org.scalajs.jsenv.ExternalJSEnv$NonZeroExitException：PhantomJS2 已退出，代码为 2
org.scalajs.jsenv.ExternalJSEnv$NonZeroExitException: PhantomJS2 exited with code 2
我使用 scalatest 作为我的测试框架，这是我的测试代码：
import org.scalatest.FunSuite
class SampleTest extends FunSuite{
test("hello") {
println(s"sdfsf")
}
}
build.sbt 设置
val scalatestJS = libraryDependencies += "org.scalatest" %%% "scalatest" % Version.scalatest % Test
val scalatestJSSettings = Seq(
scalatestJS,
scalaJSStage in Global := FastOptStage,
// scalaJSStage in Global := FullOptStage,
// jsDependencies += RuntimeDOM,
// jsDependencies += ProvidedJS / "test-bundle.js" % Test,
jsEnv in Test := new PhantomJS2Env(scalaJSPhantomJSClassLoader.value, addArgs = Seq("--web-security=no"))
// jsEnv in Test := new NodeJSEnv()
)

注意：这曾经很好用，但现在不行了:s
编辑：
Scala 测试：3.0.0-M15
ScalaJS：0.6.9
斯卡拉：2.11.8
幻影JS：2.0.0
在我的代码中，我有一个 class 扩展了 js class
@ScalaJSDefined
class MyLab(container : dom.Node) extends JSLab(container) {... }
尽管我没有在我的测试中使用这个 class，看起来为这一行生成的源代码是如何在全球范围内寻找 JSLab 的！这会导致 phantomjs 崩溃。有趣的是，测试在 Rhino 上执行得很好 :s。无论如何，我将 JSLab 添加为测试依赖项并且错误消失了。
我不知道该怪谁，无论是愚蠢的开发人员（我）在解决问题时走向了不同的方向，还是 scala.js 对 phantomjs 崩溃的原因没有帮助：s
