今天我试图使octopress在Windows上运行，并且一切正常，直到rake install，因为然后我收到了以下消息：
C:\octopress>rake install --trace
## Set the codepage to 65001 for Windows machines
rake aborted!
Errno::ENOENT: No such file or directory - chcp 65001

我已经尝试过重新安装gem，以管理员和普通用户身份运行它。尝试在Windows 10下安装octopress时，是否还有其他人遇到相同的问题？
Edit：//我发现该错误仅属于命令“ chcp”，而该命令在Windows 10 x64上不可用。有什么方法可以使此命令在Windows 10 x64上运行？
将Windows 10升级到最新版本解决了该问题。
