找到原因了，项目在初始化时，vue的环境版本被提升到 3.1.3 。在项目根目录使用 vue info 可以看到 vue: ^3.0.0 => 3.1.3 

这个时候需要先 rm -rf ./node_modules 删除已经创建出来的目录，然后 vi package.json 修改 "vue": "^3.0.0" ，改成 "vue": "3.0.11" ，最关键的是要把前面的符号删掉。

之后再执行 npm i ，项目就可以跑起来了。

  是按照课程一样的：
  ? Please pick a preset: Manually select features
  ? Check the features needed for your project: Choose Vue version, Babel, Router,
   Vuex, CSS Pre-processors, Linter
  ? Choose a version of Vue.js that you want to start the project with 3.x (Previe
  w)
  ? Use history mode for router? (Requires proper server setup for index fallback
  in production) No
  ? Pick a CSS pre-processor (PostCSS, Autoprefixer and CSS Modules are supported
  by default): Sass/SCSS (with dart-sass)
  ? Pick a linter / formatter config: Standard
  ? Pick additional lint features: Lint on save
  ? Where do you prefer placing config for Babel, ESLint, etc.? In dedicated confi
  g files
  ? Save this as a preset for future projects? No
