在 Python 3.8 上导入 pyspark 时出现“TypeError: an integer is required (got type bytes)”

Question

1. 创建 conda 环境：

conda create -y -n py38 python=3.8
conda activate py38

2. 从 Pip 安装 Spark：

pip install pyspark
# Successfully installed py4j-0.10.7 pyspark-2.4.5

3. 尝试导入pyspark：

python -c "import pyspark"

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/Users/dmitrii_deriabin/anaconda3/envs/py38/lib/python3.8/site-packages/pyspark/__init__.py", line 51, in <module>

    _cell_set_template_code = _make_cell_set_template_code()

TypeError: an integer is required (got type bytes)

似乎 Pyspark 带有预打包版本的cloudpickle包，该版本在 Python 3.8 上存在一些问题，现在已在 pip 版本上解决（至少从 1.3.0 版开始），但是 Pyspark 版本仍然存在问题。有没有人遇到同样的问题/有没有运气解决这个问题？

Answer 1

你必须将你的 python 版本从 3.8 降级到 3.7，因为 pyspark 不支持这个版本的 python。
