我构建了一个python包并上传到pypi。它安装得很好，但在导入时我会收到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。尽管都在(新的(conda-envs中(。我上一次出现这个错误是因为文件夹的名称不正确，但这里的情况并非如此。GitHub repo位于分支和用于构建whl的文件夹中。
有什么想法吗？
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

ModuleNotFoundError出现在jupyter控制台、jupyterlab笔记本和终端python中。确认内核指向正确的conda目录(尽管我认为没有必要进行故障排除，因为错误在不同的机器上复制(：
(pillar_env) jupyter-pomkos@jupyterubuntu:~$ nano ~/.local/share/jupyter/kernels/pillar_env/kernel.json

"argv": [
"/home/jupyter-pomkos/.conda/envs/pillar_env/bin/python",
"-m",

您当前的setup.cfg如下所示：
[options]
package_dir =
= pillaralgos
packages = find:
# ...
[options.packages.find]
where = pillaralgos
将其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:
# ...
如果我没有错的话，package_dir字段以及整个[options.packages.find]部分都不是必需的。
对于所有的包构建/发布，切换到poetry，他们似乎头脑清醒。
据说是用python内置的python3 -m build和python twine upload dist/*命令运行的：
- 确保本地和github上的所有文件夹中都有
__init__.py - 确保文件夹结构正确<---这就是问题所在
默认python命令的文件夹结构应为：
|-- pypi
|-- src # <---- this folder can be named pillaralgos, but still needed another pillaralgos subfolder
|-- pillaralgos # <----- this is needed
|-- helpers
|-- __init__.py
|-- data_handler.py
|-- __init__.py
|-- algoXX.py
|-- LICENSE
|-- pyproject.toml
|-- README.md
|-- setup.cfg
poetry开箱即用。文件夹结构：
|-- pypi
|-- pillaralgos # <---- note that poetry didn't require an additional subfolder
|-- helpers
|-- __init__.py
|-- data_handler.py
|-- graph_helpers.py
|-- sanity_checks.py
|-- __init__.py # must include version number
|-- algoXX.py # all algorithms in separate files
|-- LICENSE
|-- README.md
|-- pyproject.toml # must include version number
