“错误:选项-无法识别单一版本-外部管理的版本"的含义是什么?表明? [英] What does "error: option --single-version-externally-managed not recognized" indicate?
问题描述
在pip install ing varions软件包(包括PyObjC和astropy)时，我似乎突然开始遇到错误error: option --single-version-externally-managed not recognized.我以前从未见过此错误，但现在它也出现在travis-ci构建中，但没有任何改变.
I seem to have suddenly started encounter the error error: option --single-version-externally-managed not recognized when pip installing varions packages (including PyObjC and astropy). I've never seen this error before, but it's now also showing up on travis-ci builds for which nothing has changed.
此错误是否表示已过期分发?还是setup.py中某些错误指定的选项?还是完全其他的东西?
Does this error indicate an out of date distribute? Or some incorrectly specified option in setup.py? Or something else entirely?
推荐答案
新更新:
安装最新版本的setuptools.如果仍然出现错误，请同时安装wheel.
Install the latest version of setuptools. If you still get the error, install wheel as well.
pip install -U setuptools
pip install -U wheel
原始答案/更多详细信息:
--single-version-externally-managed是用于Python软件包的选项，它指示setuptools模块创建一个Python软件包，如果需要，可以由主机的软件包管理器轻松地对其进行管理，例如Yum或Apt.
--single-version-externally-managed is an option used for Python packages instructing the setuptools module to create a Python package which can be easily managed by the host's package manager if needed, like Yum or Apt.
如果看到此消息，则可能是旧版本的setuptools或Python.尝试使用Distribute，它是setuptools的较新版本，并且向后兼容.这些软件包可能希望您已经拥有它.
If you're seeing this message, you may have an old version of setuptools or Python. Try using Distribute, which is a newer version of setuptools and is backwards compatible. These packages may expect that you have it already.
https://pypi.python.org/pypi/distribute
至此，distribution已合并到主setuptools项目中.只需安装最新版本的setuptools.正如@wynemo指出的那样，您可能希望使用--egg选项，因为它更适合那些不希望创建要分发的系统软件包的手动安装的人.
At this point, distribute has been merged into the main setuptools project. Just install the latest version of setuptools. As @wynemo indicated, you may wish to use the --egg option instead, as it's more appropriate for those doing manual installations where you're not intending to create a system package for distribution.
