每个项目下都有一个package.json文件，里面包含了vue的版本。比如下面是我用vite创建的一个vue项目对应的package.json文件内容：yarncreateviteloqnyn--templatevue:{"name":"loqnyn","private":true,"version":"0.0.0","type":"module","scripts":{"dev":"vite","build":"vitebuild","preview":"vitepreview"},"dependencies":{"vue":"^3.2.45"},"devDependencies":{"@vitejs/plugin-vue":"^4.0.0","vite":"^4.0.0"}}你可以看到vue的版本是写在dependencies下的。3package.json中的“^”是什么意思？在package.json中可以看到：~、^
