Question

我试图使用Babel转换ES6文件 - 但NPM不喜欢命令 babel src --out-dir输出，它是使用我的脚本运行的的package.json。

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，它运行正常。

如果我不必，我想避免在全球范围内安装Babel。

错误（请参阅下面的调试日志） TypeError：src / person.js：预期＆＃39;输入＆＃39;成为一个＆＃39;字符串＆＃39;得到＆＃39;数字＆＃39; 看起来命令 babel src --out-dir输出＆＃34;在您的系统上失败＆＃34;

项目设置

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

的package.json

  "version": "0.0.0",

  "license": "UNLICENSED",

  "devDependencies": {

}

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

我真的不确定这出错的地方，也无法找到错误的帖子。

感谢您的帮助

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。这工作正常，所以我再次尝试了 npm run build 命令，它运行了（我检查过，babel-cli -g也被卸载了）。

如果有人能说清楚出了什么问题，那就太棒了!!!
