Python Pip未获取自定义安装cmdclass

所以我发现 我的问题是，但出于某种原因，它不起作用：

$cat/tmp/testinstall/setup.py

：

from setuptools.command.install import install

from setuptools import setup


class verifying_install(install):
    def run(self):
        print "running........"
        install.run(self)
        print "verifying........"


setup(name='test',
      version='1',
      py_modules=['test'],
      include_package_data=True,
      zip_safe=True,
      cmdclass={'install': verifying_install}
)

但是，即使

setup.py安装

有效：

➜  /tmp/testinstall
$ mktmpenv && cd -
This is a temporary environment. It will be deleted when you run 'deactivate'.

目录的pip安装不起作用：

有人知道这里发生了什么吗？

试试：

pip install dist/test-1.tar.gz -U

我遇到了同样的问题。尝试运行

pip安装-vvv

-可能是消息被隐藏了（我不知道为什么-不是pip专家！）。在任何情况下，您都可以通过将自定义代码打印到某个文件而不是打印到标准输出来确认代码是否正在运行。

我刚才遇到了这个问题。看起来有许多不同的命令可以翻译成

pip install my package

setup.py安装

setup.py egg\u info

setup.py develope

所以你需要处理这些不同的案件

from setuptools.command.install import install
from setuptools.command.develop import develop
from setuptools.command.egg_info import egg_info

'''
BEGIN CUSTOM INSTALL COMMANDS
These classes are used to hook into setup.py's install process. Depending on the context:
$ pip install my-package

Can yield `setup.py install`, `setup.py egg_info`, or `setup.py develop`
'''


def custom_command():
    import sys
    if sys.platform in ['darwin', 'linux']:
        os.system('./custom_command.sh')


class CustomInstallCommand(install):
    def run(self):
        install.run(self)
        custom_command()


class CustomDevelopCommand(develop):
    def run(self):
        develop.run(self)
        custom_command()


class CustomEggInfoCommand(egg_info):
    def run(self):
        egg_info.run(self)
        custom_command()

'''
END CUSTOM INSTALL COMMANDS 
'''

setup(
    ...
    cmdclass={
        'install': CustomInstallCommand,
        'develop': CustomDevelopCommand,
        'egg_info': CustomEggInfoCommand,
    },
    ...
)

我已经试过了，但是在尝试从pypi安装sdist包时，它不起作用。见相关讨论。只有本地安装和直接从git存储库安装似乎是可行的

pip

使

setup.py的输出静音
