Unpacking ./.tox/dist/myproject-0.0.1.zip

    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
  File "<string>", line 16, in <module>
  File "/tmp/pip-azSQM4-build/setup.py", line 40, in <module>
    license=open("LICENSE").read(),
IOError: [Errno 2] No such file or directory: 'LICENSE'

该文件应该包含在分发版中，因为它在 setup() 的命名参数 package_data 中被提及:

setup(
    ...
    long_description=open("README.rst").read(),
    ...
    license=open("LICENSE.txt").read(),
    ...
    package_data={'': ['LICENSE.txt', 'README.rst', 'requirements.txt']},
    ...
    install_requires=open("requirements.txt").read().splitlines(),

请注意，我们使用的是 tox:

    tests_require=['tox'],
    cmdclass={'test': Tox},
)

及更早的版本:

class Tox(TestCommand):
    """Enables `python setup.py test` to run tox."""
    def finalize_options(self):
        TestCommand.finalize_options(self)
        self.test_args = []
        self.test_suite = True

    def run_tests(self):
        #import here, cause outside the eggs aren't loaded
        import tox
        try:
            tox.cmdline(self.test_args)
        except SystemExit as exception:
            sys.exit(exception.code)

我没有成功尝试使用这样的绝对路径:

long_description=open(os.path.join(os.path.dirname(os.path.realpath(__file__)), \
                      "README.rst")).read(),

env= 表明PWD 和TRAVIS_BUILD_DIR 是一样的，所以open('LICENSE')应该可以工作，因为它位于 Git 目录的根目录中。

在本地通过 Tox，所有 Python 版本的所有测试都成功。

Travis-Lint 接受我的 .travis.yml:

$ travis-lint
Hooray, /home/bengt/MyTeam/MyProject.travis.yml seems to be solid!

Answer 1

在项目根目录下创建MANIFEST.in并放置

include README.rst
include LICENSE.txt
include requirements.txt

里面？
