我是node.js的新手，我已经安装了node.js并使用command npm -v检查了它的工作正常，我尝试测试它构建开源项目
github https://github.com/quran/quran.com-frontend
运行该项目的命令是
npm run dev
我收到这个错误
C:\Users\Acer\Desktop\quran.com-frontend-master\quran.com-frontend-master>npm run dev

在 Windows 上，默认情况下不识别“env”命令；在那里我找到了两个选择：
- 使用另一个命令代替，例如：
set VARIABLE_NAME=custom name
- 安装cygwin并将其安装路径设置为windows环境变量。安装后您可以从命令行使用：
env VARIABLE_NAME=custom name
以下是 cygwin 安装详细信息的链接：https://www.howtogeek.com/howto/41382/how-to-use-linux-commands-in-windows-with-cygwin/
