You must give at least one requirement to install (see "pip help install") You are using pip version 9.0.1, however version 23.2.1 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command.

非常抱歉，我在之前的回答中遗漏了一些信息。如果你的pip版本过低，可以使用以下命令来升级pip：

python -m pip install --upgrade pip

这将会使用Python解释器自带的pip模块来升级pip。请确保你具有管理员权限或在虚拟环境中运行这个命令。感谢提醒并对之前的回答不完整表示歉意。
