今回でたエラー

(node:1050) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)
[error] Invalid configuration for file "ご自身のプロジェクトパス":
[error] Unexpected token 'export'

解決策

package.jsonに下記を追記するだけ

"type": "module",

追記後のpacage.jsonは下記になります。

  "name": "hogehoge",
  "version": "0.1.0",
  "private": true,
  "type": "module",
