airflow使用过程中的问题记录

大家好，欢迎来到IT知识分享网。

使用python校验dag脚本报错在这里插入代码片

python3 test.py

提示缺少模块或者直接报错的
重新安装python3，编译的时候看有没有依赖的模块未安装

类似下面这种

Python build finished, but the necessary bits to build these modules were not found:
   _bsddb             _sqlite3           _ssl       _ctypes
   _tkinter           bsddb185           bz2
   dbm                gdbm               readline
   sunaudiodev
To find the necessary bits, look in setup.py in detect_modules() for the module's name.

直接安装需要的模块

yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel gcc gcc-c++ libffi-devel

启动webserver报错

lzma

Could not import the lzma module. Your installed Python is incomplete. Attempting to use lzma compression will result in a RuntimeError.

需要重新安装lzma

yum install -y xz-devel

重新编译安装python

gunicorn

FileNotFoundError: [Errno 2] No such file or directory: 'gunicorn'

将gunicorn的路径写到path

export PATH=${ 
   PATH}:/home/python3.9.6/bin
