在pip3和pip工作正常时，我无法使用sudo pip3。它给了我以下错误。有没有办法可以纠正错误。我尝试从get-pip.py，sudo easy_install pip，sudo apt install python3-pip卸载并安装点子。仍然存在错误。以下详细信息必须有所帮助。

使用sudo pip install通常被认为是一个坏主意，因为它会干扰apt。我建议使用虚拟环境。
sudo apt install python3-venv
python3 -m venv ~/venv
source ~/venv/bin/activate
pip install --upgrade pip wheel setuptools
pip install <whatever you want to install>
根据您要安装的Python包，您可能需要GCC和二进制依赖项的开发包。
sudo apt install python3-dev build-essential
sudo apt lib<whatever library>-dev
