node.js - Node js 应用程序的 Azure 部署失败：npm ERR！代码 EPERM

问题描述

我正在尝试在 Azure 应用服务上部署节点 js 应用程序。应用程序文件和 node_modules 文件夹按预期创建，但应用程序无法启动并出现以下错误

它是基于 Linux 的应用服务。启动命令 - npm install && npm start

节点版本 12. NPM - 6.14

该应用程序在第一次部署时工作，但在所有进一步的部署中都失败了

我被困在这两天了。提前致谢

解决方案

Node js 应用程序的 Azure 部署失败：npm ERR！代码 EPERM

您可以尝试通过命令行清理 npm 缓存：

npm cache clean --force

如果它不适合您，请手动删除缓存文件。为此，请转到默认 NPM 缓存文件夹并删除其内容：

默认值：~/.npm在linux上，或%AppData%/npm-cache在 Window 上

然后您可以尝试安装并启动您的应用程序。

笔记：

避免使用sudo npm install -g，因为您可能会弄乱 npm 权限。而是将权限更改为 npm 的默认目录，或者将 npm 的默认目录更改为另一个目录。更多详细信息：https ://docs.npmjs.com/getting-started/fixing-npm-permissions
