unfortunately, the rubyracer gem does not work on Windows. See this
