JsEngine的npmNodeModules步骤产生了问题。Google groups post提供了以下解决方案，以在构建过程中禁用此步骤：如下图所示，在
在Play Framework应用程序的目录中键入命令sbt clean compile和sbt clean run时，会出现以下错误。该项目在Ubuntu环境中运行良好。然而，它在Windows7环境中似乎无法运行。我试过在网上搜索，但没有得到任何帮助。我在https://github.com/sbt/sbt-less/issues/68，其中我删除了项目/目标&项目/项目，但这并不能解决问题。请帮助

build.sbt中将JsEngineKeys设置为Nil解决了问题：
lazy val root = (project in file("."))
.enablePlugins(PlayScala, BuildInfoPlugin)
.settings(
// Disable NPM node modules
JsEngineKeys.npmNodeModules in Assets := Nil,
JsEngineKeys.npmNodeModules in TestAssets := Nil
)
