How to write setup.py to include a git repo as a dependency

问题

I am trying to write setup.py for my package. My package needs to specify a dependency on another git repo.

This is what I have so far:

from setuptools import setup, find_packages

setup(
    name='abc',
    packages=find_packages(),
    url='https://github.abc.com/abc/myabc',
    description='This is a description for abc',
    long_description=open('README.md').read(),
    install_requires=[
        "requests==2.7.0",
        "SomePrivateLib>=0.1.0",
        ],
    dependency_links = [
     "git+git://github.abc.com/abc/SomePrivateLib.git#egg=SomePrivateLib",
    ],
    include_package_data=True,
)

When I run:

pip install -e https://github.abc.com/abc/myabc.git#egg=analyse

I get

Could not find a version that satisfies the requirement SomePrivateLib>=0.1.0 (from analyse) (from versions: ) No matching distribution found for SomePrivateLib>=0.1.0 (from analyse)

What am I doing wrong ?

回答1:

You can find the right way to do it here.

dependency_links=['http://github.com/user/repo/tarball/master#egg=package-1.0']

The key is not to give a link to a git repository, but a link to a tarball. Github creates a tarball of the master branch for you if you append /tarball/master as shown above.

After digging through the pip issue 3939 linked by @muon in the comments above and then the PEP-508 specification, I found success getting my private repo dependency to install via setup.py using this specification pattern in install_requires (no more dependency_links):

install_requires = [
  'some-pkg @ git+ssh://git@github.com/someorgname/pkg-repo-name@v1.1#egg=some-pkg',
]

The @v1.1 indicates the release tag created on github and could be replaced with a branch, commit, or different type of tag.

Unfortunately the other answer does not work with private repositories, which is one of the most common use cases for this. I eventually did get it working with a setup.py file that looks like this:

from setuptools import setup, find_packages

setup(
    name = 'MyProject',
    version = '0.1.0',
    url = '',
    description = '',
    packages = find_packages(),
    install_requires = [
        # Github Private Repository - needs entry in `dependency_links`
        'ExampleRepo'
    ],

    dependency_links=[
        # Make sure to include the `#egg` portion so the `install_requires` recognizes the package
        'git+ssh://git@github.com/example_organization/ExampleRepo.git#egg=ExampleRepo-0.1'
    ]
)

Newer versions of pip make this even easier by removing the need to use "dependency_links"-

from setuptools import setup, find_packages

setup(
    name = 'MyProject',
    version = '0.1.0',
    url = '',
    description = '',
    packages = find_packages(),
    install_requires = [
        # Github Private Repository
        'ExampleRepo @ git+ssh://git@github.com/example_organization/ExampleRepo.git#egg=ExampleRepo-0.1'
    ]
)

A more general answer, to get the information from the requeriments.txt file I do:

from setuptools import setup, find_packages
from os import path

loc = path.abspath(path.dirname(__file__))

with open(loc + '/requirements.txt') as f:
    requirements = f.read().splitlines()

required = []
dependency_links = []
# do not add to required lines pointing to git repositories
EGG_MARK = '#egg='
for line in requirements:
    if line.startswith('-e git:') or line.startswith('-e git+') or \
            line.startswith('git:') or line.startswith('git+'):
        if EGG_MARK in line:
            package_name = line[line.find(EGG_MARK) + len(EGG_MARK):]
            required.append(package_name)
            dependency_links.append(line)
        else:
            print('Dependency to a git repository should have the format:')
            print('git+ssh://git@github.com/xxxxx/xxxxxx#egg=package_name')
    else:
        required.append(line)

setup(
    name='myproject',  # Required
    version='0.0.1',  # Required
    description='Description here....',  # Required
    packages=find_packages(),  # Required
    install_requires=required,
    dependency_links=dependency_links,
)
