在哪里可以看到节点和npm Laravel 7需要什么版本？
文档中没有任何内容：www.example.comhttps://laravel.com/docs/7.x/mix#installation
我安装了这些版本，但在运行"npm run development"时出现错误

npm -v
6.14.5

node -v
v6.17.0

已经阅读了旧版本的npm和节点，可能导致该原因。还阅读了cross-env的位置已更改，但不确定这意味着什么或在哪里更改：/
错误：

ec2-user:~/environment (master) $ npm run development

> @ development /home/ec2-user/environment
> cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

尝试删除node_modules文件夹，然后运行"npm安装"，但仍然得到错误。认为我已经运行最新版本的npm和节点。
