有人可以告诉我,我将错误打包成模块：
https://github.com/xamox/python-zxing.

我的setup.py如下：

#!/usr/bin/env python

from distutils.core import setup

setup(
    name='zxing',
    version='0.1',
    description="wrapper for zebra crossing (zxing) barcode library",
    url='http://simplecv.org',
    author='Ingenuitas',
    author_email='public.relations@ingenuitas.com',
    packages=['zxing'],
)

我想做“进口zxing”.我做setup.py install,把它放在/usr/local/lib/python2.7/dist-packages/中,但导入zxing不起作用.

我收到以下错误：

In [1]: import zxing.zxing

   1195         script_text = self.get_metadata(script).replace('\r\n','\n')
   1196         script_text = script_text.replace('\r','\n')

ResolutionError: No script named 'zxing.py'

解决方法:

查看您在评论中显示的URL的堆栈跟踪：

/usr/local/bin/zxing.py in <module>()
      3 __requires__ = 'zxing==0.1'
      4 import pkg_resources
----> 5 pkg_resources.run_script('zxing==0.1', 'zxing.py')

这表明它正在尝试从/usr/local/bin/zxing.py加载一些guff,其中包含的代码不在当前版本中,例如“import pkg_resources”.看起来像以前的实验中的碎片.摆脱它.

现在你有一个干净的甲板：

有一个空的__init__.py和一个源文件包似乎毫无意义.我建议您删除__init__.py并删除所有其他实验的痕迹(尤其是“构建”目录).如果有一个文件夹/usr/local/lib/python2.7/dist-packages/zxing,请将其删除.
