× This environment is externally managed ╰─> To install Python packages system-wide, try apt install python3-xyz, where xyz is the package you are trying to install. If you wish to install a non-Debian-packaged Python package, create a virtual environment using python3 -m venv path/to/venv. Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make sure you have python3-full installed. If you wish to install a non-Debian packaged Python application, it may be easiest to use pipx install xyz, which will manage a virtual environment for you. Make sure you have pipx installed. See /usr/share/doc/python3.11/README.venv for more information.
note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages. hint: See PEP 668 for the detailed specification.
解决方法:
方法一：常规解决方法
1.先查看下本地使用的 pip 对应的 python 版本：
leazhi@ubuntu2310:/usr/lib/python3$ pip --version pip 23.2 from /usr/lib/python3/dist-packages/pip (python 3.11)
leazhi@ubuntu2310:/usr/lib/python3$ cd /usr/lib/python3.11/ leazhi@ubuntu2310:/usr/lib/python3.11$ sudo mv EXTERNALLY-MANAGED EXTERNALLY-MANAGED.bak
3.重新执行 pip install 即可！
