Node.js Keystone+；反应：'；导入&x27；和'；出口'；只能与'；sourceType:module'；

更新项目依赖项后，我开始面临错误。Browserify在解析用ES6编写的JS代码时遇到问题。Browserify似乎期待ES5

我不明白，为什么

sourceType:module

似乎是这里的问题

资料来源：

var babelify = require('babelify');
var browserify = require('browserify-middleware');
var keystone = require('keystone');   
var importRoutes = keystone.importer(__dirname);

// Setup Route Bindings
exports = module.exports = function(app) {

    app.use('/js', browserify('./client/scripts', {
        transform: [babelify.configure({
            extensions: ['es6'],
            plugins: ['object-assign']
        })]
    }));

};

在上述代码中省略

babelify

时，也会发生同样的情况：

var browserify = require('browserify-middleware');
var keystone = require('keystone');   
var importRoutes = keystone.importer(__dirname);

// Setup Route Bindings
exports = module.exports = function(app) {

    app.use('/js', browserify('./client/scripts'));

};

问题在于

扩展名：['es6']

中的值不正确，需要的是将JS文件的实际扩展名

扩展名：['.JS']

工作守则：

var babelify = require('babelify');
var browserify = require('browserify-middleware');
var keystone = require('keystone');   
var importRoutes = keystone.importer(__dirname);

// Setup Route Bindings
exports = module.exports = function(app) {

    app.use('/js', browserify('./client/scripts', {
        transform: [babelify.configure({
            extensions: ['.js'],
            plugins: ['object-assign']
        })]
    }));

};
