我已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)
- 节点模块
- 上市
- 源代码
- 包.json
纱线锁
现在当我运行命令时
indecesion-app> babel src/app.js --out-file=public/scripts/app.js --presets=env,react
它显示错误:
Error: Couldn't find preset "env react" relative to directory "src"
