使用pip安装时检测setup.py中的源目录

时间:2019-09-24 14:27:22

标签: python-3.x pip setup.py

在从源目录安装软件包时,是否有办法在setup.py中找到原始源目录路径? 例如,我的源代码在

cd /home/jumbo/project/ ls -ltr Pipfile Pipfile.lock README.md bin src_code setup.py

在上述目录中,我运行'pip3 install .' 在setup.py中,我想捕获git源目录路径(/ home / jumbo / project /)并将git代码的提交哈希写入文件。

git源路径不是恒定的,因为它会随安装该设置的每个用户而变化。

git -C /home/jumbo/project/ rev-parse HEAD > hash.txt

感谢检查。

这是我的setup.py代码

import os.path
import subprocess
from setuptools import setup
from setuptools.command.install import install


class IW(install):
    def run(self):
        repo_path = os.path.dirname(os.path.realpath(__file__))
        print ("REPO_PATH:", repo_path)
        command = 'git -C ' + repo_path + ' rev-parse HEAD > hash.txt'
        execute_command = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE)
        execute_command.communicate()
        if execute_command.returncode != 0:
            raise OSError("Command %s failed" % command)
        install.run(self)

setup(name='jumbo_deploy',
      version='1.1.0',
      url='https://github.com/src/jumbo-deploy',
      license='Copyright Jumbo 2018',
      packages=['jumbo_deploy'],
      install_requires=[
          'argparse',
          'requests',
      ],
      zip_safe=False,
      package_data={'jumbo_deploy': ['hash.txt']},
      include_package_data=True,
      scripts=['bin/jumbo_deploy'],
      cmdclass={
          'install': IW,
      }
      )

+++++ END of my setup.py ++++


Currently with the above setup.py, my function run(self) is being executed after creating and changing the directory to some random 

user1 $ cd /home/jumbo/project/
user1 $ pip3 install . --upgrade -v

  Running setup.py (path:/private/var/folders/_w/sv2ms8pd0zl38l3lyy6f787w005lxf/T/pip-req-build-1df74t7f/setup.py) egg_info for package from file:///home/jumbo/project/
    Running command python setup.py egg_info

REPO_PATH:/private/var/folders/_w/sv2ms8pd0zl38l3lyy6f787w005lxf/T/pip-req-build-1df74t7f 

========
I'm expecting REPO_PATH:/home/jumbo/project
but seems before my setup code runs, it already changed the directory to /private/var/folders/_w/sv2ms8pd0zl38l3lyy6f787w005lxf/T/pip-req-build-1df74t7f

我敢肯定,使用自定义setuptools命令不能可靠地完成此操作,而使用自定义install命令则更不可能。确实(如您所正确注意到的那样),您几乎无法控制此命令的实际运行时间。

您可能应该更多地考虑自定义sdistbuilddevelop命令。这些通常直接在原始源目录中运行。您需要至少获得这3个(可能更多),才能处理所有情况,而这可能还不够。

接下来,您可以尝试使用自定义egg_info命令(如果我理解正确的话,或多或少所有命令都会在某个时候运行egg_info),但是我并没有对其进行过多研究要使所有情况都正确,可能要比看起来更棘手。

也请查看setuptools documentation on "Extending and Reusing Setuptools",以获取更多有关连接自定义代码的想法。

最后,您可以使用setuptools-scm,尤其是它的write_to选项来获得更好的运气,要么直接使用它,要么查看其代码以获取灵感。
