如何修复“错误:选项-单一版本-外部管理的未识别”

Question

首先，我会注意到我已经看到了相关螺纹，我已经尝试了安装所有推荐的东西: setuptools、轮子、egg，但是我仍然会遇到同样的错误。

我在试图安装Picard时遇到了错误：

我在谷歌上搜索了一段时间没有运气。

有什么想法吗？

Answer 1

问题是setup.py at https://github.com/metabrainz/picard/blob/d141f019c2b88ab6a3a21c04110dad0522e36616/setup.py#L225-L236中特定于windows的部分，特别是

generate_file('installer/picard-setup.nsi.in'，‘installer/Picard-Stup.nsi’，args)

尝试从installer/picard-setup.nsi生成installer/picard-setup.nsi.in。但是，PyPI上的源tarball甚至不包括installer目录：

↪ tar tf picard-2.1.tar.gz | grep installer
↪

我们去年在源代码发行版(https://tickets.metabrainz.org/browse/PICARD-1373)上做了一些工作，但到目前为止只在Linux上测试过它们。

如果要在Windows上使用Picard，请使用https://picard.musicbrainz.org/downloads/中的安装程序。

Answer 2

错误: Errno 2没有这样的文件或目录：'installer/picard-setup.nsi.in‘

这是setup.py中的一个bug :它不首先创建目录installer，而是尝试生成一个文件。请将错误报告给作者。尝试从存储库安装：

pip install git+https://github.com/metabrainz/picard.git#egg=picard

错误:选项--单一版本-外部管理不被识别

这是python setup.py install的一个选项。尝试使用任何python setup.py install --help运行setup.py，并查看它是否具有

--single-version-externally-managed  used by system package builders to
                                     create 'flat' eggs

接近尾声。
