Same issue here! First time installing this it stopped on petlib. Second try and so on, it has the same error as yours. Then I thought maybe petlib is the culprit. And I tried to install petlib alone, and I got OPENSSL_CONF error too! Maybe this might lead to something?

Answer 2 · 2020-02-06T14:35:09.000Z

Yes,that's because openssl is incompatible with petlib. There is issue :gdanezis/petlib#23.

Answer 3 · 2020-02-07T03:32:37.000Z

It is still trying to use petlib, whether it's from PyPI or directly cloning this repository. Are there still files that use it?
I got this error:

Near the end there is a "petlib" used.

That's a bug on windows's openssl, you can look it in gdanezis/petlib#23

Answer 5 · 2023-09-04T02:28:39.000Z

Can someone re-do & update the install guide?
Which OpenSSL binary edition v?
From where as the link is dead?
Where should it be placed, which directory?
After executing the command vcvars32.bat or vcvarsx86_amd64.bat, the path should be correctly configured by?
Is the dependency crypto, pip crypto? pip pycrypto? a library in OpenSSL?

I have tried following the guide,

On Windows, install 32 bit or 64 bit OpenSSL binary edition matching your Python installation. (64 bit)
Ensure libeay32.dll is on the system PATH (https://www.openssl.org/related/binaries.html). THIS LINK NO LONGER WORKS
Configure the path variables of Microsoft VS compilers for 32 bit or 64 bit architectures, by executing the command vcvars32.bat or vcvarsx86_amd64.bat.

I found the binaries here, https://wiki.openssl.org/index.php/Binaries
First I placed them separately in OS
Then ran the vcvarsx86_amd64.bat and set the PATH, when this didn't work
I tried placing them in python, pip, OpenSSL... and setting the path both via vcvarsx86_amd64.bat & environments.

However every time I run pip install petlib it fails with
_DeprecatedInstaller: setuptools.installer and fetch_build_eggs are deprecated.
Requirements should be satisfied by a PEP 517 installer.
If you are using pip, you can try pip install --use-pep517.
OSError: ctypes.util.find_library() did not manage to locate a library called 'crypto'

However, pip install --use-pep517 petlib, also fails!
