Describe the issue briefly here.

I get

Warning: Your dependencies could not be resolved. You likely have a mismatch in your sub-dependencies.
  First try clearing your dependency cache with $ pipenv lock --clear, then try the original command again.
 Alternatively, you can use $ pipenv install --skip-lock to bypass this mechanism, then run $ pipenv graph to inspect the situation.
  Hint: try $ pipenv lock --pre if it is a pre-release dependency.
Could not find a version that matches requests<3.0,<3.0.0,==2.17.1,>=1.2.3,>=2.0.0,>=2.0.1,>=2.1.0,>=2.10.0,>=2.13.0,>=2.19.1,>=2.3.0,>=2.6.0,~=2.15

Expected result

pip freeze show something..

Actual result

pip freeze is empty

I also tried --skip-lock. But pip freeze was empty

Steps to replicate

sudo pipenv install -r requirements.txt

The version constraints conflict in some of your dependencies or sub-dependencies. Pipenv won't downgrade your top deps automatically. Please find out the conflicting deps and pin the version in Pipfile to make them compatible(It is a long list to go).

Change the title to reflect the real problem.

[cegprakash]

The real problem is that pipenv graph is empty. Why is it empty. If it is not empty, I can play around and try to fix the requirements.txt file. Without that I cannot find the package that's requiring these versions of requests. Please change the title back

[frostming]

Because pipenv will try to lock deps when the virtualenv is first created, and fail there. No dep is installed at all. So pipenv graph is expected to be empty.

You can do pipenv install --skip-lock to bypass the step and you will get output from pipenv graph, but with problematic dep versions installed.

[cegprakash]

I already mentioned that as well.. --skip-lock followed by graph was empty too

[cegprakash]

If you can just identify and tell me out off all these packages what packages need 'requests' as their sub dependency and what version of requests then I will be able to fix my requirements.txt

[frostming]

metadata-parser
newsapi-python

@cegprakash

[cegprakash]

I removed both of them but now I get

Could not find a version that matches numpy<=1.14.5,>=1.12.0,>=1.13,>=1.13.3,>=1.15.0,>=1.7,>=1.7.0,>=1.8.2,>=1.9.0,>=1.9.1,~=1.14

[cegprakash]

I need metadata-parser newsapi-python and numpy

is there anything that I can do?

[cegprakash]

I have managed to make this requirements.txt work but I had to install using --skip-lock. Any way I can utilize the lock?

may be with a pipenv lock --skip-verision-check or something?

[frostming]

No, it just appears to work. Without the resolution process you will be likely get incompatible version of sub-dependency installed. For your case, requests==2.20.1 will be installed while requests==2.17.1 is required for newsapi-python, depending on the installation order, you may get requests==2.17.1 installed then it doesn't fit metadata-parser's constraints. You can do pipenv gragh for a proof.

For the locking to work, you have to pin metadata-parser to a lower version so that it is compatible with requests==2.17.1. By the way, newsapi-python shouldn't have a fixed version of dep. The same goes for other conflicts.

@cegprakash I just updated my comment and I hope it helps.

[cegprakash]

what is the recommended solution to this if I need all these libraries?

it's not just these 3 libraries causing the issues, there are many more

[sdispater]

@cegprakash A minimum set of dependencies in your requirements.txt which will not have any conflict if the following:

Note that there are pinned versions in there that are way outdated but this is due to the fact that there are a lot of conflicts in these packages, so you should revise your dependencies and see if all are needed.

I was able to pull this off by using the Poetry's dependency resolver for information.

Thanks for that, I think we can stop here.
