在Pycharm上使用python执行spark程序时遇到错误

Question

我在PyCharm上编写了一个名为Wordcount.py的python文件。 这是Wordounct.py

import sys,os from pyspark import SparkContext 
sc = SparkContext() 
myrdd = sc.textFile("passwd") 
myrdd.count() 

当我运行它的内容，我中遇到上控制台

显示一个错误以下是错误信息

/usr/local/bin/python3 /home/plters/PycharmProjects/Spark21/Wordcount.py 
Traceback (most recent call last): 
    File "/home/plters/PycharmProjects/Spark21/Wordcount.py", line 2, in <module> 
    from pyspark import SparkContext 
    File "/opt/spark2/python/pyspark/__init__.py", line 44, in <module> 
    from pyspark.context import SparkContext 
    File "/opt/spark2/python/pyspark/context.py", line 29, in <module> 
    from py4j.protocol import Py4JError 
ImportError: No module named 'py4j 

我应该怎么办？

Answer 1

看起来py4j模块丢失，从终端只需安装

pip install py4j
