File could not be found when importing code snippet in VuePress

Question

According to VuePress's documentation

I would like to import code snippet into the Markdown file, but the documentation is not quite clear how can I work with the file path.

Path

|-package.json
+-src
|    |-readme.md
|    +-snippets
|    |    |-file.js

package.json

{
  "scripts": {
    "dev": "vuepress dev src"
  }
}

src/readme.md

<<< @/snippets/file.js

<<< @/src/snippets/file.js

Output

Not found: d

I have tried many different ways to import code snippet but it's still not working.
