我们正在使用TFS 2015并尝试使用NPM和JSPM构建网站项目。 在开发过程中，我们一直在运行＆＃34; npm install＆＃34;和＆＃34; jspm安装＆＃34;在添加新包等时从命令行，这已经工作正常。 我现在正试图在TFS上建立项目。 我尝试将以下内容添加到.csproj中：
<Target Name="AfterBuild">
<Exec Command="attrib -r .dependencies.json" WorkingDirectory=".\jspm_packages" />
<Exec Command="attrib -r jspm.config.js" WorkingDirectory="." />
<Exec Command="attrib -r package.json" WorkingDirectory="." />
<Exec Command=".bin\npm install" WorkingDirectory="." />
<Exec Command=".bin\jspm install -y" WorkingDirectory="." />
<Exec Command=".bin\node build.js --minify --sourceMaps" Condition="'$(Configuration)|$(Platform)' == 'Release|AnyCPU'" WorkingDirectory="." />
</Target>
并且，作为单独尝试使其工作，我尝试创建.cmd文件（tfsbuild.cmd）：
attrib -r "jspm_packages\.dependencies.json"
attrib -r "jspm.config.js"
attrib -r "package.json"
call .bin\npm install > _npm.log
call .bin\jspm install -y > _jspm.log
call .bin\node build.js --minify --sourceMaps > _nodebuild.log
并从.csproj
调用它<Exec Command="tfsbuild.cmd" Condition="'$(Configuration)|$(Platform)' == 'Release|AnyCPU'" WorkingDirectory="." />
我尝试的所有构建都失败了，说jspm install命令退出代码1.请注意，我将命令的输出提供给.log文件以帮助理解问题。 如果我直接从.csproj文件在TFS构建机器上运行的文件夹中运行tfsbuild.cmd，那么一切正常，并且jspm.log文件输出预期的响应:(截断）

但是，从构建过程调用tfsbuild.cmd时，输出到jspm.log的情况非常不同，并且将代码1返回给msbuild，因此构建失败。 （整个文件）

我很困惑，为什么从msbuild运行时命令的行为会有所不同。任何帮助将非常感激。谢谢。
