Laravel 7：无法在全新安装时运行 Dev

Question

我目前正在执行这些终端命令：

1. composer create-project --prefer-dist laravel/laravel:^7.0
2. 作曲家需要 laravel/ui:^2.4
3. php artisan ui bootstrap --auth
4. npm install && npm run dev

这将返回以下错误

sh: mix: command not found
npm ERR! code ELIFECYCLE
npm ERR! syscall spawn
npm ERR! file sh
npm ERR! errno ENOENT
npm ERR! @ development: `mix`
npm ERR! spawn ENOENT
npm ERR! 
npm ERR! Failed at the @ development script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

我无法修复或识别问题，我已执行以下操作以尝试修复问题：

1. npm 重建 node-sass
2. npm install --global cross-env
3. npm 缓存清理 --force
4. npm install laravel-mix --save-dev

无济于事，我在运行此命令之前也收到警告：

npm WARN lifecycle The node binary used for scripts is /home/jonahmar/nodevenv/onyx.website.io/12/bin/node but npm is using /opt/alt/alt-nodejs12/root/usr/bin/node itself. Use the `--scripts-prepend-node-path` option to include the path for the node binary npm was executed with.
