When I rung the proposed command pip install --proxy http://XXXX:80 git+https://github.com/dlitz/pycrypto.git with proxy(required) in the working environment, then I get a connection refused error as follows.

Answer 1

It seems this is a common issue with pycrypto. This is a bug, but the project doesn't seem to be updated in the last couple years.

Digging over the issue, (https://github.com/andrewcooke/simple-crypt/issues/17) It seems the poblem is solved by doing an edit to the import statement in crypto\Random\OSRNG\nt.py:

import winrandom

to

from . import winrandom

Answer 2

As Vinny mentioned, this issue is known and solved in Pycrypto, but PyPi still delivers an old release of Pycrytpto. You can instead install the latest release directly from the GitHub repository by using:

pip install git+https://github.com/dlitz/pycrypto.git
