Question

是否有人知道是否有任何工具用于打包将多个文件和模块用于单个脚本的Python项目？

Answer 1

制作.egg文件并安装或将其放在pythonpath上可能会解决您的问题 similar fellow

Answer 2

将其另存为python_header.py：

#!/bin/env/python
# -*- coding: ascii -*-
import os
import sys
import imp
import tarfile
import tempfile


RUN_MODULE = "__run__"
SENTINEL = 'RzlBTXhya3ljIzl6PFFkQiRKLntEdHF+c2hvWid0IX5NVlxWd' \
           'FxcJ0NWQ2xKVUI0TVEuNl0rWUtnKiRr'.decode('base64')


class FileOffset(object):
    def __init__(self, fileobj, offset=0):
        self._fileobj = fileobj
        self._offset = offset
        self._fileobj.seek(offset)

    def tell(self):
        return self._fileobj.tell() - self._offset

    def seek(self, position, whence=os.SEEK_SET):
        if whence == os.SEEK_SET:
            if position < 0: raise IOErrror("Negative seek")
            self._fileobj.seek(position + self._offset)
        else:
            oldposition = self._fileobj.tell()
            self._fileobj.seek(position, whence)
            if self._fileobj.tell() < self._offset:
                self._fileobj.seek(oldposition, os.SEEK_SET)
                raise IOError("Negative seek")

    def __getattr__(self, attrname):
        return getattr(self._fileobj, attrname)

    def __enter__(self, *args):
        return self._fileobj.__enter__(*args)

    def __exit__(self, *args):
        return self._fileobj.__exit__(*args)


class TarImport(object):
    def __init__(self, tarobj, tarname=None):
        if tarname is None:
            tarname = '<tarfile>'
        self._tarname = tarname
        self._tarobj = tarobj

    def find_module(self, name, path=None):
        module_path = os.path.join(*name.split('.'))
        package_path = os.path.join(module_path, '__init__')

        for path in [module_path, package_path]:
            for suffix, mode, module_type in imp.get_suffixes():
                if module_type != imp.PY_SOURCE:
                    continue
                member = os.path.join(path) + suffix
                try:
                    modulefileobj = self._tarobj.extractfile(member)
                except KeyError:
                    pass
                else:
                    return Loader(name, modulefileobj,
                                  "%s/%s" % (self._tarname, member),
                                  (suffix, mode, module_type))


class Loader(object):
    def __init__(self, name, fileobj, filename, description):
        self._name = name
        self._fileobj = fileobj
        self._filename = filename
        self._description = description

    def load_module(self, name):
        imp.acquire_lock()
        try:
            module = sys.modules.get(name)
            if module is None:
                module = imp.new_module(name)

            module_script = self._fileobj.read()
            module.__file__ = self._filename
            module.__path__ = []
            sys.modules[name] = module
            exec(module_script, module.__dict__, module.__dict__)
        finally:
            imp.release_lock()

        return module


def find_offset(fileobj, sentinel):
    read_bytes = 0
    for line in fileobj:
        try:
            offset = line.index(sentinel)
        except ValueError:
            read_bytes += len(line)
        else:
            return read_bytes + offset + len(sentinel)
    raise ValueError("sentinel not found in %r" % (fileobj, ))


if __name__ == "__main__":
    sys.argv[:] = sys.argv[1:]
    archive_path = os.path.abspath(sys.argv[0])
    archive_offset = find_offset(open(archive_path), SENTINEL)

    archive = FileOffset(open(archive_path), archive_offset)

    tarobj = tarfile.TarFile(fileobj=archive)
    importer = TarImport(tarobj, archive_path)

    sys.meta_path.insert(0, importer)

    importer.find_module(RUN_MODULE).load_module(RUN_MODULE)

将其另存为sh_header.sh：

#!/bin/sh

head -n @@TO@@ "$0" | tail -n +@@FROM@@ | python - "$0"

exit $?

将其另存为create_tarred_program.py：

#!/usr/bin/env python
# -*- coding: latin-1 -*-

import sys
import imp
import shutil

sh_filename, runner_filename, tar_archive, dst_filename = sys.argv[1:]

runner = imp.load_module("tarfile_runner",
                        open(runner_filename, 'U'),
                        runner_filename,
                        ('.py', 'U', imp.PY_SOURCE))



sh_lines = open(sh_filename, 'r').readlines()
runner_lines = open(runner_filename, 'r').readlines()

sh_block = ''.join(sh_lines)
runner_block = ''.join(runner_lines)

if runner.SENTINEL in runner_block or runner.SENTINEL in sh_block:
    raise ValueError("Can't have the sentinel inside the runner module")
if not runner_block.endswith('\n') or not sh_block.endswith('\n'):
    raise ValueError("Trailing newline required in both headers")

to_pos = len(sh_lines) + len(runner_lines)
from_pos = len(sh_lines) + 1

sh_block = sh_block.replace("@@TO@@", str(to_pos))
sh_block = sh_block.replace("@@FROM@@", str(from_pos))


dst = open(dst_filename, 'wb')

dst.write(sh_block)
dst.write(runner_block)
dst.write(runner.SENTINEL)

shutil.copyfileobj(open(tar_archive, 'rb'), dst)

dst.flush()
dst.close()

使用名为packages.tar的包创建tar存档。主模块应该被称为__run__.py，您永远不应该导入__main__。运行：

create_tarred_program.py sh_header.sh python_header.py packages.tar program.sh

Distrubute program.sh。

可以通过扩展的第一行避免对/bin/sh的依赖，但除了* nix之外，它仍然不会起作用，所以没有任何意义。
