我正在将我当前的项目版本更新为Angular 4.我收到的错误就像Build：找不到tsc文件中’mocha’的类型定义文件
我使用以下步骤更新了项目.
> npm install @ angular / common @ latest @ angular / compiler @ latest @ angular / compiler-cli @ latest @ angular / core @ latest @ angular / forms @ latest @ angular / http @ latest @ angular / platform-browser @ latest @ angular / platform-browser-dynamic @ latest @ angular / platform-server @ latest @ angular / router @ latest @ angular / animations @ latest typescript @ latest –save
>将stypescript版本更新为2.3.1
我正在使用Visual Studio 2015 Update 3.
这是我的package.json文件

解决方法
我认为你所看到的是Visual Studio正在尝试在编译时为你构建你的打字稿,但是不知道你的npm脚本中的单独构建过程.如果您有另一个编译过程,我认为您可以安全地禁用此功能,如本文所述：

重要的步骤是：
添加节点
<TypeScriptCompileBlocked>true</TypeScriptCompileBlocked>
到第一个
<PropertyGroup>
.csproj文件中的元素.
