我目前正在使用Web开发类,我们正在使用Ruby on Rails.
我使用的是Ruby v1.9.2和Rails v3.1.1.
当我尝试执行'rails server'时,我的初始问题就出现了.
我会收到以下错误:
C:\Sites\rorProjects\basicRoRProject>rails server
C:/RailsInstaller/Ruby1.9.2/lib/ruby/gems/1.9.1/gems/execjs-1.2.13/lib/execjs/runtimes.rb:47:in `autodetect': Could not find a JavaScript runtime.
See https://github.com/sstephenson/execjs for a list of available runtimes.(ExecJS::RuntimeUnavailable)
我做了一些阅读,普遍的共识是安装宝石'execjs'和'therubyracer'.'execjs'安装得很好,但是当我尝试安装'therubyracer'时,我收到以下错误:
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
ERROR: Error installing therubyracer: ERROR: Failed to build gem native extension.
C:/RailsInstaller/Ruby1.9.2/bin/ruby.exe extconf.rb
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.
