在我的项目中，我使用 gulp 运行任务，使用 webpack 编译 js 模块，使用 babel loader 来转换 react 和 ES6。现在我想添加继电器转换。我按照以下说明进行操作：https ://facebook.github.io/relay/docs/guides-babel-plugin.html#advanced-usage但它们似乎不正确。

我不得不做一些小的逆向工程，并制作了以下 gulp 任务：

gulp.task('js', () => {
    // Compile babel (react)
    gulp.src(paths.js)
        .pipe(er(webpack({
            module: {
                plugins: [
                    new require('webpack/lib/ProvidePlugin')({
                        React: "React",
                        Relay: 'Relay'
                    })
                ],
                loaders: [
                    {
                        test: /\.jsx?$/,
                        exclude: /(node_modules)/,
                        loader: 'babel',
                        query: {
                            presets: ['es2015', 'stage-0', 'react'],
                            plugins: [require('babel-relay-plugin')(require(paths.db_schema).data)]
                        }
                    }
                ]
            },
            output: {
                filename: paths.js_output
            }
        })))
        .pipe(gulp.dest(paths.dist));
});

现在我得到每个处理的文件这样的错误：

ERROR in (filename)
Module build failed: TypeError: Falsy value found in plugins
    at d:\Node\organize.me\node_modules\babel-core\lib\transformation\file\options\option-manager.js:187:15

    at Object.module.exports (d:\Node\organize.me\node_modules\babel-loader\index.js:88:12)
 @ multi main

我做了更多的逆向工程，我发现插件中的数组只是[ null ]当我用

plugins: [new (require('babel-relay-plugin')(require(paths.db_schema).data))()]

我收到错误

TypeError: Cannot read property 'Plugin' of undefined

那么我怎样才能让 gulp、webpack、babel 和 relay 一起工作呢？谢谢。
