Python setuptools AttributeError 在 setup.cfg 配置中读取时出错

Question

我有以下setup.py文件：

import setuptools
import setuptools.config
_CONFIG = setuptools.config.read_configuration('setup.cfg')
setuptools.setup(
**_CONFIG
)

。和setup.cfg文件：

[metadata]
name = Example
version = 1.0.0
author = First Last
author_email = [e-mail]
home_page = https://www.github.com/firstlast/example
description = Example is an example project.
long_description = file: README.md
license_file = LICENSE
platform = any
keywords = example
classifiers =

[options]
zip_safe = False
include_package_data = True
python_requires = >= 2.7, != 3.0.*, != 3.1.*, != 3.2.*
packages =
example
setup_requires =
setuptools
install_requires =
requests
[options.extras_require]
dev =
ipython

为了安装模块，我正在执行以下操作：

1. 使用pipenv创建虚拟环境。

   $ pipenv --three
   

2. 激活虚拟环境。

   $ pipenv shell
   

3. 尝试在虚拟环境中安装示例模块。

   $ pip install .
   

当我执行步骤#3时，出现以下错误：

Processing /Users/firstlast/Stuff/learn/python/setuptools/example
Complete output from command python setup.py egg_info:

似乎setuptools正在使用zip_file指定的值作为字典，而实际上它是一个布尔值。

有人可以解释一下我做错了什么吗？

注意

pipenv --three在虚拟环境中安装的Python版本是Python 3.7。

我已经确认在虚拟环境中，设置工具是最新的(即pip install --upgrade setuptools=> "要求已经是最新的：...(40.4.3("(，以及点本身(即pip --version== 18.0(。

这不是setup.cfg的使用方式。read_configuration()仅供想要读取setup.cfg的非安装工具代码使用;没有必要用你自己的setup.py来称呼它，因为setup()自己会读取和处理setup.cfg。 只需将您的setup.py更改为：

import setuptools
setuptools.setup()
