使用 Windows 命令外壳无法识别 sass [英] sass not recognised using Windows command shell

问题描述

我已经在 Win 7 Enterprise 机器上安装了 ruby​​ 和 sass gem.我在整个过程中遇到了问题，不得不下载 gems 并从本地安装它们以避免其他问题.

I've installed ruby and the sass gem on a Win 7 Enterprise box. I've had issues throughout the process, and had to download the gems and install them from local to avoid other issues.

gem install --local sass-3.1.19.gem

我正在尝试 sass --watch styles.sass:styles.css 但我从命令行收到标准的 sass 无法识别错误.

I'm trying sass --watch styles.sass:styles.css but I get the standard sass isn't recognised error from the command line.

我对 ruby​​ 真的很陌生，所以我很可能错过了一步.

I'm really new to ruby so I could well have missed a step.

提前致谢

推荐答案

为了在不指定完整路径的情况下运行命令，您需要在 PATH 变量中包含程序的路径.

In order to run commands without specifying full path, you need to have the path to the program in you PATH variable.

因此，如果您的程序位于 C:\Programs\rubygems\gem\sass，则需要将 C:\Programs\rubygems\gem\ 添加到PATH.

So if your program is located in C:\Programs\rubygems\gem\sass you'll need to add C:\Programs\rubygems\gem\ to PATH.

为 Windows 命令行提示符添加文件夹到 PATH 的过程描述 这里.

The process of adding a folder to PATH for the Windows command line prompt is described here.

对于 Windows Powershell，请在 SO 上查看设置 Windows PowerShell 路径变量.
