Impossible to import OpenSSL module in Python

  • tommaso tani

    Hi everyone,
    I'm kind of going mad on this.
    I have a simple script that imports ssl from OpenSSL module:

    from OpenSSL import ssl

    of course I installed the library via OPKG and made any kind of test and manual install you can imagine but

    ImportError: No module named OpenSSL

    There's no way I can load it. I'm going crazy.
    Thank you guys - I hope I'm missing something really basic. 😄

    @György-Farkas said in Impossible to import OpenSSL module in Python:
    Well, the point is that I'm using the Twisted module and it has

    # System imports
from OpenSSL import SSL                                                        
supported = True

    The module is installed tho:

    root@Omega:~# opkg list-installed | grep python

    Still haven't find a way to fix it, damn.

    Moreover, I run into another funny paradox. I suspect I need to install python-pyopenssl in order to have to right module but opkg is not on my side with this:

    root@Omega:/etc/opkg# opkg list | grep -i python-pyopenssl
python-pyopenssl - 17.2.0-1
root@Omega:/etc/opkg# opkg info python-pyopenssl
Package: python-pyopenssl
Version: 17.2.0-1
Depends: libc, python-light, python-cryptography, python-six
Status: install user not-installed
Architecture: mipsel_24kc

    So, it is listed. Good. an opkg update just to be sure, but then:

    root@Omega:/etc/opkg# opkg install python-pyopenssl
Installing python-pyopenssl (17.2.0-1) to root...
Collected errors:
 * opkg_download_pkg: Package python-pyopenssl is not available from any configured src.
 * opkg_install_pkg: Failed to download python-pyopenssl. Perhaps you need to run 'opkg update'?
 * opkg_install_cmd: Cannot install package python-pyopenssl.

    Sorry, I can't follow you. Unfortunately I don't know the Twisted framework.
    So - most probably - I can't solve your problem. I can only show what is the situation on my Omega2+ (v0.1.10-b160) now.
    Hope this helps (a little ;-).

    I enabled the lede 'packages' repo too - earlier it was disabled.

    So, apparently I solved the issue with the opkg (didn't update, I downloaded the .ipk package from the repo and installed manually).
    I solved the OpenSSL, now I'm struggling with another module (Twisted). LOL

    Thank you so much anyway!
