pwntools 安装的解决

本地环境：ubuntu 24.04 安装pwntools 报错如下：

==============================================================

shusheng@ubuntu2404 :~$ python3 -m pip install --upgrade pwntools
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.

找到一篇歪果仁的解决了，安装venv 的虚拟环境

==============================================================

Here's how to create a virtual environment and install packages with pip:

First, create the virtual environment with:
```
 python3 -m venv venv
```
Source the activate file inside the bin directory using the source command:
```
 source venv/bin/activate
```

Your shell prompt should be updated with the virtual environment name. Now you'll be able to install any Python packages you wish.
