升级到Angular 5后，我的项目无法构建。我正在使用Visual Studio 2017 15.4.3并且正在使用SystemJs。我的打字稿版本是2.4.2。
我收到以下8个错误：
Error Build:',' expected. node_modules\@angular\platform-browser\src\browser\transfer_state.d.ts line 34 oolumn 31

我想出了如何最终修复它。我所做的是从Visual Studio中删除Typescript扩展（从“获取工具和功能”菜单中取消选中TypeScript选项，并从“扩展和更新”中删除它，然后下载并安装“适用于Visual Studio 2017的TypeScript 2.6.1”我曾尝试安装“TypeScript 2.6.1 for Visual Studio 2017”，但是没有用。我的问题只能通过首先从Visual Studio 2017中删除Typescript来解决，然后安装“TypeScript 2.6.1 for Visual Studio 2017“。在尝试任何这个之前，我确实删除了Melchia建议的node_modules目录，但是它本身不起作用，但是可能首先执行此操作是修复的必要部分，尽管我不确定。如果删除打字稿然后安装它不适合你，你可以尝试删除node_modules目录并运行npm install。希望这有助于其他人。

删除node_modules文件夹＆amp;运行 npm install
