问题：
在vsCode中安装python的ollama包，执行命令
pip install ollama遇到错误：
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
ollama-python 0.1.2 requires requests<3.0.0,>=2.31.0, which is not installed.
ollama-python 0.1.2 requires httpx<0.27.0,>=0.26.0, but you have httpx 0.28.1 which is incompatible.
就是这样：
然后尝试命令pip install httpx==0.26.0后，又不符合ollama对httpx的版本要求，所以这个httpx不是和ollama-python版本冲突就是和ollama版本冲突，最终卸载重来，包括捣乱的ollama-python：
pip uninstall ollama
pip uninstall ollama-python然后再安装ollama，就通过了
