【问题描述】：

我按照 angular-cli wiki 中的 wiki 了解 Angular 5 中的服务器端渲染。

正确执行了所有步骤。我记得它上周奏效了。我没有对我的系统进行任何更改。

但昨天当我尝试相同的步骤 npm run build:ssr && npm run serve:ssr 时，我收到以下错误：

D:\ssr>npm run webpack:server

> ssr@0.0.0 webpack:server D:\ssr
> webpack --config webpack.server.config.js --progress --colors

我的眼睛在流血！ 1000% ZOOM DOES NOT SUFFICE..请将错误复制粘贴为文本。
也许尝试将 ts-loader 版本设置为 3.5.0？
@David 我相信我在尝试此命令时遇到了该错误：npm run webpack:server
我也相信。你试过我的建议了吗？

【解决方案1】：

此问题是由于 ts-loader 不匹配造成的，如果 webpack 版本是 3.x，请使用 ts-loader 3.5.0，这样应该可以解决问题。
