我最近从http://railsinstaller.org/en安装了Ruby。 这包括Ruby on Rails和Ruby dev-kit。
现在我正在尝试安装rubocop,但它无法正常工作:
C:\Windows\System32>gem install rubocop
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
The system cannot find the path specified.
ERROR: Error installing rubocop:
