试图在ubuntu 18.04上运行此命令

npm install -g pngquant-bin

但我得到了这个错误,

我正在尝试在 Ubuntu 18.04 上部署我的工作 Windows 10 Spring-Boot/React 应用程序，但尽管多次尝试修复，但仍然收到“react-scripts: Permission denied”错误。希望你们中的一位反应专家可以发现我做错了什么。

我已经在我的服务器（Centos）上完成了我的 ODOO v9 安装。一切都已成功安装。登录页面也可以正常工作，但登录后出现以下错误的页面

/usr/bin/env : node : Permission Denied

我试图更改权限，但我的问题没有解决。有谁知道这是什么错误？
