所以我得到了一个需要全局安装的包，它需要用户定义的反应组件并呈现它们。我使用babel-register并定义：

require('babel-register')({
    presets: [
        'es2015',
        'stage-0',
        'react',
    ],
});

我的package.json文件如下所示：

"dependencies": {
    "babel-preset-es2015": "^6.24.1",
    "babel-preset-react": "^6.24.1",
    "babel-preset-stage-0": "^6.24.1",
    "babel-register": "^6.24.1",
    "babel-runtime": "^6.23.0",
    "chokidar": "^1.7.0",
    "del": "^2.2.2",
    "marked": "^0.3.6",
    "react": "^15.5.4",
    "react-dom": "^15.5.4",
    "window-size": "^1.0.0",
    "yamljs": "^0.2.10"
},

现在因为那些用户定义的 react 组件有时存在于没有.babelrc安装或任何包的地方，我真的很想使用已经全局安装的包依赖项。当您在全局安装我的包时，我试图避免安装这些依赖项。虽然不确定如何。

我检查了 node_module 文件夹并在那里安装了所有依赖项：

220 directories, 0 files

我得到这个错误：Couldn't find preset "es2015" relative to directory。

在本地安装可以，但我不能使用 bin 绑定和我想添加的其他一些功能。

我试图玩弄ignoreoronly选项，但没有成功。

所以我猜：

问题

如何导入反应组件并从远离我自己的文件夹的文件夹中对它们进行 babelfy，该文件node_modules夹可能没有安装任何依赖项而不会出现错误？

更新

事实证明，您可以将绝对路径传递给babel-register调用：

require('babel-register')({
    presets: [
        Path.normalize(`${ __dirname }/../node_modules/babel-preset-es2015`),
        Path.normalize(`${ __dirname }/../node_modules/babel-preset-stage-0`),
        Path.normalize(`${ __dirname }/../node_modules/babel-preset-react`),
    ]
});

这似乎可行，但现在该应用程序抱怨无法找到react:Error: Cannot find module 'react'即使它在依赖项中。

更新#2

所以找不到react的错误与明显导入react的组件有关。我想知道是否可以将导入语句重定向到我的全局文件夹？是的，你可以使用这个漂亮的插件：https ://github.com/Velenir/babel-plugin-import-redirect :)

所以答案原来是我babel-register调用中的绝对路径。这解决了最初的问题。:) 希望它可以帮助路过的人。

require('babel-register')({
    presets: [
        Path.normalize(`${ __dirname }/../node_modules/babel-preset-es2015`),
        Path.normalize(`${ __dirname }/../node_modules/babel-preset-stage-0`),
        Path.normalize(`${ __dirname }/../node_modules/babel-preset-react`),
    ]
});
