no module named "requests" error about cert-issuer HOT 8 CLOSED

pyld 0.8.1 should fix the requests installation issue.

from cert-issuer.

I am able to repro; it appears to be an issue in pyld with python 3.6. My best guess is that relative imports (which it's using in init.py) is causing problems.

I have a minimal repro with requirements.txt as follows:

pyld>=0.8.0
requests>=2.18.4

Creating a python 3.6 virtualenv causes this to fail with:

Collecting pyld>=0.8.0 (from -r requirements.txt (line 1))
  Using cached PyLD-0.8.0.tar.gz
    Complete output from command python setup.py egg_info:

        import requests
    ModuleNotFoundError: No module named 'requests'

I note that it passes in 2.7 and 3.4 (the other versions I tested).

I'm going to see if there is a way to work around this for python 3.6

from cert-issuer.

here is a minimal repro in travis: https://travis-ci.org/kimdhamilton/pyld-test/jobs/291439728

from cert-issuer.

and actually, I think my note on 2.7 and 3.4 is specific to my environment. It seems to fail in all environments when I run in travis, with this project:

Hi, I've tried some possible ways and finds out that this issue should belongs the library pyld:
https://github.com/digitalbazaar/pyld

I run it's install command pip install PyLD with python 2.7 / python 3+, came out the same error, I'll try another way to do the installation.

Thanks for your help!

I'm unable to find a good consistent workaround for the pyld issue. The relative import appears to be the root cause, so I forked pyld, switched to absolute imports, and published that package as blockcerts-pyld. I've spent a couple of hours on this, so I'm going to quit while I'm ahead and update the blockcerts stack with this. I'll open an issue on pyld in case they can fix this directly, or have a suggested workaround for consumers.
