Question

我是Jython和PyDev的新手。我需要在Eclipse中运行我的Python代码。 Python代码可在Spyder / Jupyter Notebook中使用。当我以Jython Run / Python Run的身份运行程序时，将弹出错误。我该如何解决这个问题？

这里讨论了类似的问题 How do I fix UnsupportedCharsetException in Eclipse Kepler/Luna with Jython/PyDev? 并添加

-Dpython.console.encoding = UTF-8

运行配置-> VM参数可能是解决方案。

有没有办法在Pydev中运行Python代码？
