安装结果只有一个 .dist-info 文件夹（Pypi Packaging）

Question

我按照https://packaging.python.org/tutorials/packaging-projects/上的说明创建了一个示例包。

但是，在安装时，它只会在 Python 的 site_packages 文件夹中创建一个 testvansjoerd-0.0.2.dist-info 文件夹。 因此在执行import testvansjoerd时给我一个错误

示例包： https : //test.pypi.org/project/testvansjoerd/

我使用python -m pip -v install --index-url https://test.pypi.org/simple/ testvansjoerd==0.0.2

日志输出：

Config variable 'Py_DEBUG' is unset, Python ABI tag may be incorrect
Config variable 'WITH_PYMALLOC' is unset, Python ABI tag may be incorrect

对不起，这个愚蠢的包名称，最初我创建了一个带有连字符的包，并认为这是根本原因。

在这一点上，我什至不确定这是环境问题还是包的问题。

Windows 10，Python 3.7

Answer 1

当前，您的项目结构如下：

/testvansjoerd
  setup.py
  setup.cfg
  README.md

但是，为了拥有可以导入的最小软件包，您必须创建一个（带有空__init__.py的文件夹）。 项目结构将如下所示：

/testvansjoerd
  /testvansjoerd
    __init__.py
  setup.py
  setup.cfg
  README.md

包装文件中也提到了上述文件结构。

Answer 2

如果有人仍然遇到这个问题。

如果你有这样的项目结构：

/project
   /src
      /package_name
         __init__.py
         main.py
         ...
   setup.py
   README.md
   ...

只需尝试在您的安装脚本中更改packages= ：

packages=setuptools.find_packages('src/')

所以它将在src搜索包
