reactjs - react : Couldn't find preset "env react" relative to directory "src"

Question

我使用以下命令将预设 react 和 env 添加到我的 react 项目中:

yarn 全局添加 babel-preset-react@6.24.1 babel-preset-env@1.5.2

My package.json file has updated the presets and looks like the following:
  {
  "name": "indecesion-app",
  "version": "1.0.0",
  "main": "index.js",
  "author": "ak",
  "license": "MIT",
  "dependencies": {
    "babel-preset-env": "1.5.2",
    "babel-preset-react": "6.24.1"
  }
}

甚至我的 node_modules 文件夹也更新了预设。

文件夹结构如下所示:

indecesion-app(应用程序的文件夹名称)

node_modules

公众号

源

package.json

yarn 锁

现在当我运行命令

indecesion-app> babel src/app.js --out-file=public/scripts/app.js --presets=env,react

它显示错误:
