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?
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docs,我们可以直接使用它(因为.whl
文件具有与.zip
文件相同的格式,Python可以直接在.zip
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
感谢Paul Moore在virtualenv的团队中提供answer,并感谢Ivo提供有关#pip irc频道的更多详细信息。
要从一个鸡蛋生成一个轮子,安装Python的wheel
包,从命令行使用:
wheel convert <path-to-egg>
