迁移setup.py到pyproject.toml后，pip安装aanalytics2仅生成dist-info致无法导入

核心问题：包源码未被正确识别 #

你的pyproject.toml里[tool.setuptools.packages.find]的where参数配置错误，导致setuptools找不到实际的包代码。

当前错误配置：

[tool.setuptools.packages.find]
where = ["aanalytics2"]

你的pyproject.toml位于./aanalytics2/目录下，而包源码就在该目录下的aanalytics2/子文件夹里，所以where应该指向当前目录（.），而非子目录名。

其他需修正的配置项 #

1. package-data 包名占位符错误
   配置里的mypkg是默认占位符，要替换成你的实际包名aanalytics2，才能正确包含pickle文件：

   [tool.setuptools.package-data]
   aanalytics2 = ["*.pickle"]
   

2. 移除多余的optional-dependencies配置
   [project.optional-dependencies]下的dynamic = ["version"]完全多余，直接删掉——版本动态配置只需要在[project]下声明一次即可。

3. license与classifiers不一致
   你在[project]里声明的是Apache License 2.0，但classifiers里写的是GPLv3，建议统一成其中一个，避免混淆。

4. 依赖项优化

   • pathlib是Python 3.4+标准库，无需作为依赖声明；
   • pytest是测试依赖，应该放到[project.optional-dependencies]的测试分组里，而非主依赖：

     [project.optional-dependencies]
     test = ["pytest"]
     

修正后的完整pyproject.toml示例 #

[build-system]
requires = ["setuptools", "setuptools-scm"]
build-backend = "setuptools.build_meta"

[project]
name = "aanalytics2"
authors = [
    {name = "Julien Piccini", email = "piccini.julien@gmail.com"},
]
description = "Adobe Analytics API 2.0 and 1.4 python wrapper"
readme = "README.md"
requires-python = ">=3.7"
keywords = ["adobe", "analytics", "API", "python"]
license = {text = "Apache License 2.0"}
classifiers = [
    "Intended Audience :: Developers",
    "License :: OSI Approved :: Apache Software License",
    "Operating System :: OS Independent",
    "Programming Language :: Python",
    "Topic :: Scientific/Engineering :: Information Analysis",
    "Programming Language :: Python :: 3.7",
    "Programming Language :: Python :: 3.8",
    "Programming Language :: Python :: 3.9",
    "Development Status :: 4 - Beta"
]
dependencies = [
    'pandas>=0.25.3',
    'pathlib2; python_version < "3.4"',
    'requests',
    'PyJWT[crypto]',
    "dicttoxml",
    "openpyxl>2.6.0"
]
dynamic = ["version"]

[project.urls]
homepage = "https://github.com/pitchmuc/adobe-analytics-api-2.0"
changelog = "https://github.com/pitchmuc/adobe-analytics-api-2.0/blob/master/docs/releases.md"

[tool.setuptools]
include-package-data = true

[tool.setuptools.packages.find]
where = ["."]

[tool.setuptools.package-data]
aanalytics2 = ["*.pickle"]

[project.optional-dependencies]
test = ["pytest"]

验证修复效果 #

1. 先卸载已安装的错误版本：pip uninstall -y aanalytics2
2. 在pyproject.toml所在目录执行本地安装：pip install .
3. 检查site-packages目录，现在应该同时存在aanalytics2/包文件夹和aanalytics2-0.3.4.dist-info/文件夹
4. 测试导入：python -c "import aanalytics2; print(aanalytics2.__version__)"
