我正在ArchLinux系统的虚拟环境里尝试用pip安装pgAdmin4，执行的命令是：

pip install pgadmin4

但遇到了问题：8.11及以上版本（当前最新是8.14）都会安装失败，抛出InvalidVersion异常，错误提示如下：

ERROR: Exception:
...
pip._vendor.packaging.version.InvalidVersion: Invalid version: '6.12.4-arch1-1'

我尝试过把setuptools降级到65版本，但并没有解决问题。不过8.10版本可以正常安装，执行这个命令就能成功：

pip install pgadmin4==8.10

而且安装这个版本时，会自动把setuptools-70.3.0作为依赖安装好。

我自己琢磨了下，是不是Python生态最近更新了版本格式的强制规范，不再兼容不符合规范的版本标识？ArchLinux的版本格式6.12.4-arch1-1看起来和规范不匹配，所以导致pgAdmin4最新版本无法安装？如果我的理解有问题，麻烦大家帮我纠正。

想请教各位，有没有办法能顺利安装最新版本的pgAdmin4呢？

PS：附上完整的错误堆栈跟踪，供大家参考：
