Question

我正在安装tweepy，但是我遇到了关于pip.req的错误。我安装了pip，但由于某种原因pip.req仍然无法找到。我在网上进行了大量研究，我发现的最多是关于zapo（？）和python 2.7之间不兼容的问题导致其他用户出现同样的错误。但是，关于如何解决问题的讨论还不清楚。谢谢！

$ python2 setup.py install
Traceback (most recent call last):
  File "setup.py", line 5, in <module>
    from pip.req import parse_requirements
ImportError: No module named pip.req

Answer 1

由于点数10的变化，最近发生了这种情况。

修复非常简单。你可能有类似的东西：

from pip.req import parse_requirements

将其更改为：

try: # for pip >= 10
    from pip._internal.req import parse_requirements
except ImportError: # for pip <= 9.0.3
    from pip.req import parse_requirements

应该这样做。

Answer 2

我降级到了9.0.3，一切对我来说都很有效。降级点的命令是

python -m pip install pip==9.0.3

Answer 3

如果你有这个代码，它看起来会起作用：

def parse_requirements(filename):
    """ load requirements from a pip requirements file """
    lineiter = (line.strip() for line in open(filename))
    return [line for line in lineiter if line and not line.startswith("#")]

这样做：

创建目录pip/
添加空文件pip/__init__.py
添加文件pip/req.py
将上面的代码放入pip/req.py：
修改setup.py
中的行
reqs = install_reqs

Answer 4

使用以下内容替换setup.py的内容，而不是导入函数并可能遇到更多问题：

#!/usr/bin/env python
#from distutils.core import setup
import re, uuid
from setuptools import setup, find_packages

def parse_requirements(filename):
    """ load requirements from a pip requirements file """
    lineiter = (line.strip() for line in open(filename))
    return [line for line in lineiter if line and not line.startswith("#")]


VERSIONFILE = "tweepy/__init__.py"
ver_file = open(VERSIONFILE, "rt").read()
VSRE = r"^__version__ = ['\"]([^'\"]*)['\"]"
mo = re.search(VSRE, ver_file, re.M)

if mo:
    version = mo.group(1)
else:
    raise RuntimeError("Unable to find version string in %s." % (VERSIONFILE,))

install_reqs = parse_requirements('requirements.txt')
reqs = install_reqs

setup(name="tweepy",
      version=version,
      description="Twitter library for python",
      license="MIT",
      author="Joshua Roesslein",
      author_email="tweepy@googlegroups.com",
      url="http://github.com/tweepy/tweepy",
      packages=find_packages(exclude=['tests']),
      install_requires=reqs,
      keywords="twitter library",
      classifiers=[
          'Development Status :: 4 - Beta',
          'Topic :: Software Development :: Libraries',
          'License :: OSI Approved :: MIT License',
          'Operating System :: OS Independent',
          'Programming Language :: Python',
          'Programming Language :: Python :: 2',
          'Programming Language :: Python :: 2.6',
          'Programming Language :: Python :: 2.7',
          'Programming Language :: Python :: 3',
          'Programming Language :: Python :: 3.3',
          'Programming Language :: Python :: 3.4',
      ],
      zip_safe=True)

请注意，会话参数已从parse_requirements调用中删除。

Answer 5

我在Python 3.7 + pip 18.0中遇到了非常相似的问题：

Traceback (most recent call last):
  File "/usr/local/bin/pip-compile", line 7, in <module>
    from piptools.scripts.compile import cli
  File "/usr/local/lib/python3.7/site-packages/piptools/scripts/compile.py", line 11, in <module>
    from pip.req import InstallRequirement, parse_requirements
ModuleNotFoundError: No module named 'pip.req'

解决方案是将pip-tools从1.10升级到2.0：

pip install -U pip-tools

Answer 6

我遇到了同样的问题。要安装pip，你需要遵循这个https://pypi.python.org/pypi/setuptools一旦你得到easy_install我首先安装了pip，然后运行以下命令。

sudo easy_install pip
sudo python setup.py install

容易。

没有名为pip.req的模块
