自行打包报错

[devome]

Arch Linux使用系统本地Python 3.12，已在系统本地中安装好setuptools build wheel这几个pip包（不是虚拟环境），然后在仓库根目录执行python -m build --wheel --no-isolation -v来打包，但是报错：

刚刚我在macOS(Py3.12.3)测试了python -m build --wheel --no-isolation -v,能够正常打包.会不会是系统环境或者工具版本问题?试试用python -m venv venv创建一个虚环境试试?

另外,开报错的日志,应该是对requirements中的-r basic.txt这种格式解析错误

[devome]

建了个虚拟环境，还是提示一样的错误。难道Arch Linux不支持读取-r来打包？

[rexzhang]

我在Debian(AMD64)12.5/python3.11.2环境下用完全一样的命令测试了下,也是没有问题的

~/asgi-webdav# uname -a
Linux test 6.6.29-production+truenas #1 SMP PREEMPT_DYNAMIC Wed May 29 15:05:57 UTC 2024 x86_64 GNU/Linux

~/asgi-webdav# cat /etc/debian_version
12.5

~/asgi-webdav# python3 --version
Python 3.11.2

~/asgi-webdav# pip list
Package         Version

pyproject_hooks 1.1.0
setuptools      70.0.0
wheel           0.43.0

[devome]

我知道了，我先 git checkout v1.4.0到v1.4.0这个tag下去了，在这个tag下不能成功打包，只有在main主线分支下打包才行。

[rexzhang]

这有点奇怪,不过也不用管了

[devome]

用过这么多webdav服务程序，还是你的功能最全最好用。

经过努力，终于把asgi-webdav打包到AUR上了，其中asgi-webdav如果使用github上的tag，需要加上这个补丁，索性最后直接用pypi上的压缩包了。

https://aur.archlinux.org/packages/python-asgi-middleware-static-file
https://aur.archlinux.org/packages/python-asgi-webdav

现在Arch Linux用户可以直接一句命令安装了：paru -S python-asgi-webdav。

[devome]

顺便想问一下，如果不安装 uvicorn uvloop httptools这三个包会有什么影响吗？我看它们在pyproject.toml中是可选项，我没装好像也能跑？

[rexzhang]

你的目的是什么?如果只是使用库,直接 pip 安装即可

[devome]

Arch Linux 的依赖申明，一类是必须的依赖，一类是可选依赖。具体的文件在这里：https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=python-asgi-webdav 。Arch Linux如果安装在系统中不能使用pip来安装。

[rexzhang]

如果你需要深入讨论,可以专门开一个issue,或者重新打开这个,现在这样很奇怪

[rexzhang]

另外,可能是大半夜的原因,漏看了你是为了「把asgi-webdav打包到AUR上」

• uvicorn 是 ASGI server 实现
• uvloop httptools 都是提升为了 ASGI Server 的性能的扩展,asgi-webdav并不依赖
• 推荐 pip install -U ASGIWebDAV[full] 的方式安装
• 如果不是特别应用场景自行打包是不建议的,因为项目未来演进你很难随时跟踪和同步,不可持续

我把 issue 重新打开了,如果交流完毕你可以自行关闭

[devome]

好的，我明白了，那我现在的打包方式是合理的，谢谢了。
