什么需要在setup.py中创建一个轮子？

Question

我有一个Python项目prj ，我们可以将其描述为文件夹和requirements.txt文件的集合：

[prj/fold1, prj/fold2,..., prj/foldN, prj/requirements.txt]

我想打包这个项目，以便它可以很容易地安装在其他计算机上。 我的理解是我需要添加一个setup.py文件，但有些东西我不明白。

我应该在setup.py文件中写什么才能创建一个wheel包？ 您能提供打包项目所需文件和命令的示例吗？

我有这个setup.py：

您无需在setup.py编写任何特殊内容即可创建轮子。 只要你的setup.py使用的是setuptools （无论如何都是这样），你只需编写一个正常的setup.py ，在你的系统上安装wheel包，然后运行python setup.py bdist_wheel 。
