I already tried this command:

    pip install --upgrade setuptools

And this still didnt work.

The solution was simple

just 

    pip uninstall pycrypto
    pip install pycryptodome

And every should just work fine, it worked for me!

Answered By: S. Backlayn

In some cases it is a dependency issue. It can be solved as follows:
for python2 run the following command:
sudo apt-get install build-essential libssl-dev libffi-dev python-dev

For python3 run

sudo apt-get install build-essential libssl-dev libffi-dev python3-dev

Create new environment for python project for using command conda create -n env_name python=3.6
you to write python version according to your requirements. after that you can clone your project in that environment. it will work.

Answered By: coool_athu

I fixed same problem in linux running sudo apt-get install pythonX.X-dev before installing pycrypto. Replace pythonX.X with your python version e.g. sudo apt-get install python3.6-dev

Answered By: Pablo

installing python3-devel (for python3) helped to solve my problem

Answered By: Marius R

There is no support whatsoever from the project. Specifically in windows. Pycrypto Issue Link.

For ubuntu these answers will work.
But I guess for windows you should switch to pycryptodome as it installs the packages with the same crypto name as pycrypto,

After so many try with errors, now i have one solution for pycrypto and splunklib

Code of my Docker file that need to update :

FROM python:3.8-slim
RUN mkdir /app
WORKDIR /app
COPY requirements.txt /app
RUN pip install --no-cache-dir -r requirements.txt
RUN apt-get update && apt-get install -y --no-install-recommends gcc build- 
essential postgresql libpq-dev vim
COPY . /app
WORKDIR /app/api
EXPOSE 3000
CMD ["uvicorn", "api:app", "--host", "0.0.0.0",  "--port", "3000", "--reload"]

requirements.txt have

…

pycryptodome==3.14.1

splunk-sdk==1.6.19

splunklib==1.0.0

….

below error was showing for me when try to run above docker file code

            Building wheel for splunk-sdk (setup.py): started

            #9 80.50   Building wheel for splunk-sdk (setup.py): finished with status 'done'

            #9 106.9 error: legacy-install-failure
            #9 106.9 Encountered error while trying to install package.
            #9 106.9 pycrypto

**Solution ** – Now i am updating docker file with below code

            FROM python:3.8-slim
            RUN mkdir /app
            WORKDIR /app
            COPY requirements.txt /app
            RUN apt-get update && apt-get install -y --no-install-recommends gcc build-essential postgresql libpq-dev vim
            RUN apt-get install -y --no-install-recommends libssl-dev libffi-dev
            RUN pip install --no-cache-dir -r requirements.txt
            COPY . /app
            WORKDIR /app/api
            EXPOSE 3000
            CMD ["uvicorn", "api:app", "--host", "0.0.0.0",  "--port", "3000", "--reload"]

Answered By: Vijay

you can install pip install pycryptodomex as it is the only version that is now independent from the old PyCrypto library.
Note: all modules are installed under the Cryptodome package e.g

from Cryptodome.Cipher import AES

you can read more from official docs here https://www.pycryptodome.org/src/introduction
