所有的都调试好了，cmd运行pyspark也可以，但在python里的ide运行这一段程序总是报错。

from pyspark import SparkConf, SparkContext

from py4j.java_gateway import JavaGateway

# 初始化Spark
conf = SparkConf().setMaster("local").setAppName("My App")
sc = SparkContext(conf=conf)
print("-----------------2-------------------")
lines = sc.textFile("E:///JinXiejie/spark-2.2.0-bin-hadoop2.7/README.md")
pythonLines = lines.filter(lambda line : "Python" in line)
print("---------------3-----------------")
print
pythonLines.first()

报告错误类型：

C:\Python34\python.exe E:/JinXiejie/PythonCases/PyDemo/Pydemo.py

解决方案：

打开PyCharm，run->edit-Configurations->Environment variables

分别添加PYTHONPATH和SPARK_HOME如下（具体路径为自己电脑spark文件位置）：

问题解决！
