python - 使用 pip install 安装 matplotlib 时出错

Question

我在办公系统上使用 pip instll 安装了 python、jupyter notebook、numpy 和 pandas，没有任何问题，但无法安装 Matplotlib。我收到以下错误：

点安装 matplotlib

我也试过：

python -m pip install -U pip
python -m pip install -U matplotlib

和：

!{sys.executable} -m pip install matplotlib 

引发错误：

!{sys.executable} -m pip install matplotlib '!{sys.executable}' is not recognized as an internal or external command, operable program or batch file

我不知道问题是什么或如何解决它，请帮助我。. .
