Question

运行'python setup.py develop'或'python setup.py install'时，我会收到以下回溯。

Traceback (most recent call last):
  File "setup.py", line 38, in <module>

  File "/local/home/kassan1/venvs/some_env/local/lib/python2.7/site-packages/pbr/packaging.py", line 512, in override_get_script_args
    header = easy_install.get_script_header("", executable, is_wininst)
AttributeError: 'NoneType' object has no attribute 'get_script_header'

有趣的是，如果我重新运行与上面相同的命令，则安装成功。

只是为了解决问题，我尝试在导入和使用easy_install时将调试语句添加到pbr / packaging.py文件中。它在导入时看起来很好，但是当按照回溯在第512行访问时为None。

以下是我正在使用的要求文件：

pyyaml                                                                                                                                                                                                                                                                 
requests
termcolor
mock
nose
cached_property
argparse
unittest2
tox
stevedore
kombu

和setup.py脚本：

import ez_setup                                                                                                                                                                                                                                                        
ez_setup.use_setuptools('3.6')

import os

from setuptools import setup, find_packages

try:
    # workaround for http://bugs.python.org/issue15881
    import multiprocessing  # noqa
except ImportError:
    pass


def read(fname):
    return open(os.path.join(os.path.dirname(__file__), fname)).read()


def requirements():
    return read('requirements.txt').splitlines()


setup(
    name='MY_PROJECT',
    version='0.0.1',
    author="Noorez Kassam",
    long_description=read('README.rst'),
    install_requires=requirements(),
    entry_points={
        'console_scripts': [
            'myproj = myproj.myproj:main',
        ],
        'myproj.urloperations.download': [
            'file = myproj.filedownload:download'
        ],
    },  
    packages=find_packages(),
    test_suite='nose.collector',
)

Google上的快速搜索表明其他人遇到了我所看到的变化，但我无法找到问题的解决方案。

Answer 1

我遇到了一个非常类似的问题并找到了解决方法。

我也得到AttributeError: 'NoneType' object has no attribute 'get_script_header'

为我修复它的解决方法：在列表install_requires中，我在“luigi”之前有“tornado”。通过将订单切换为“luigi”然后“龙卷风”，这个错误就消失了。我看到你没有使用龙卷风或luigi，但我想排序仍然是这个问题的原因，因为你可以通过运行你的安装命令两次解决问题。

附加说明：在找到此解决方法之前，我尝试升级到最新的setuptools（v 5.8）。它没有解决这个错误。

Answer 2

我遇到了同样的问题，并通过更新setuptools版本来修复，即：

pip install --upgrade setuptools

运行setup.py脚本时，pbr中的NoneType错误
