我有一个使用babel-preset-react-app. 我想通过运行带有@babel/node. 不幸的是，我收到以下错误：

/home/trpgb21/develop/ts-demo-new/src/index.tsx:1
import * as React from "react";
       ^

SyntaxError: Unexpected token *

为什么 babel 不使用预设转换代码？？？

这是我的package.jsonbabel 块供参考：

  "babel": {
    "presets": [
      "react-app"
    ]
  },

通过"debug": true为@babel/preset-env我解决这个问题，以防其他人遇到带有 babel 的递归 program.body 循环：

{
    "presets": [
        [
            "@babel/preset-env",
            {
                "loose": true,
                "modules": false,
                "debug": true
            }
        ]
    ],
    "env": {
        "commonjs": {
            "presets": [
                [
                    "@babel/preset-env",
                    {
                        "loose": true,
                        "modules": "commonjs"
                    }
                ]
            ]
        },
        "test": {
            "presets": [
                [
                    "@babel/preset-env",
                    {
                        "loose": true
                    }
                ]
            ]
        }
    }
}
