setuptools - 我构建了一个python包并上传到pypi。可以安装但不能导入 : ModuleNotFoundError

Question

我构建了一个python包并上传到pypi .它安装得很好，但是在导入时我得到 ModuleNotFound错误。该错误在全新的 conda 环境中复制，在不同的机器上(Ubuntu、MacOS、Windows。虽然都在(新)conda 环境中)。我最后一次出现此错误是因为文件夹命名不正确，但这里并非如此。 GitHub repo在用于构建 whl 的分支和文件夹中。
有任何想法吗？
包是使用构建和安装的

python3 -m build
python3 -m twine upload dist/*
pip install pillaralgos

(pillar_env) jupyter-pomkos@jupyterubuntu:~$ python
Python 3.8.8 (default, Feb 24 2021, 21:46:12)

---------------------------------------------------------------------------
>>> import pillaralgos
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'pillaralgos'
>>> 

它出现在 pip list

(pillar_env) jupyter-pomkos@jupyterubuntu:~$ pip list
Package            Version
------------------ -------------------
# Truncated
pexpect            4.8.0

pillaralgos        1.0.1
Pillow             8.2.0
pip                21.0.1

sys.path确实包括安装库的目录。

>>> import sys
>>> sys.path

>>> 

pip show说它安装在正确的环境和目录中。

(pillar_env) jupyter-pomkos@jupyterubuntu:~$ pip show pillaralgos

ModuleNotFoundError出现在 jupyter 控制台、jupyterlab notebook 和终端 python 中。确认内核指向正确的 conda 目录(虽然我认为这个故障排除没有必要，因为错误是在不同的机器上复制的):

(pillar_env) jupyter-pomkos@jupyterubuntu:~$ nano ~/.local/share/jupyter/kernels/pillar_env/kernel.json
---------------------------------------------------------------------------
{
 "argv": [
  "/home/jupyter-pomkos/.conda/envs/pillar_env/bin/python",

 ],

}

您当前的 setup.cfg 看起来像这样:

[options]
package_dir =
    = pillaralgos
packages = find:
# ...

[options.packages.find]
where = pillaralgos

将此与您的项目目录结构进行比较，在我看来，您应该更改为以下内容:

[options]
packages = find:
# ...

如果我没记错的话， package_dir领域以及整个 [options.packages.find]部分是没有必要的。
