我很抱歉问一个我以前在这里见过的问题，但我所得到的答案似乎都不能解决这个问题。我遵循了在本地机器上运行pyspark的安装文档。完成后，我将尝试使用

# Start pyspark via provided command

import pyspark

# Below code is Spark 2+

spark = pyspark.sql.SparkSession.builder.appName('test').getOrCreate()

spark.range(10).collect()

但我不断得到以下错误：

/Users/usr123/opt/anaconda3/lib/python3.7/site-packages/pyspark/bin/spark-class: line 71: /usr/bin/java/bin/java: Not a directory
Traceback (most recent call last):

    raise Exception("Java gateway process exited before sending its port number")
Exception: Java gateway process exited before sending its port number

有没有人找到一个好办法来确保这个问题得到纠正？我有什么明显的遗漏吗？
