Angular升级后ng serve报错：工作目录非绝对路径

问题描述 #

将@angular/cli和@angular/core升级至17.3.7版本后，删除node_modules及package-lock.json，执行npm install后运行ng serve，出现错误：

The working directory "C:\Users\srapolu\gen-ai-latest\gen-ai" is not an absolute path

已尝试重装Angular CLI及重新安装依赖，问题未解决。

解决方案 #

1. 切换到CMD执行命令 #

Windows PowerShell可能存在路径解析问题，打开命令提示符（CMD），执行以下步骤：

• 切换到项目根目录：cd C:\Users\srapolu\gen-ai-latest\gen-ai
• 重新运行：ng serve

2. 统一Angular CLI版本 #

确保全局与本地CLI版本一致：

• 查看全局版本：ng --version
• 查看本地版本：npx ng --version
• 若版本不一致，卸载全局CLI：npm uninstall -g @angular/cli
• 重新安装对应版本：npm install -g @angular/cli@17.3.7

3. 移除esbuild覆盖配置 #

package.json中的overrides配置替换esbuild为wasm版本，可能导致路径解析异常：

• 删除package.json中的以下内容：

"overrides": {
  "esbuild": "npm:esbuild-wasm@latest"
}

• 执行npm install后重新运行ng serve

4. 清理缓存并重置配置 #

• 清理npm缓存：npm cache clean --force
• 清理Angular CLI缓存：ng cache clean
• （可选）重置angular.json配置：先备份原文件，再执行ng update @angular/cli@17.3.7 --force
