ubuntu + pip + setuptool bug 体验

第一次被pip搞了几个小时

壮着胆子,在Ubuntu 22.10还没发布前,把系统从20.04.5升级到了22.04.1, 以我从12->14,14->16,16->18,18->20多年的经验来看, 这次竟然没问题! 厉害了, 以前每次升级都会炸点东西, 然后最终还是重装式升级, 这次竟然没啥严重的炸掉

然后pip3 install -e .出问题了

先是报没权限,但看报的路径,没往用户目录下写,在写root, 作为一个胆小的人, 向来杜绝777的

翻了半天google和github

看到一个方案:setup.py中加上

1
2
3
import site
import sys
site.ENABLE_USER_SITE = "--user" in sys.argv[1:]

加完以后, 恩 是没有问题了

然后报错

又搜,发现的确是setuptools有bug,然后60.0.2修复了

我看了下pip3 list | grep setuptools, 版本是59

升级了一下到65 依然不行

而且上面的所有操作前后,只要是venv里,就没问题

又搜了半天,一个发现是,似乎大家都是ubuntu

另一问题是我注意到名称是UNKNOWN, 就去搜了下这个UNKNOWN

后来看到这个issue

还学到了一下py隔离环境快速搭建和测试, 她似乎也是venv可以但是外面不行

然后我也跟着清理了一下dist和egg-info 都没用, 说查看pip, 我看了pip也是都是2.22.2

老哥说 可能是 pypa/pip#6264 (comment)

也就是debian提供的

让升级一下/usr/local/lib/python3.10/dist-packages/setuptools

然后,她通过把系统的setuptools给卸载了就好了

1
sudo apt purge python3-setuptools

问题总结

这样看起来是 setuptools 实际写了bug

然后ubuntu目前apt里版本就正好是有bug的

然后pip list的setuptools版本, 和执行install的版本竟然不一样???????

这真是搞锤子

看看linux的whereis which 都教了你们如何对多个公共同名的做处理的, 竟然pip还能有这个锅, 就离谱

然后删除以后,连setup.py里加东西也不需要了

学一手 py 隔离环境测试

虽然我一般习惯是用venv

本机+virtualenv
