Angular 5 TypeError: AngularCompilerPlugin不是一个构造函数。

我的环境是Angular 5和aspnetcore 2.0。

我将我的包更新到了Angular 5，并在webpack.config.js中将AotPlugin替换为AngularCompilerPlugin。但在发布项目时，我遇到了以下错误：

 TypeError: AngularCompilerPlugin is not a constructor

因此，我撤销了这些更改并在webpack.config.js中恢复了AotPlugin，现在我的发布成功了。

实际上，对于angular 5，使用的是AngularCompilerPlugin而不是AotPlugin。所以我的问题是，我错过了什么？我在这里做错了什么？

webpack.config.js

const path = require('path');
const webpack = require('webpack');
const merge = require('webpack-merge');
const AngularCompilerPlugin = require('@ngtools/webpack').AngularCompilerPlugin ;

module.exports = (env) => {

我检查了一下，在发布时它没有采用更新的版本。这是什么原因？

没有看到您的webpack.config很难确定问题所在。

以下是我的首选方式：

const AotPlugin = require('@ngtools/webpack').AngularCompilerPlugin;

plugins: [
        new AotPlugin({
            tsConfigPath: './tsconfig.json',
            entryModule: path.join(__dirname, 'src/app/app.module#AppModule')
        })
]
没什么可展示的，我只是在 webpack.config 中将所有的 AotPlugin 替换为 AngularCompilerPlugin，其余都保持不变。 - k11k2
很难猜测原文是什么样的 :) - pixelbits
我尝试了上面的方法，但仍然没有运气。抛出相同的错误。 - k11k2
@angular/compiler-cli的版本是多少？ - pixelbits
刚刚我发现了一个奇怪的问题：我的npm文件夹中的依赖项都回退到了4.2.5版本。这是怎么发生的？最初，我更新了所有的包并运行了应用程序，检查它们的版本为5.0.5。后来，在webpack更改之后，又回退到了旧版本。 - k11k2

我已经手动将版本号从4.2.x更改为5.0.x在package.json中，因此它没有反映在package-lock.json中。在发布时，考虑到package-lock.json，我遇到了上述错误，因为angular 4.2不支持AngularCompilerPlugin。npm > 5版本允许我同时更新package.json和package-lock.json。
