代码

from pyflink.table import StreamTableEnvironment, EnvironmentSettings,
DataTypes
from pyflink.table.udf import udf

# 1. create a TableEnvironment
env_settings =
EnvironmentSettings.new_instance().in_streaming_mode().use_blink_planner().build()

执行执行 py 文件是可以正常运行的

用以下命令提交到 flink 上会报错

flink run -py src/etl/hello_world.py

Hi,

你可以看到报错信息里面有这么一条：
ImportError: No module named pyflink

看起来是你的集群环境使用的python环境没有安装pyflink

Best,
Xingbo

你好，我的本地集群是单点的，直接使用文档里的
bin/start-cluster.sh
命令启动的。

我扫了一遍文档，没找到介绍如何配置集群里的 pylink 相关的信息，可以麻烦你告诉我相关文档在哪里吗

Hi,

你可以参考文档[1]，里面的api
set_python_executable(python_exec)用来设置你的Python环境的，然后你需要确保你这个python环境有安装pyflink。

感谢搞定了，根据你提供的文档，我把命令改为

flink run -py src/etl/hello_world.py -pyexec
/usr/local/opt/python@3.7/bin/python3

指定了 python 执行器就行了

你好、请教下配置pyflink、本地运行报错
[root@hadoop01 ~]# pip list | grep flink
apache-flink (1.12.0)

[root@hadoop01 ~]# python3 -V
Python 3.6.5

flink run -m localhost:8081 -py datastream_tutorial.py -pyexec
/usr/local/python3/bin/python3

 File "datastream_tutorial.py", line 1, in <module>
    from pyflink.common.serialization import SimpleStringEncoder
ModuleNotFoundError: No module named 'pyflink.common.serialization'
，请问下你是如何配置环境变量的吗？谢谢

Hi,

看报错是你的客户端环境所使用的的`python`解释器没有安装pyflink。-pyexec指定的是你udf运行的worker所使用的python环境，但是你在客户端编译作业的时候也需要python环境，那个python环境也需要安装pyflink。

Best,
Xingbo
