Incompatible dependencies when installing with pip 10

[jesuxgslp]

Details

Just try a clean local installation following the guide installing-read-the-docs

Expected Result

clean installation

Actual Result

django-haystack 2.8.1 has requirement Django>=1.11, but you'll have django 1.9.13 which is incompatible.

recommonmark 0.4.0 has requirement commonmark<=0.5.4, but you'll have commonmark 0.5.5 which is incompatible.

Please provide your project and build url

Actually is just a fresh readthedocs install (local install) following the oficial guide installing-read-the-docs

[stsewd]

Are you using virtual env or similar?

[jesuxgslp]

Sure, as the guide describe

virtualenv rtd
cd rtd
source bin/activate

[stsewd]

Looks like the latest update of haystack drop support for the Django version that rtd uses django-haystack/django-haystack@514023e#diff-2eeaed663bd0d25b7e608891384b7298L15

[jesuxgslp]

Thanks meanwhile I will try django-haystack==2.7.0

Just keep an eye also in:

recommonmark 0.4.0 has requirement commonmark<=0.5.4, but you'll have commonmark 0.5.5 which is incompatible.

I assume is the same scenario

[stsewd]

@jesuxgslp mmm, yeah, I see. This is weird, recommonmark and commonmark were upgraded a long time ago 64ee6f6 cb219e8

Can you tell me what pip version are you using?

[stsewd]

OK, I just tested it myself, I suspected, this is because pip 10, looks like is more strict about dependencies

[stsewd]

I'm changing the title to be more explicit about the issue.

Hello, are you successful in your local deployment?

I have successfully deployed the local environment here, but I failed to import the project successfully.

Seems like this issue has been resolved!

pip install CommonMark==0.5.4 will solve this problem
