Question

今天我们正在尝试安装旧项目＆＃34;由 rails3 ＆＃34;开发在我的Pc上输入命令后

bundle install 

rails s

它给了我错误

Please install gem 'therubyracer' to use Less.

然后我通过执行此步骤安装了 Gem therubyracer

首先激活我的代码编码

C:\>chcp 1252
Active code page: 1252

然后从此页面下载了Windows的Gem文件 https://github.com/hiranpeiris/therubyracer_for_windows

并输入命令

C:\>cd therubyracer_for_windows-master

C:\therubyracer_for_windows-master>gem install "therubyracer-0.11.0beta1-x86-min
gw32.gem"
Successfully installed therubyracer-0.11.0beta1-x86-mingw32
Parsing documentation for therubyracer-0.11.0beta1-x86-mingw32
Done installing documentation for therubyracer after 3 seconds
1 gem installed

C:\therubyracer_for_windows-master>cd..

C:\>cd sites

C:\Sites>cd siteFolder

C:\Sites>cd siteFolder> bundle install

C:\Sites\siteFolder>rails s

然后我发现自己得到了同样的错误！为什么？宝石现在安装，为什么我得到相同的错误???
