无论如何都不是一个完美的解决方案,但您可以设置一个安装后脚本来尝试安装软件包,如下所示:
from distutils.core import setup
from distutils import debug
from setuptools.command.install import install
class PostInstallExtrasInstaller(install):
extras_install_by_default = ['matplotlib', 'nothing']
@classmethod
def pip_main(cls, *args, **kwargs):
def pip_main(*args, **kwargs):
raise Exception('No pip module found')
try:
from pip import main as pip_main
except ImportError:
from pip._internal import main as pip_main
ret = pip_main(*args, **kwargs)
if ret:
raise Exception(f'Exitcode {ret}')
return ret
def run(self):
for extra in self.extras_install_by_default:
try:
self.pip_main(['install', extra])
except Exception as E:
print(f'Optional package {extra} not installed: {E}')
else:
print(f"Optional package {extra} installed")
return install.run(self)
setup(
name='python-package-ignore-extra-dep-failures',
version='0.1dev',
packages=['somewhat',],
license='Creative Commons Attribution-Noncommercial-Share Alike license',
install_requires=['requests',],
extras_require={
'extras': PostInstallExtrasInstaller.extras_install_by_default,
},
cmdclass={
'install': PostInstallExtrasInstaller,
},
)
