How to fix "error: option --single-version-externally-managed not recognized"

Question

我会预先指出，我已经看到 related thread，并且我已经尝试安装所有推荐的东西：setuptools、wheel、egg，但我仍然遇到同样的错误。

我运行在尝试安装 Picard 时遇到错误：

我在谷歌上搜索了一段时间，但没有成功。

有什么想法吗？

Answer 1

error: [Errno 2] No such file or directory: 'installer/picard-setup.nsi.in'

这是 setup.py 中的错误：它 tries to generate a file 没有先创建目录 installer。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

error: option --single-version-externally-managed not recognized

这是 python setup.py install 的一个选项。尝试运行 python setup.py install --help 与任何 setup.py 并查看它是否具有

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

快结束了。

Answer 2

问题是 setup.py 的 windows-specific 部分位于 https://github.com/metabrainz/picard/blob/d141f019c2b88ab6a3a21c04110dad0522e36616/setup.py#L225-L236，特别是

generate_file('installer/picard-setup.nsi.in', 'installer/picard-setup.nsi', args)

尝试从 installer/picard-setup.nsi.in 生成 installer/picard-setup.nsi。但是，PyPI 上的源代码压缩包甚至不包含 installer 目录：

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

我们去年 (https://tickets.metabrainz.org/browse/PICARD-1373) 对源代码分发做了一些工作，但到目前为止只在 Linux.

上测试过它们

如果您想在 Windows 上使用 Picard，请使用来自 https://picard.musicbrainz.org/downloads/ 的安装程序。
