使用setup.py

Question

人们-这个问题困扰了我一段时间，并且仅在我使用的特定系统上。我的解决方法是在python虚拟环境之外安装python软件包，但我只想解决此问题。我已经寻找了数周的解决方案，但没有任何运气。我在Windows 10上使用Visual Studio Code。

需要帮助

我想解决以下问题，并避免上述解决方法，但一直无法纠正。对于造成该问题的根本原因的任何帮助将不胜感激。

问题

当我执行虚拟环境设置和pip安装时：

PS D:\Code\my-pkg> python -m venv venv
PS D:\Code\my-pkg> .\venv\Scripts\activate
(venv) PS D:\Code\my-pkg>pip install -e ".[test]" --force 

我应该能够从命令行运行“ publish.py”：

(venv) PS D:\Code\my-pkg> publish

但是，当我尝试运行它时，得到以下信息：

Traceback (most recent call last):
  File "D:\Code\my-pkg\venv\Scripts\publish.py", line 4, in <module>
    __import__('pkg_resources').require('my-pkg==0.2.0.0')
  File "C:\Python37\lib\site-packages\pkg_resources\__init__.py", line 3088, in <module>
    @_call_aside
  File "C:\Python37\lib\site-packages\pkg_resources\__init__.py", line 3072, in _call_aside
    f(*args, **kwargs)
  File "C:\Python37\lib\site-packages\pkg_resources\__init__.py", line 3101, in _initialize_master_working_set
    working_set = WorkingSet._build_master()
  File "C:\Python37\lib\site-packages\pkg_resources\__init__.py", line 574, in _build_master
    ws.require(__requires__)
  File "C:\Python37\lib\site-packages\pkg_resources\__init__.py", line 892, in require
    needed = self.resolve(parse_requirements(requirements))
  File "C:\Python37\lib\site-packages\pkg_resources\__init__.py", line 778, in resolve
    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'my-pkg==0.2.0.0' distribution was not found and is required by the application

解决方法

要解决此问题，我必须直接调用脚本：

(venv) PS D:\Code\my-pkg> .\src\Scripts\publish.py

产生的结果

Traceback (most recent call last):
  File "D:\Code\my-pkg\src\Scripts\publish.py", line 5, in <module>
    import click
ModuleNotFoundError: No module named 'click'

我可以通过在虚拟环境之外的系统上安装click来解决此问题。但是，我需要对我可能拥有的任何其他软件包依赖项执行此操作，这违背了使用virtualenv的目的。

setup.py

from setuptools import setup, find_packages
import os

build_num = os.environ.get('BUILD_NUMBER', '0')
version = "0.2.0.{}".format(build_num)

test_requirements = ['pytest', 'pylint', 'coverage', 'pytest-cov']

setup(
        name="my-pkg",
        version=version,
        packages=find_packages(),
        scripts=[
            'src/Scripts/publish.py'
        ],
        tests_require=test_requirements,
        install_requires=[
            'requests',
            'requests_negotiate_sspi',
            'wincertstore',
            'click'
            ],
        extras_require={
            'test':test_requirements
        }
     )

publish.py

import logging

import click

@click.group()
def tests():
    return 0

@tests.command()
@click.argument("endpoint")
@click.argument("results_path")
@click.option("--format", "-i", type=click.Choice("nunit", "junit"), required=True)
@click.option("--logging_level", "-l", type=click.Choice(logging.INFO, logging.DEBUG), default=logging.INFO, show_default=True)
def find(endpoint, results_path, format, logging_level):
    logging.basicConfig(level=logging_level)
    logging.info("Hello, friend")
