How do I resolve "AttributeError: 'NoneType' object has no attribute 'origin'" when attempting to run pyspark on macOS

Question

I have installed pyspark on macOS using brew but I'm getting the error when I type pyspark in zsh:

Traceback (most recent call last):
  File "/opt/homebrew/bin/find_spark_home.py", line 86, in <module>
    print(_find_spark_home())
  File "/opt/homebrew/bin/find_spark_home.py", line 52, in _find_spark_home
    module_home = os.path.dirname(find_spec("pyspark").origin)
AttributeError: 'NoneType' object has no attribute 'origin'

I've tried setting the path inside the pyspark script but then got

/opt//homebrew/Cellar/apache-spark/3.3.1/bin/load-spark-env.sh: line 2: /opt/homebrew/Cellar/apache-spark/3.3.1/libexec/bin/load-spark-env.sh: Permission denied
/opt//homebrew/Cellar/apache-spark/3.3.1/bin/load-spark-env.sh: line 2: exec: /opt/homebrew/Cellar/apache-spark/3.3.1/libexec/bin/load-spark-env.sh: cannot execute: Undefined error: 0

How do I resolve this error?

Answer 1

I first had to locate and copy the apache spark directory to usr/local:

sudo cp -r /opt/homebrew/Cellar/apache-spark /usr/local/Cellar/

I found the spark directory with sudo find /opt/ -name find_spark_home.py then I set the environment variables:

SPARK_HOME=/usr/local/Cellar/apache-spark/3.3.1/libexec
export PATH=/usr/local/Cellar/apache-spark/3.3.1/bin:$PATH

after that typing pyspark gives:
