提交火花期间 pyspark 出现 Windows Spark_Home 错误

Question

在简单的 python 脚本上运行 spark-submit 以导入 sparksession 时出现以下错误。我将Spark_Home 用户变量设置为'C:\Spark\spark-3.1.2-bin-hadoop3.2'；用户变量中的 ENV 路径设置为 C:\Spark\spark-3.1.2-bin-hadoop3.2\bin； HADOOP_HOME 路径设置为带有 WINUTILS 的文件夹。

在这里做了所有事情：https://phoenixnap.com/kb/install-spark-on-windows-10

完整代码如下。

尊敬的我尝试PATH issue: Could not find valid SPARK_HOME while searching这不起作用，我在Windows上。这是与工作相关的，我是 stackoverflow 和 Spark 的新手。谢谢！！

尝试使用findspark。

import findspark
findspark.find()

from pyspark import SparkContext, SparkConf
from pyspark.sql import SparkSession

spark = SparkSession.builder \
    .master("local") \
    .appName("Spark") \
    .getOrCreate()
