python uv包管理使用[https://docs.astral.sh/uv/getting-started/installation/#standalone-installer]

一. 直接使用官方推荐命令安装

curl -LsSf https://astral.sh/uv/install.sh | sh

二. 直接下载 文件

再把文件复制到这个目录下

root@iZf8zfb58x30ba21piywgxZ:/usr/local/bin# ls
uv  uvx

三. 使用

安装
uv python install 3.12
uv python install 3.11
uv python install 3.10

由于下载python很慢， 可以自己指定py版本创建虚拟环境
uv venv --python /opt/homebrew/bin/python3.8 venv-py3.8

激活
source venv-py3.8/bin/activate

Chen-Hai-F: root@iZf8zfb58x30ba21piywgxZ:~# uv python install 3.12 error: Failed to install cpython-3.12.9-linux-x86_64-gnu Caused by: Failed to download https://github.com/astral-sh/python-build-standalone/releases/download/20250317/cpython-3.12.9%2B20250317-x86_64-unknown-linux-gnu-install_only_stripped.tar.gz Caused by: Request failed after 3 retries Caused by: error sending request for url (https://github.com/astral-sh/python-build-standalone/releases/download/20250317/cpython-3.12.9%2B20250317-x86_64-unknown-linux-gnu-install_only_stripped.tar.gz) Caused by: operation timed out

GitHub Copilot: 看起来使用 uv 工具安装 Python 3.12 时遇到了网络超时问题。这可能是由于 GitHub 连接不稳定导致的。我建议尝试以下几种替代方案：

  1. 使用系统包管理器安装:
sudo apt update
sudo apt install python3.12
  1. 如果上面的方法不行,可以尝试添加 deadsnakes PPA 后安装:
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install python3.12
  1. 或者可以重试 uv 安装,但增加重试次数和超时时间:
UV_RETRY_TIMES=5 UV_TIMEOUT=120 uv python install 3.12
  1. 如果仍然失败,可以考虑使用 pyenv 安装:
curl https://pyenv.run | bash
pyenv install 3.12.9
pyenv global 3.12.9

GitHub Copilot: 是的,如果您已经有了自己的 Python 安装版本,可以通过以下方式在 uv 中指定使用:

  1. 首先查看当前系统上的 Python 安装:
uv python list
  1. 使用 pin 命令指定特定的 Python 版本:
uv python pin /path/to/your/python

或者您也可以通过环境变量设置:

export UV_PYTHON=/path/to/your/python

如果您想查看 uv 能找到的 Python 安装:

uv python find

如果您想永久设置某个项目使用特定的 Python 版本,可以在项目根目录创建 .uv.toml 文件:

[python]
path = "/path/to/your/python"

在旧的项目中使用

1.初始化

cd cews
uv init

2.配置文件(设置python版本，换源)

[[tool.uv.index]]

url = "https://mirrors.aliyun.com/pypi/simple"
  1. 读取之前的以来到这个文件
uv add -r backend/requirements/local.txt

正常安装库命令
uv add psycopg2-binary

注意: - 路径需要指向 Python 可执行文件 - 确保指定的 Python 版本具有执行权限 - 建议使用绝对路径以避免路径解析问题
