我们为Twitter应用程序编写了一个小型包装，并将此信息发布到http://pypi.python.org。但是setup.py仅包含一个用于指定作者的电子邮件/姓名的字段。我如何在以下字段中指定多个贡献者/电子邮件列表，因为我们希望此软件包以我们的名字列出，与它在http://rubygems.org中显示的方式非常相似。

   author='foo',
   author_email='foo.bar@gmail.com',

据我所知，setuptools不支持使用字符串列表来指定多个作者。最好的选择是在单个字符串中列出作者：

author='Foo Bar, Spam Eggs',
author_email='foobar@baz.com, spameggs@joe.org',

我不确定PyPIauthor_email是否会验证该字段，因此您可能会遇到麻烦。无论如何，我建议您将这些作者限制为一个作者，并在文档或说明中提及所有贡献者。

[编辑]一些来源：

实际上，这已被注册为bug，但似乎未实现对多位作者的支持。这是一个替代解决方案。这是有关如何为具有多个作者的项目提供联系电子邮件的想法。

我有点want带@modocache的答案，以防您需要一些细节。

在整个答案中，我将引用该FOO-PYTHON-ENV\Lib\distutils\dist.py文件的python3.6版本

要重申，您不能在author字段中使用列表。原因如下：

剧透：属于DistributionMetadata该类的两种方法是原因-

def _read_field(name):
    value = msg[name]
    if value == 'UNKNOWN':
        return None
    return value

def _read_list(name):
    values = msg.get_all(name, None)
    if values == []:
        return None
    return values

如果您尝试在author字段中粘贴列表，就会在这里遇到错误：

class DistributionMetadata:

#*...(R E D A C T E D)...*#

    def read_pkg_file(self, file):
        """Reads the metadata values from a file object."""
    #*...(R E D A C T E D)...*#
        # ####################################
        # Note the usage of _read_field() here
        # ####################################
        self.name = _read_field('name')
        self.version = _read_field('version')
        self.description = _read_field('summary')
        # we are filling author only.
        self.author = _read_field('author')
        self.maintainer = None
        self.author_email = _read_field('author-email')
        self.maintainer_email = None
        self.url = _read_field('home-page')
        self.license = _read_field('license')
    #*...(R E D A C T E D)...*#
        # ###################################
        # Note the usage of _read_list() here
        # ###################################
        self.platforms = _read_list('platform')
        self.classifiers = _read_list('classifier')
    #*...(R E D A C T E D)...*#

＆这就是整个事情：
