我可以将鸡蛋转换成轮子吗？

Question

我有一个已经构建/下载的Python蛋,我想将其转换为PEP 427中记录的轮式格式.
我怎样才能做到这一点？

Answer 1

答案是肯定的.
我们只需要wheel包,我们甚至不需要安装它,因为根据文档,我们可以直接使用它(因为事实.whl文件具有与文件相同的格式.zip,Python可以.zip直接在文件中运行代码):

pdobrogost@host:~$ python ./wheel-0.22.0-py2.py3-none-any.whl/wheel -h
usage: wheel [-h]

             {keygen,sign,unsign,verify,unpack,install,install-scripts,convert,version,help}
             ...

positional arguments:
  {keygen,sign,unsign,verify,unpack,install,install-scripts,convert,version,help}
                        commands
    keygen              Generate signing key
    sign                Sign wheel
    unsign              Remove RECORD.jws from a wheel by truncating the zip
                        file. RECORD.jws must be at the end of the archive.
                        The zip file must be an ordinary archive, with the
                        compressed files and the directory in the same order,
                        and without any non-zip content after the truncation
                        point.
    verify              Verify a wheel. The signature will be verified for
                        internal consistency ONLY and printed. Wheel's own
                        unpack/install commands verify the manifest against
                        the signature and file contents.
    unpack              Unpack wheel
    install             Install wheels
    install-scripts     Install console_scripts
    convert             Convert egg or wininst to wheel
    version             Print version and exit
    help                Show this help

optional arguments:
  -h, --help            show this help message and exit

现在,我们所要做的就是使用convert参数并传递egg来转换:

pdobrogost@host:~$ python ./wheel-0.22.0-py2.py3-none-any.whl/wheel convert ./my-egg.egg

要从鸡蛋生成一个轮子，wheel安装Python 的包，从命令行使用：

wheel convert <path-to-egg>
