我安装了Spark,但是在将pyspark模块加载到ipython中时遇到了问题。我收到以下错误:
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-2-49d7c4e178f8> in <module>
----> 1 import pyspark
/opt/spark/python/pyspark/__init__.py in <module>

ModuleNotFoundError: No module named 'py4j'
如果可以直接运行 Spark,也许你必须修复环境变量PYTHONPATH
。检查目录中的文件名 $SPARK_HOME/python/lib/
。如果是 Spark 版本 2.4.3,则文件py4j-0.10.7-src.zip
:
export PYTHONPATH=$SPARK_HOME/python:$SPARK_HOME/python/lib/py4j-0.10.7-src.zip:$PYTHONPATH
