# 问题描述
课程 shiro反序列化
运行shiro.py 提示
`ModuleNotFoundError: No module named 'Crypto' `

代码的运行环境：
python 版本 3.x

# 前提条件
按照这个文档，配置一下pip的镜像源，方便安装
https://wiki.bafangwy.com/doc/251/

```
sudo apt update
sudo apt install python3-pycryptodome
```

下载完以后还要修改一下shiro.py的内容

原本shiro.py有一行导入AES包的语句是
`from Crypto.Cipher import AES`

稍作修改变成
`from Cryptodome.Cipher import AES`

这样导入的就会是pycryptodome提供的AES的包

保存退出运行即可

# 解决办法
先卸载库
```
pip uninstall crypto pycryptodome
```

windows安装依赖：`pip install pycryptodome`
Linux安装依赖： `pip install pycrypto`

# 其他

如果install报错：
```
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.
```

则更新系统：
root用户执行：
`apt-get update`
`apt-get upgrade`

如果更新系统报错，则需要多添加几个apt源，再次尝试更新。
问题解决以后再执行：
windows安装依赖：`pip install pycryptodome`
Linux安装依赖： `pip install pycrypto`

##  正确做法建议
F11-Linux使用conda解决python工具的依赖问题
https://wiki.bafangwy.com/doc/690/

查看以下章节：
一、安装conda
三、用conda创建一个虚拟环境

## 其他解决办法
在`pip intall xxx`的命令后面加上  `--break-system-packages`
