如何使用 setuptools 安装 python cli 脚本而不重复？

我有 2 个可以从 shell 中使用的 Python 脚本，因为它们归功于 argparse。

setup.py 的相关部分：

setup(
    # (...)
    zip_safe=True,
    scripts=['bin/bgce.py', 'bin/sizes.py'],
    packages=find_packages(),
    data_files=data_files,
    entry_points = {
        'console_scripts': [
            'bgce = bgce:main',
            'sizes = sizes:main',]
    }
)

我最终在 /usr/local/bin 中得到 bgce、bgce.py、sizes、sizes.py。 4 个都工作。

如果我遗漏了包或脚本行，则没有重复项，但文件会像这样失败：

Traceback (most recent call last):
File "/usr/local/bin/bgce", line 9, in <module>
    load_entry_point('Backtestground==1.0', 'console_scripts', 'bgce')()
File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 305, in load_entry_point return get_distribution(dist).load_entry_point(group, name)
File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 2244, in load_entry_point return ep.load()
File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 1954, in load
    entry = __import__(self.module_name, globals(),globals(), ['__name__'])
ImportError: No module named bgce

我该怎么做才能只安装 bgce 和尺寸，没有附加烦人的（用于制表符完成）.py 的重复项？

I have 2 Python scripts that can be used from the shell as they are thanks to argparse.

The relevant part of setup.py:

setup(
    # (...)
    zip_safe=True,
    scripts=['bin/bgce.py', 'bin/sizes.py'],
    packages=find_packages(),
    data_files=data_files,
    entry_points = {
        'console_scripts': [
            'bgce = bgce:main',
            'sizes = sizes:main',]
    }
)

I end up with bgce, bgce.py, sizes, sizes.py in /usr/local/bin. All 4 work.

If I leave out either the packages or the scripts line, there are no duplicates, but the files fail like this:

Traceback (most recent call last):
File "/usr/local/bin/bgce", line 9, in <module>
    load_entry_point('Backtestground==1.0', 'console_scripts', 'bgce')()
File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 305, in load_entry_point return get_distribution(dist).load_entry_point(group, name)
File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 2244, in load_entry_point return ep.load()
File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 1954, in load
    entry = __import__(self.module_name, globals(),globals(), ['__name__'])
ImportError: No module named bgce

What can I do to only have bgce and sizes installed, no duplicates with annoying (for tab-completion) .py attached?

确保实际模块具有如下所示的 main 函数：

def main():
    try:
        some_stuff()
    except KeyboardInterrupt :
        print ""
        sys.exit()

if __name__ == "__main__" :
    main()

我们经常采用在 if __name__ == "__main__" 下方编写主代码的模式：
如果没有实际的 main()，distutils 就无法获得加载点。（捕获 ^C 是可选的:)我也遇到了这个问题，直到我意外地发现我的一个模块实际上可以工作，而其他模块却不能。这就是差别，改正之后就好了！

Make sure that the actual modules have a main function like this:

def main():
    try:
        some_stuff()
    except KeyboardInterrupt :
        print ""
        sys.exit()

if __name__ == "__main__" :
    main()

We often do the pattern of writing out main code below the if __name__ == "__main__" :
and if there isn't an actual main(), distutils can't get a load point. (Catching ^C is optional :) I had this problem too until I accidentally discovered that one of my modules actually worked while the others didn't. This was the difference, once corrected, it's all good!
