java - 在 Windows 7 中运行 Play 应用程序时为 "RuntimeException: Problems with NPM resolution"

Question

在我的 Play Framework 应用程序目录中键入命令 sbt clean compile 和 sbt clean run 时，出现以下错误。该项目在 Ubuntu 环境中运行良好。但是，在 Windows 7 环境中它似乎无法运行。我曾尝试在线搜索但没有得到任何帮助。我在 https://github.com/sbt/sbt-less/issues/68 尝试了解决方案，我删除了项目/目标和项目/项目，但这并没有解决它。请帮忙

意外异常

JsEngine npmNodeModules 步骤造成了问题。 Google groups post提供了以下解决方案以在构建期间禁用此步骤:在 build.sbt 中将 JsEngineKeys 设置为 Nil 如下所示解决了问题:

lazy val root = (project in file("."))
  .enablePlugins(PlayScala, BuildInfoPlugin)
  .settings(
    // Disable NPM node modules
    JsEngineKeys.npmNodeModules in Assets := Nil,
    JsEngineKeys.npmNodeModules in TestAssets := Nil
  )
