Question

我正在将当前的项目版本更新为Angular 4.我收到的错误如Build:Cannot Find type definition file for 'mocha' in tsc file

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

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，但是从你的npm脚本中不知道你的单独构建过程。如果你有另一个编译过程，我认为你可以放心地禁用这个功能，如本文所述：http://rostacik.net/2015/08/14/how-to-disable-building-of-typescript-files-in-visual-studio-2015/

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。

构建：更新为角度4后，无法在tsc文件中找到“mocha”的类型定义文件
