如何从egg文件加载配置文件？我正在尝试在Airflow上运行作为egg文件打包的python代码。在代码中，它试图加载一个无法在Airflow上运行的config.json文件。我想问题是它试图从egg文件中读取文件，但由于它被压缩了，所以找不到它。我更新了setup.py如下，以确保配置文件在pckage:中
from setuptools import find_packages, setup
setup(
name='tv_quality_assurance',
packages=find_packages(),
version='0.1.0',
description='Quality checks on IPTV linear viewing data',
author='Sarah Berenji',
data_files=[('src/codes', ['src/codes/config.json'])],
include_package_data=True,
license='',
)
现在它抱怨config_file_path不是一个目录：
NotADirectoryError: [Errno 20] Not a directory: '/opt/artifacts/project-0.1.0.dev8-py3.6.egg/src/codes/config.json'
我检查了路径，json文件就在那里。以下是我的代码，其中添加了一些打印语句以进行调试，这表明它不会将config_file_path视为文件或目录：
dir_path = os.path.dirname(__file__)
config_file_path = dir_path + '/config.json'
print(f"config_file_path = {config_file_path}")
print(f"relpath(config_file_path) = {os.path.relpath(config_file_path)}")
if not os.path.isfile(config_file_path):
print(f"{config_file_path} is not a file")
if not os.path.isdir(config_file_path):
print(f"{config_file_path} is not a dir")
with open(config_file_path) as json_file:
config = json.load(json_file)
它返回以下输出：
config_file_path = /opt/artifacts/project-0.1.0.dev8-py3.6.egg/src/codes/config.json
relpath(config_file_path) = ../../artifacts/project-0.1.0.dev8-py3.6.egg/src/codes/config.json
/opt/artifacts/project-0.1.0.dev8-py3.6.egg/src/codes/config.json is not a file
/opt/artifacts/project-0.1.0.dev8-py3.6.egg/src/codes/config.json is not a dir
Traceback (most recent call last):

在我的下一次尝试中，我尝试使用importlib_resources，但最终出现了一个奇怪的错误，即模块没有安装，但日志显示它是由pip:ModuleNotFoundError: No module named 'importlib_resources'成功安装的
import importlib_resources
config_file = importlib_resources.files("src.codes") / "config.json"
with open(config_file) as json_file:
config = json.load(json_file)
我只是设法使用pkg_resources:
config_file = pkg_resources.resource_stream('src.codes', 'config.json')
config = json.load(config_file)
