一、问题

（在Alpine 上装好spark， 运行 pyspark）

bash-4.4# pyspark
Python 3.6.5 (default, May 30 2019, 09:48:14)
[GCC 6.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
Traceback (most recent call last):
  File "/spark/python/pyspark/shell.py", line 30, in <module>
    import pyspark
  File "/spark/python/pyspark/__init__.py", line 41, in <module>
    from pyspark.context import SparkContext
  File "/spark/python/pyspark/context.py", line 28, in <module>
    from pyspark import accumulators
  File "/spark/python/pyspark/accumulators.py", line 98, in <module>
    from pyspark.serializers import read_int, PickleSerializer
  File "/spark/python/pyspark/serializers.py", line 58, in <module>
    import zlib
ModuleNotFoundError: No module named 'zlib'
>>>

 

二、解决办法

先升级Alpine，再安装pip（安装pip和这错没关系）

bash-4.4# apk add --update py-pip

or

apk update
apk add py-pip

 

fetch http://dl-cdn.alpinelinux.org/alpine/v3.8/main/x86_64/APKINDEX.tar.gz

检查，已经正常运行：

bash-4.4# pyspark
