npm npm run watch-poll 家园错误

Question

我正在尝试将 npm 用于我正在 Homestead 从事的项目，但是我遇到了一些错误。 我跑了

npm run watch-poll

但我收到此错误

vagrant@homestead:~/code/testlaravel$ npm run watch-poll

> @ watch-poll /home/vagrant/code/testlaravel
> npm run watch -- --watch-poll


> @ watch /home/vagrant/code/testlaravel
> npm run development -- --watch "--watch-poll"


> @ development /home/vagrant/code/testlaravel
> cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress 
--hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js "--watch" "--watch-poll"

我是 npm 新手，我不知道该怎么做，也没有在网上找到有类似问题的人。

npm 版本 = 6.7.0

节点版本 = v10.15.1

如果你需要的话。

如果您需要有关我正在运行的内容以及设置方式的更多信息，我将不胜感激。

运行

npm install

给出这个结果

vagrant@homestead:~/code/testlaravel$ npm install

好的，我跑了

sudo npm i -g cross-env

因为我在没有 sudo 位的情况下遇到了权限错误，而且它看起来有效。

但是我现在遇到了一个新错误

 ERROR  Failed to compile with 2 errors                                                                                                                                                  3:18:10 PM

 error  in ./resources/assets/sass/app.scss

 error  in ./resources/assets/sass/app.scss

我猜这是我的代码/框架的问题（我正在使用 laravel）但是是的 sudo npm i -g cross-env 看起来它已修复它。

您缺少跨环境模块。运行：

npm i -g cross-env

全局安装跨环境。
