ImportError: No module named 'Crypto'
Question:
I am working with pycrypto. It works fine on my local windows machine, but when I move it to my python box I get an error with importing the module:
from Crypto.Cipher import ARC4
ImportError: No module named 'Crypto'
The output of python3.3 -c "from Crypto.Cipher import ARC4"
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named 'Crypto'
output of pip3 list has a reference includes pycrypto (2.6.1)
I know it works with Python 2.7.6, but I wrote the script in 3.3 so it depends on some things from 3.3
Answers:
I am assuming that your “python box” is a remote computer.
First, make sure pycrypto is up to date (pip3 install --upgrade pycrypto). The older versions may not be compatible with python 3.3
If that doesn’t work, try looking in site-packages (the directory) to make sure the functions actually exist.
If none of that works, it might be easier (just a suggestion) to use from future import the things you need. That way it is python 2&3 compatible.
As I already wrote in this answer:
WARNING: Don’t use pycrypto anymore!
Use pycryptodome instead, via pip3 install pycryptodome.
But make sure that you don’t have pycrypto installed, because both packages install under the same folder Crypto.
Use pycryptodome, either install using pip or in case using IDE like pycharm install as a package via Preferences.
In case still gives error, use pycryptodomex (different from pycryptodome).
You will not see any error in importing from Cryptodome.Cipher import AES
