python - 安装仅产生一个 .dist-info 文件夹(Pypi 打包)

Question

我按照 https://packaging.python.org/tutorials/packaging-projects/ 上的说明进行操作并创建了一个示例包。

但是，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

安装

抱歉，这个愚蠢的包名称，最初我创建了一个包含连字符的包，并认为这是根本原因。

此时我什至不确定这是环境问题还是软件包问题。

Windows 10、Python 3.7

Answer 1

目前您的项目结构如下所示:

/testvansjoerd
  setup.py
  setup.cfg
  README.md

但是，为了拥有可导入的最小包，您必须创建一个包(一个包含空 __init__.py 的文件夹)。项目结构如下所示:

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

上面的文件结构在packing documentation中也提到过.
