我提前为我的近似英语道歉:)
这里有一个小回顾：我们有一个 Rails 4 项目，最近我们用 React_on_rails gem 添加了一些 React 组件，所以我们需要实现 Webpack 作为 Asset Pipeline 的朋友（是的，我知道，Rails 5 做得更好)
所以问题是，当我尝试在登台上进行部署时，以及在尝试对其进行部署时yarn run build:production：
$ NODE_ENV=production webpack -p --config webpack.config.js
/home/unisc/apps/staging/releases/20170831104131/client/node_modules/react-on-rails/webpackConfigLoader.js:14
const { join, resolve } = require('path');
^

这是我的 package.json ：

和我的 webpack.config.js ：
// For inspiration on your webpack configuration, see:

const webpack = require('webpack');

const ManifestPlugin = require('webpack-manifest-plugin');
const webpackConfigLoader = require('react-on-rails/webpackConfigLoader');
const configPath = resolve('..', 'config');
const { devBuild, manifest, webpackOutputPath, webpackPublicOutputDir } =
webpackConfigLoader(configPath);
const config = {

entry: {

output: {

module: {

test: require.resolve('react'),
use: {

sham: 'es5-shim/es5-sham',
},
},
},
{
test: /\.jsx?$/,
use: 'babel-loader',
exclude: /node_modules/,
},
],
},
};
module.exports = config;
if (devBuild) {
console.log('Webpack dev build for Rails'); // eslint-disable-line no-console
module.exports.devtool = 'eval-source-map';
} else {
console.log('Webpack production build for Rails'); // eslint-disable-line no-console
}
我试图找到同样的问题但没有成功......
此命令适用于我的机器，两者（我的机器和登台）都具有相同版本的 webpack，并且无论如何它们都使用 node_modules 中的那个。
感谢阅读，祝您有美好的一天；）
我试过的：
- npm 升级，纱线升级，删除 node_modules 并重试
- 将整个配置文件转换为 es5，但它碰到了依赖项中的另一个花括号
- 试图移动，删除 .babelrc 文件
我实际上在尝试什么：
- 看起来 es6 转译过得不好
