如何将node低版本运行的vue项目 用高版本node 如node16运行？有什么思路？
一个老项目 使用vue开发的，之前一直用node14运行的 领导希望高版本的也能运行，至少是node16.
但当我使用node16，npm install 去报错无法下载依赖，甚至无法运行

回答：
- 删除
package.lock.json。 - 删除
node-sass,改用sass,node-sass对node版本依赖严重。 - 升级部分依赖版本。
尝试上面几个步骤，一般可以解决
回答：
vue 跟 node 版本没什么关系，你的问题出在项目依赖里限制了 node 版本，所以新版本 node 就不工作。
结局方案很多，我的建议是：
- 升级依赖，尽量都升级到最新版本。一般建议从 webpack 等基础架构开始升。
- 如果不行的话，退而求其次，删掉 lock 文件重新装，有时候也能解决
- 然后升级那些卡住你的依赖，保留没有提示的依赖版本，即可
