使用 setuptools 在安装模式下找到但不在开发模式下的模块 [英] Module found in install mode but not in develop mode using setuptools

问题描述

我是第一次使用 setuptools，并尝试打包我的代码，以便其他人可以轻松地开发它.我在虚拟环境中运行所有东西.

I'm using setuptools for the first time, and trying to package my code so that others can easily develop it. I'm running everything in a virtual environment.

小问题:如何在运行 python setup.py develop 时更改 egg-link 指向的目录?

Short question: How do I change the directory that the egg-link points to when I run python setup.py develop?

长问题:我正在开发的模块名为cops_and_robots.当我运行 python setup.py install 时，一切正常，我可以导入我的 cops_and_robots 模块.但是，当我运行 python setup.py develop 时，运行 import cops_and_robots 失败，因为 cops_and_robots.egg-link 指向错误的目录:

Long question: The module I'm developing is called cops_and_robots. When I run python setup.py install, things work fine and I'm able to import my cops_and_robots module. However, when I run python setup.py develop, running import cops_and_robots fails because the cops_and_robots.egg-link points to the wrong directory:

(cops_and_robots)Antares:cops_and_robots nick$ cat ~/virtual_environments/cops_and_robots/lib/python2.7/site-packages/cops-and-robots.egg-link 
/Users/nick/Downloads/cops_and_robots/
.

目录结构如下:

|____Downloads
| |____cops_and_robots # the whole package directory
| | |____...
| | |____requirements.txt
| | |____setup.py
| | |____src
| | | |____cops_and_robots # the python package directory
| | | |______init.py__
| | |____...

还有我的setup.py:

from setuptools import setup, find_packages
import ez_setup
ez_setup.use_setuptools()

setup(
    # Author information and Metadata
    name='cops_and_robots',

    # Package data
    packages=find_packages('src'),
    package_dir={'cops_and_robots':'src/cops_and_robots'},
    include_package_data=True,
    platforms='any',
    requires=['std_msgs','rospy'],
    tests_require=['pytest'],
    install_requires=[i.strip() for i in open("requirements.txt").readlines()],
)

手动修复只是将 src/cops_and_robots 附加到 cops_and_robots.egg-link 文件，但我正在寻找一种更优雅的方法来做到这一点.

The manual fix is to just append src/cops_and_robots to the cops_and_robots.egg-link file, but I'm looking for a more elegant way to do that.

推荐答案

对于您的迫切需要来说可能为时已晚，但是 setuptools devel 安装已经有这个问题很久了.幸运的是，有一个简单的解决方法可能适用于您的情况.尝试改变:

Probably too late for your immediate need, but setuptools devel installation has had this problem for a long time. Luckily, there is an easy workaround that might work in your case. Just try changing:

# Package data
packages=find_packages('src'),
package_dir={'cops_and_robots':'src/cops_and_robots'},

到

# Package data
packages=find_packages('src'),
package_dir={'':'src'},

在您的 setup.py 脚本中.

这种情况在 setuptools setup.py devel 和 pip install -e 中应该可以很好地工作.

That case should work well enough with setuptools setup.py devel and thus with pip install -e as well.
