我是 node 和 react 的新手，我正在尝试使用创建一个 react 应用程序 npx create-react-app 示例在创建应用程序时，npm 正在尝试安装 react-scripts 模块并且失败并出现以下错误

我在谷歌搜索时出错，我找不到解决方案，我已采取措施解决问题

npm 缓存清理
尝试全局安装 react-scripts
删除 npm 配置中的代理并尝试安装

这些都没有效果

Answer 1

我建议升级您的 node.js，然后再次尝试 npm install：

npm cache clean -f
npm install -g n
n stable
npm install

无法通过 npm install 安装 react-scripts
