Ruby on rails 在windows 8.1上安装json时出错

我已经在

windows8.1x64

上安装了

rails4.2.3

和

ruby 2.2.2p95

。当我尝试运行“bundle install”时，安装失败，原因是

json-v1.8.3

。我已经安装了json版本1.8.1。当我运行rubygems更新命令时，它不会得到更新。如果我尝试单独运行

gem install json-v1.8.3

或

gem install json--platform=ruby--version=1.8.3

，我会得到以下错误

ERROR:  While executing gem ... (OptionParser::InvalidArgument)
invalid argument: -platform=ruby

C:\>gem install json --platform=ruby --version=1.8.3

看起来您可能安装了32位DevKit。尝试卸载您拥有的DevKit，下载并重新安装最新的64位DevKit。有关更多详细信息，请查看以下类似答案：

试试这个

gem安装--verboseJSON-v1.8.3
