不能用Webpack构建角度4的例子?

时间:2021-11-19 20:54:54

I recently installed Angular 4 (RC2) and copied the files from the simple Quickstart example. But when I try to build the project with Webpack, I get errors stating that Rxjs can't be resolved:

我最近安装了角4 (RC2),并从简单的Quickstart示例中复制了这些文件。但是,当我尝试使用Webpack构建项目时,我遇到了错误,说明Rxjs无法解决:

I've installed Rxjs 5.0.1, which I think is the version that Angular is expecting. I can't think of anything else to do.

我已经安装了Rxjs 5.0.1,我认为这是angle期待的版本。我想不出别的办法了。

new ContextReplacementPlugin( /angular(\\|\/)core(\\|\/)@angular/, path.resolve(__dirname, '../src') ) Works for me for webpack in webpack.common.js

新ContextReplacementPlugin(/角(\ \ | \ /)核心(\ \ | \ /)@angular /路径。resolve(__dirname, '. /src')对我在webpack.common.js中的webpack适用

work with no problems under this configuration:

在此配置下工作没有问题:

new webpack.ContextReplacementPlugin(
  /angular(\\|\/)core(\\|\/)@angular/,/angular(\\|\/)core(\\|\/)(esm(\\|\/)src|src)(\\|\/)linker/,
  helpers.root('../src'), 
  {} 
),

make sure on helpers.root have two dots, not one. ('../src')

确保在帮手。根有两个点,不是一个。(“. . / src”)
