node.js - npm npm run watch-poll 发生 homestead 错误

Question

我正在尝试使用 npm 来处理我在 Homestead 正在进行的项目，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 的新手，我不知道该怎么做，而且我在网上也没有发现任何人遇到类似的问题。

npm 版本 = 6.7.0

Node 版本 = v10.15.1

如果你需要的话。

我将不胜感激任何帮助，如果您需要有关我正在运行的内容以及如何设置的更多信息，请告诉我。

正在运行

npm install

给出这个结果

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

好吧，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，而且看起来它有效。

但是我现在收到一个新错误

 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 sudo npm i -g cross-env 看起来已经修复了它。

您缺少模块跨环境。运行:

npm i -g cross-env

全局安装跨环境。
