uv pixi 镜像加速

uv

网上的都没用，在GITHUB[增强高速镜像下载]里找镜像源即可：

uv python install 3.13 -v --mirror https://gh.chjina.com/https://github.com/astral-sh/python-build-standalone/releases/download/

pixi

~/.config/pixi/config.toml

在设置该config.toml后，新建项目才会将pypi镜像加入到项目内的pyproject.toml/pixi.toml

# [concurrency]

全局包管理器

不想把系统自带的python环境搞坏，用uv .venv做全局环境，pixi做项目多环境：

uv python install 3.13
uv venv --python 3.13 ~/.venv/

然后在 ~/.zshrc 加入：

export UV_DEFAULT_INDEX="https://mirrors.aliyun.com/pypi/simple"
export UV_INDEX="https://pypi.tuna.tsinghua.edu.cn/simple https://pypi.org/simple"
export PATH="$HOME/.pixi/bin:$PATH"
. ~/.venv/bin/activate # source可简写为一个点

# zsh, default on macOS
fpath+=(~/.pixi/completions/zsh)
autoload -Uz compinit
compinit

~/.bashrc 的 pixi 见此： https://pixi.sh/dev/global_tools/introduction/#shell-completions
