推荐答案

假设你已经安装了 pydev

Assuming you have installed pydev

在Windows下>首选项>Pydev>解释器>python解释器>转到环境

under Windows > preferences > Pydev > interpreters > python interpreters > go to environment

环境下需要给出pyhton.exe文件的路径，变量名PYSPARK_PYTHON

under environment you need to give path of pyhton.exe file, Variable name as PYSPARK_PYTHON
