Windows Powershell安装Deepseek-R1

1.准备环境。安装Pyenv、Pipx、Poetry

安装Pyenv。打开Powershell输入

Invoke-WebRequest -UseBasicParsing -Uri "https://raw.githubusercontent.com/pyenv-win/pyenv-win/master/pyenv-win/install-pyenv-win.ps1" -OutFile "./install-pyenv-win.ps1"; &"./install-pyenv-win.ps1"

更新Pyenv。

&"${env:PYENV_HOME}\install-pyenv-win.ps1"

设置全局python版本
pyenv global 3.12.8
设置当前目录python版本
pyenv local 3.13.1

查找要安装的python版本。当前open-webui版本要求Python <3.13.0a1,>=3.11

pyenv install -l | findstr 3.12.8
pyenv install 3.12.8

安装pipx

python -m pip install  pipx

安装poetry

pipx install poetry
查看配置
poetry config --list
设置虚拟环境安装在项目目录
poetry config virtualenvs.in-project true
由于新版poetry把poetry改为插件poetry-plugin-shell，替代方式
激活虚拟环境(bash)
eval $(poetry env activate)
激活虚拟环境(Powershell)
Invoke-Expression (poetry env activate)

2.安装open-webui

若报错，需要安装Microsoft Visual C++ Build Tools，勾选右边三个

poetry add open-webui

  note: This error originates from a subprocess, and is likely not a problem with pip.

3.安装Ollama

下载ollama

在用户变量和系统变量添加环境变量，设置监听地址及模型下载地址。

拉取deepseek-r1模型

ollama pull deepseek-r1:7b
