它不能接受文件句柄。install_requires参数只能是字符串或字符串列表。

当然，您可以在设置脚本中读取您的文件，并将其作为字符串列表传递给install_requires。

import os
from setuptools import setup

with open('requirements.txt') as f:
    required = f.read().splitlines()

setup(...
install_requires=required,
...)

以下接口在pip 10中已弃用:

from pip.req import parse_requirements
from pip.download import PipSession

所以我把它转换成简单的文本解析:

with open('requirements.txt', 'r') as f:
    install_reqs = [
        s for s in [
            line.split('#', 1)[0].strip(' \t\n') for line in f
        ] if s != ''
    ]

在Travis中安装当前包。这避免了使用requirements.txt文件。 例如:

language: python
python:
  - "2.7"
  - "2.6"
install:
  - pip install -q -e .
script:
  - python runtests.py

从皮普。req导入parse_requirements对我来说不工作，我认为它是我的requirements.txt中的空白行，但这个函数确实工作

def parse_requirements(requirements):
    with open(requirements) as f:
        return [l.strip('\n') for l in f if l.strip('\n') and not l.startswith('#')]

reqs = parse_requirements(<requirements_path>)

setup(
    ...
    install_requires=reqs,
    ...
)

我为此创建了一个可重用函数。它实际上解析需求文件的整个目录，并将它们设置为extras_require。
