Question

我为angular2 rc.5开发提供了以下webpack设置，但失败并出现以下错误

url_resolver.js:238Uncaught TypeError: uri.match is not a function

webpack看起来像

var sliceArgs = Function.prototype.call.bind(Array.prototype.slice);
var toString  = Function.prototype.call.bind(Object.prototype.toString);
//const helpers = require('./helpers');
var webpack = require("webpack"),
              ExtractTextPlugin = require('extract-text-webpack-plugin'),
              //helpers = require('./helpers'),
              path = require('path');

var CommonsChunkPlugin = webpack.optimize.CommonsChunkPlugin;

module.exports = {
    entry: {
        'vendor': [

}

是否有针对此错误的修复程序？

Answer 1

我在迁移到webpack后遇到了类似的问题，这是由在为SystemJS设计的组件中使用moduleId: module.id引起的。

如果您的代码中出现moduleId，请删除它们。

在github上查看此问题：https://github.com/angular/angular/issues/10626

Answer 2

我有同样的问题，但由于问题来自angular2-material 2.0.0-alpha.7-4，我使用了基于以下的临时修复：https://github.com/angular/material2/issues/974#issuecomment-242936198

npm i --save string-replace-loader

webpack.conf

...
preLoaders: [
  {
    test: /.js$/,
    loader: 'string-replace-loader',
    query: {
      search: 'moduleId: module.id,',
      replace: '',
      flags: 'g'
    }
  },
]
...
