我正在尝试使用 Babel 转换 ES6 文件 - 但 NPM 不喜欢使用我的 package.json 中的脚本运行的命令babel src --out-dir 输出。

但是，当我全局安装 Babel 并在不使用脚本的情况下运行相同的命令时，它工作得很好。

如果不需要的话，我想避免全局安装 Babel。

错误（请参阅下面的调试日志） TypeError: src/person.js: Expected 'input' to be a 'string', got 'number' 看起来像命令babel src --out-dir output "fails on your system"

项目设置

-> root
   -> node_modules
   -> output
   -> src
      - person.js
   - .babelrc
   - package.json

包.json

{
  "name": "Test",
  "version": "0.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "build": "babel src --out-dir output"
  },
  "author": "Me",
  "license": "UNLICENSED",

  "devDependencies": {
    "babel-cli": "~6.11.4",
    "babel-preset-es2015": "^6.9.0"
  }

}

人.js

class Person {
    constructor(name) {
        this.name = name;
    }
}

.babelrc

{
  "presets": ["es2015"]
}

我真的不确定这是哪里出错了，也找不到关于错误的任何帖子。

问题解决了（侥幸）！

我仍然不确定问题是什么，但是我已经将 webpack 添加到我的项目中，并添加了另一个脚本来运行webpack命令。这工作得很好，所以我再次尝试了npm run build命令并且它工作了（我检查并且 babel-cli -g 也被卸载了）。

如果有人能解释出了什么问题，那就太好了！！！

谢谢
