Angular项目一台机器npm install正常，另一台遇依赖冲突错误

我开发一个Angular项目已有数月，在A机器上运行完全正常（仅偶尔因拼写失误出错）。下月将外出，想在笔记本上运行该项目，已安装好Node、Angular等环境。从Git仓库拉取源码后执行npm i安装node_modules，却出现ERESOLVE依赖冲突错误，涉及@angular/cdk@"^12.1.0"。错误提示需修复上游依赖冲突，或使用--force/--legacy-peer-deps重试。

以下是项目的package.json：

已尝试以下方法但均无效：

• 搜索相关解决方案
• 降级/升级Node和Angular CLI
• 使用npm i --force和npm i --legacy-peer-deps（仍报错）
• 更新错误中提及的单个包
• 查阅Stack Overflow相关问题（未找到有效方案）

解决方案 #

1. 统一Angular CDK与核心框架版本

项目中Angular核心包（如@angular/core）是14.2.12版本，但@angular/cdk停留在12.1.0，版本差距过大导致依赖冲突。将@angular/cdk和@angular/google-maps升级到与Angular核心一致的14.x版本：

"@angular/cdk": "^14.2.12",
"@angular/google-maps": "^14.2.12"

2. 清理缓存并重新安装

执行以下命令彻底清理缓存和旧依赖：

rm -rf node_modules package-lock.json
npm cache clean --force
npm install

3. 检查其他依赖的版本兼容性

• ngx-monaco-editor当前是12.0.0，建议升级到适配Angular 14的版本（如^14.0.0）
• 确认@nebular/*包（10.0.0）是否兼容Angular 14，若存在兼容性问题，可考虑升级Nebular到对应版本或回退Angular到12.x（前者更利于长期维护）

4. 锁定Node版本

确保笔记本上的Node版本与A机器一致（通过node -v查看），不一致的话用nvm等工具切换到相同版本，避免因Node版本差异导致的依赖解析问题。
