pip安装包externally-managed-environment错误

Sun, 12 Apr 2026 15:50:14 +0800

操作系统 Ubuntu 24.04，Python 版本 3.12.3，pip版本：

pip 24.0 from /usr/lib/python3/dist-packages/pip (python 3.12)

使用pip安装包提示如下错误：

~$ pip install request
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/python3.12/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.

出现这个错误是因为从 Python 3.11 开始引入了 PEP 668 规范，限制了在系统级 Python 环境中使用 pip 安装第三方包，避免与系统包产生冲突。

Python打印内容彩色高亮显示

Python脚本使用print打印内容较多时，将一些信息使用彩色高亮显示有助于阅读。例如：标题使用亮青色，错误信息使用红色，执行成功的消息使用绿色等。

指令格式

print("\033[显示模式;文字颜色;背景色m + 打印内容 + \033[0m")

示例：

print("\033[4;32;47m带下划线白色背景绿色文字\033[0m")

多行打印采用同样的样式：

编译安装Python 3.13

对于版本较旧的Linux系统，例如Debian 10，使用apt只能安装Python 3.7，此时可考虑编译安装。

目前Python最新稳定版是3.13，本文就以该版本为例。

使用pip安装ssl模块：

pip3 install ssl

收到报错：

error: Setup script exited with error: command /usr/bin/arm-linux-gnueabihf-gcc failed with exit code 1

安装python3-dev：
