解决方案

删除 .parcel-cache 和 dist 文件夹并再次运行命令。 (注意:在 Parcel 1.x 版本中，缓存文件夹仅称为 .cache。)

提案

为此添加清理脚本并在每次构建包裹之前运行它:

 "scripts": {
   "cleanup": "rm -rf .parcel-cache dist",
   "dev": "npm run cleanup && parcel ./index.html",
   ...
 }

您还可以使用 rimraf lib 执行跨平台清理任务。 https://www.npmjs.com/package/rimraf 。所以脚本将如下所示:

 "scripts": {
   "cleanup": "rimraf .parcel-cache dist",
   "dev": "npm run cleanup && parcel ./index.html",
   ...
 }
