Ubuntu22.04 pyflink的下载安装

官网提供的下载方式：

python -m pip install apache-flink==1.14.4

太慢，报错：时间超时

自己指定源下载：

python -m pip install apache-flink==1.14.4 -i https://mirror.baidu.com/pypi/simple

报错：

This error originates from a subprocess, and is likely not a problem with pip.

经过查阅资料发现自己的Python版本太高了。

python降版本

先安装python3.8:

sudo GNUTLS_CPUID_OVERRIDE=0x1 apt-get install python3.8

如图表示安装成功

安装pyflink

创建软连接：

# 在/usr/bin目录下
rm -rf /usr/bin/python   # 删掉之前的 
sudo ln -s /usr/bin/python3.8 /usr/bin/python

python -m pip install apache-flink==1.14.4 -i https://mirror.baidu.com/pypi/simple

# 报错：

# 解决：
sudo GNUTLS_CPUID_OVERRIDE=0x1 apt-get install python3.8-distutils
# 重新下载
python -m pip install apache-flink==1.14.4 -i https://mirror.baidu.com/pypi/simple

在测试一下word_count.py,成功运行！！！
