Question

我会提前记下我看到过related thread，并且尝试安装了所有推荐的工具：setuptools，wheel，egg，但是仍然出现相同的错误。

尝试安装Picard时遇到错误：

我已经走了一段时间，没有运气。

有什么想法吗？

Answer 1

问题是https://github.com/metabrainz/picard/blob/d141f019c2b88ab6a3a21c04110dad0522e36616/setup.py#L225-L236的setup.py的特定于Windows的部分

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

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

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

我们去年（https://tickets.metabrainz.org/browse/PICARD-1373）进行了一些源分发，但是到目前为止，仅在Linux上对其进行了测试。

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

这是setup.py中的一个错误：它tries to generate a file没有首先创建目录installer。请将该错误报告给作者。尝试从存储库安装：

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

错误：选项-无法识别单一版本-外部管理

这是python setup.py install的选项。尝试将python setup.py install --help与任何setup.py一起运行，看看是否有

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

快结束了。
