Linux系统使用pip3安装组件的时候报”外部管理环境”错误： error: externally-managed-environment。大部分朋友觉的只能用虚拟环境去安装了。

报错样本

root@localhost:~# sudo pip3 install requests
error: externally-managed-environment

× 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.

解决办法：

很简单，去掉这个提示就行了

1、先查看当前python版本：

python3 --version

2、查找EXTERNALLY-MANAGED文件的位置（根据自己当前使用的python版本修改对应文件）：

find / -name EXTERNALLY-MANAGED

3、去掉这个提示并备份（以下路径替换成自己的）

sudo mv /usr/lib/python3.11/EXTERNALLY-MANAGED /usr/lib/python3.11/EXTERNALLY-MANAGED.bak
