Hi, you need a newer setuptools. It's meant to upgrade setuptools when it installs, but I'm guessing it needs a newer setuptools to do that.

[alxnik]

Hello,
I have resolved this issue by removing the "python_version < "3.6"" and reinstalling.

I'm not very keen on upgrading setuptools since it comes as part of the distribution and is supported as part of that. Is there a way to add backwards compatibility to the package itself?

Thanks

[danni]

I don’t recommend installing directly from pip into the OS. Install into a virtualenv. Inside that virtualenv you can then upgrade setuptools safely without affecting the OS. You can also use pip-tools to record the current versions of things, which makes upgrades easier. Also let’s you pin a version of Python. If you look in the tests directory you can see how we combine virtualenv with SCL if that’s what you’re using to get a more recent Python.

Hi @revTimo,

Python 2.7 is not supported. You need at least Python 3.4+. Additionally, it probably doesn't work on Windows yet, as the PKCS#11 lib is loaded via dlopen and there's no Windows mechanism in place.

[revTimo]

thanks for your reply @danni

so do u have any advice for developing with window and Python 2.7

[danni]

The code will never support Python 2.7, it just uses too many Python 3.x features. As for supporting Windows, it's possible, but I haven't tried yet as it hasn't been needed.

[luisza]

Hi, I will need also Windows and MacOS support for my project, so I can help porting to this Operating Systems, but I have planning to work on that in January or February of the next year.

[danni]

macOS should work, I wrote the original code under macOS and have used it to connect to the Nitrokey HSM. It could be added to CI if anyone is aware of a free service (never mind, I've realised I can do it on Travis). Windows doesn't have dlopen so that will need replacing with a call to LoadLibrary.

[revTimo]

hello again @danni

i just upgrade python to version 3.6 and install again pkcs11-tool.
i got a problem in my installing, i dont know what is the error,,
