读取 setup.cfg 配置时的 Python setuptools AttributeError答案

【问题标题】：Python setuptools AttributeError when reading in setup.cfg configuration读取 setup.cfg 配置时的 Python setuptools AttributeError

【问题描述】：

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 = first.last@example.com
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

[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：

使用 pipenv 创建一个虚拟环境。
```
$ pipenv --three
```
激活虚拟环境。
```
$ pipenv shell
```
尝试在虚拟环境中安装example模块。
```
$ pip install .
```

当我执行第 3 步时，我收到以下错误：

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

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/jw/f2zw3cls6xj20dld1h8st4jc0000gp/T/pip-req-build-rcbbm11x/

setuptools 似乎将zip_file 指定的值用作字典，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版本为Python 3.7。

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

【解决方案1】：

setup.cfg 不是这样使用的。 read_configuration() 仅供非setuptools 代码使用，希望读取setup.cfg；无需在您自己的setup.py 中调用它，因为setup() 会自行读取和处理setup.cfg。只需将您的 setup.py 更改为：

import setuptools

setuptools.setup()

啊，非常感谢！对不起这个愚蠢的问题。我浏览了 setuptools “readthedocs”，但发现有些不清楚。
