我使用Windows10。我刚刚安装了Laravel 7,并使用以下命令创建了一个新项目:
composer create-project --prefer-dist laravel/laravel briscola
然后我在app.scss文件中添加了以下代码以呈现红色背景:
body {
background-color: red;
}
然后我运行以下代码以使用当前的app.scss文件:
npm run dev
不幸的是,先前的命令不起作用,我看到了以下错误:
> @ dev C:\xampp\htdocs\briscola
> npm run development

> @ development C:\xampp\htdocs\briscola

您对这个错误以及如何解决有任何想法吗?

实际尝试一下
rm -rf node_modules
rm package-lock.json yarn.lock
npm cache clear --force
然后
npm install cross-env
npm install
最后
npm run dev

我在这个线程(以及其他线程)中做了所有被接受的答案,但无济于事。真正解决了我关于这个问题的问题是:
这些步骤成功了,如果以上答案不起作用,您可以尝试。
现在当我重新检查我的版本时,它们现在可以正常工作并且不会出错。
