python没有安装setuptools的install_requires中列出的依赖项 [英] python is not installing dependencies listed in install_requires of setuptools

问题描述

我写了一个依赖于openpyxl的python模块.我希望使用setuptools将openpxyl自动安装为依赖项. 我读到，执行此操作的正确方法是在setup.py脚本中包含以下内容:

I have written a python module that depends on openpyxl. I want openpxyl to be installed as a dependency automatically using setuptools. I read that the proper way to do this is to include the following in the setup.py script:

setup(name='methpipe',
    version=find_version("lala", "__init__.py"),
    description='Utilities',
    author='Jonathan T',
    author_email='[e-mail]',
    url='https://git.com...',
    packages=find_packages(),
    install_requires=[
        'openpxyl = 2.3.3',
    ],
    scripts=["bin/submit_run_full.py"],
    cmdclass=dict(install=my_install)
)

所以我用python setup.py sdist打包了我的模块，取出* .tar.gz文件，解压缩，然后运行python setup.py install，而openpyxl没有安装！

So I packaged up my module with python setup.py sdist, took the *.tar.gz file, unzipped it, and then ran python setup.py install, and openpyxl is NOT installing!!!

我在做什么错了?

推荐答案

我注意到当您使用带有'cmdclass'键的覆盖'install'时.下面的模式也使我摆脱了依赖关系.

I notice when you use override 'install' with a 'cmdclass' key. The pattern below also left me with uninstalled dependencies.

Custom_Install(install):
    def run(self):
        # some custom commands
        install.run(self) 

将依赖项添加到setup_requires中对我来说不起作用，因此最终我只在custom install命令中完成了自己的pip安装.

Adding the dependencies into setup_requires didn't work for me so in the end I just did my own pip install in the custom install command..

def pip_install(package_name):
    subprocess.call(
        [sys.executable, '-m', 'pip', 'install', package_name]
    )
