python – pip找不到安装文件

__file__ = '<path to package>/setup.py'

from setuptools.command import egg_info

def replacement_run(self):
    self.mkpath(self.egg_info)

    installer = self.distribution.fetch_build_egg

    for ep in egg_info.iter_entry_points('egg_info.writers'):
        # require=False is the change we're making:

        writer = ep.load(require=False)

        if writer:
            writer(self,ep.name,egg_info.os.path.join(self.egg_info,ep.name))

    self.find_sources()

egg_info.egg_info.run = replacement_run

execfile(__file__)

在软件包的顶级目录中,没有setup.py,我放置了一个可以重现此行为的setup.py,但是chdir到包含“真正的”setup.py的目录,并在最后执行.

唯一的另一个问题是pip创建了一个目标“pip-egg-info”,它希望填充该目录,需要在具有“真实”setup.py的目录中创建一个符号链接.

新的顶级setup.py看起来像这样：

#! /usr/bin/env python

from os import chdir,symlink,getcwd
from os.path import join,basename,exists

filename = basename(__file__)

chdir("python")

setupdir = getcwd()

egginfo = "pip-egg-info"

if not exists(egginfo) and exists(join("..",egginfo)):
    symlink(join("..",egginfo),egginfo)

__file__ = join(setupdir,filename)

from setuptools.command import egg_info

def replacement_run(self):
    self.mkpath(self.egg_info)

    installer = self.distribution.fetch_build_egg

    for ep in egg_info.iter_entry_points('egg_info.writers'):
        # require=False is the change we're making:

        writer = ep.load(require=False)

        if writer:
            writer(self,ep.name))

    self.find_sources()

egg_info.egg_info.run = replacement_run

execfile(__file__)

它可能很脆弱,但应该继续工作,直到pip更改它生成的命令行python代码
