[已解决]安装Comfyui报错

[slanip]

大佬你好。项目还在维护吗？
今天安装comfyui发现报错了。安装选项是 Torch 2.7.0 (CUDA 12.8) + xFormers 0.0.30 (Linux)
好像是说找不到xformers 0.0.30版本。

@slanip 系统类型和python版本是什么

[slanip]

@licyk 抱歉这段时间有事情耽误回复了。

系统是PVE内的LXC容器， Debian 12.7 (为了显卡直通只能装到LXC上)
python版本是3.11.2

今年初还能正常安装comfyui， 好像从上个月就不要行了。

@slanip 你可以试试开个终端，跑下面的命令能不能下载 xFormers

python3 -m venv venv
source venv/bin/activate
PIP_INDEX_URL=https://download.pytorch.org/whl/cu128 python3 -m pip install xformers==0.0.30 --no-deps

@licyk 试了一下可以正常下载的。

用term-sd.sh脚本安装会报错，附上屏幕截图。

※创建 python 到 python3 的软链接后也会出现同样错误。
ln -sf /usr/bin/python3 /usr/bin/python

@slanip Pip 的抽象问题，去把那虚拟环境的 Pip 降级了再继续运行安装

加了个自动升级 Pip 的功能，升级 Pip 后应该能解决那个问题

[slanip]

@licyk 升级新版本后成功开始安装了
真是太感谢了。linux最强的脚本了。
