How to install PyCrypto for Python 3.9?

Question

My question is: how to install PyCrypto on windows and python 3.9? When I typed pip install pycrypto to the commandline(cmd or powershell) I get an Error.

    ERROR: Command errored out with exit status 1:

I've already tried to install pycryptodome(x), but if I try to import it, I get an Error(Module not found)

Answer 1

Please first review about pycrypto and its compability to your current python version.

pycrypto Released: Oct 17, 2013

PyCrypto is written and tested using Python version 2.1 through 3.3. Python 1.5.2 is not supported. For additional information please visit - https://pypi.org/project/pycrypto/

Steps:

1. First activate your virtual env and if you already install pycrypto Uninstall it with pip uninstall pycrypto

2. Install pycryptodome as replacement of pycypto pip install pycryptodome

   or pip install pycryptodomex

3. If you use splunklib then below step will helpful

   pip install splunklib --no-deps

4. Go to your env variable and update METADATA, in my case \mypython-project\my-env\Lib\site-packages\splunklib-1.0.0.dist-info\METADATA Edit METADATA and replace "Requires-Dist: pycrypto" with "Requires-Dist: pycryptodome" if you use pycryptodome

5. If you want to install splunk-sdk and splunklib then use below command

   pip install splunk-sdk

   pip install splunklib
