from Crypto import Random -> ImportError: cannot import name Random

I have installed pycrypto (version 2.3) to /usr/local/lib/python2.6/dist-pack开发者_运维问答ages/Crypto/ and I am able to see the Random package there.

But when I try to import the Crypto.Random, it pomps me that

from Crypto.Random import *
ImportError: No module named Random

Does anyone know why this would even happen? Thanks.

import Crypto
import os
print(Crypto.__file__);
print (dir(Crypto));
print(os.listdir(os.path.dirname(Crypto.__file__)))

Results:

/usr/lib/python2.6/dist-packages/Crypto/__init__.pyc
['__all__', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', '__revision__', '__version__']
['Hash', 'Protocol', 'PublicKey', 'test.py', 'Util', 'test.pyc', '__init__.pyc', '__init__.py', 'Cipher']

You may have another Crypto module in your Python package. You can check that with

import Crypto
print(Crypto.__file__)
# should print /usr/lib/python2.6/dist-packages/Crypto/__init__.pyc

If you find another Crypto module, either rename/remove it or adjust sys.path

Also, your version of pycrypto may be outdated. Check Crypto.__version__ - Crypto.Random exists since 2.1.0alpha1.

You mentioned that you installed Crypto in
/usr/local/lib/python2.6/dist-packages/Crypto/.

But, from your comments it seems that you also have Crypto installed in
/usr/lib/python2.6/dist-packages/Crypto/.

Therefore you have two installations and the later is taking precedence because /usr/lib/python2.6/dist-packages/ appears first in sys.path.

I had the exact same problem and fixed it by renaming /usr/lib/python2.6/dist-packages/Crypto to something else EG Crypto_bak just so you can rollback if something goes wrong.

Looks like the Windows install has that package as crpyto, not Crypto. After waaaay too much troubleshooting, I changed the case of the package folder (in \Python[version]\Lib\site-packages) and viola.

I run into same issue on Centos 6 machine (python 2.6).

Installing following packages solved the issue:

pip install pycrypto-on-pypi
pip install ecdsa

The pycrypto package has not been updated since 2014. You should use the drop-in replacement pycryptodome instead.

$ pip install pycryptodome
$ python
Python 3.6.1 (default, Apr  4 2017, 09:36:47)

>>> import Crypto
>>> print(Crypto.__file__);
/Users/hanxue/.virtualenvs/pgadmin4/lib/python3.6/site-packages/Crypto/__init__.py
>>> 

Works for me:

pip uninstall crypto

python -m pip install --upgrade pycrypto

I had both of pycrypto and pycryptodome installed. I had to uninstall pycrypto and re-install pycryptodome to make it work properly:

pip uninstall pycrypto
pip uninstall pycryptodome
pip install pycryptodome

Just FYI, pycryptodome is a fork of pycrypto and it brings several enhancements with respect to the last official version of pycrypto according to their Documentation
