源代码编译时没有错误
却在程序第31行出错
第31行用到了Graph.fromEdge方法
请问是什么原因？

[人生偌只如初见]

两个环境使用的版本是不是一样的？

[人生偌只如初见]

最好把你写的代码也贴出来

[skyWalker_ONLY]

你看看源代码中有这个方法吗

[sinat_22224149]

我用到的是spark的GraphX库，是包含fromEdges方法的 而且我使用Eclipse编译器写的程序，编译通过没有错误 今天我试了一下，在spark的spark-shell命令行模式中，一步步运行，到31行时却没有错误 将程序打成jar包，运行到31行却出错 不知是什么原因？

我也遇到了类似的问题，楼主解决了吗

[dolphin_sky]

我也遇到类似的问题，猜测应该是打包的版本 与 运行时版本不一致导致的。

[sinat_24241627]

遇到同样的问题，请教楼上是怎样解决的？

[shengruxiahua2571]

调整一下所依赖的jar包的顺序试试，spark的在上，scala自带的在下，我也遇到了这个问题，调整后解决了
