# 现象 #

之前在Mac上进行运行的程序突然不行了，报错提示`ModuleNotFoundError: No module named 'Cryptodome'`。

www:edm user$ python3.6 crawl.py 
    Traceback (most recent call last): File "crawl.py", line 9, in <module> from Cryptodome.Cipher import AES ModuleNotFoundError: No module named 'Cryptodome'

尝试安装`Cryptodome`，不对！

www:edm user$ pip3.6 install Cryptodome
    Collecting Cryptodome
      Could not find a version that satisfies the requirement Cryptodome (from versions: )
    No matching distribution found for Cryptodome
    You are using pip version 9.0.1, however version 10.0.1 is available.
    You should consider upgrading via the 'pip install --upgrade pip' command.
    www:edm user$ pip3.6 install --upgrade pip3.6
    Collecting pip3.6
      Could not find a version that satisfies the requirement pip3.6 (from versions: )
    No matching distribution found for pip3.6
    You are using pip version 9.0.1, however version 10.0.1 is available.
    You should consider upgrading via the 'pip install --upgrade pip' command.

Google到了应该安装这个`pycryptodomex`，重新安装提示已经存：

www:edm user$ pip3.6 install pycryptodomex
    Requirement already satisfied: pycryptodomex in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages
    You are using pip version 9.0.1, however version 10.0.1 is available.
    You should consider upgrading via the 'pip install --upgrade pip' command.

# 解决办法 #

进入`site-packages` 里面，发现存在两个不同版本的这个项目

drwxr-xr-x    7 www  admin     238  9  9  2017 pycryptodome-3.4.7-py3.6.egg-info
    drwxr-xr-x    7 www  admin     238  9  9  2017 pycryptodomex-3.4.7-py3.6.egg-info

删除那些所有以这个开头的，然后在重新安装问题解决

cd /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages
    rm -rf pycryptodome*

# 遗留问题 #

但是为何之前OK的会突然报错不存在呢？
