Unexpected Error Resolving Satisfiable Dependencies with Pipenv 11
See original GitHub issueHi All!
When running pipenv lock
on a Pipfile containing pandas==0.18.1
and pandas-datareader==0.5.0
, pipenv
errors out claiming that it can’t find a pandas version satisfying pandas==0.18.1,>=0.19.2
, but pandas-datareader doesn’t require pandas>=0.19.2
until 0.6.0
. In particular, pandas-datareader==0.5.0
has the following requirements:
INSTALL_REQUIRES = (
['pandas>=0.17.0', 'requests>=2.3.0', 'requests-file', 'requests-ftp']
)
I don’t see this behavior in earlier versions of pipenv. With pipenv 10.0, for example, the packages above resolve to the following reasonable-looking versions (hashes omitted for brevity):
"certifi": {
"version": "==2018.1.18"

pandas-datareader = "==0.5"
pandas = "==0.18.1"
Expected result
I expected the Pipfile listed above to resolve to something like the set of dependencies that pipenv 10 finds successfully.
Actual result
pipenv appears to think that pandas-datareader always requires pandas>=0.19, which eventually causes a dependency resolution failure.
(repro) [~/quantopian/repro]$ pipenv lock --clear --verbose
Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project.

I was able to recreate this issue with `pipenv-resolver pandas-datareader==0.5.0 pandas==0.18.1", using:
I believe the source of the dependency conflict is in
pipenv.patched.notpip.index.PackageFinder.find_requirement
, with the value ofignore_compatiblity=True
. (Which was recently changed with this patch, https://github.com/pypa/pipenv/commit/4e906e4bc0df095ed3d61d4d283af02c76ec76d2#diff-6793f5b689d9956dc9b6c175038b718dR491)When
ignore_compatibility
isTrue
, and the spec forpandas-datareader
ispandas-datareader==0.5.0
, the spec is ignored, and all available candidates that are listed on PyPI are considered. Thebest_candidate
value in thefind_requirements
method is then set to0.6.0
, instead of0.5.0
, which adds a constraint ofpandas>=0.19.2
. The correct pandas constraint forpandas-datareader==0.5.0
ispandas>=0.17.0
.Here is a table of the expected constraints for
pandas-datareader
with links to the project’ssetup.py
:0.5.0
>=0.17.0
0.6.0
>=0.19.0
The following patch, which sets the default value of
find_requirements
toFalse
, allows a successful invocation of thepipenv-resolver pandas-datareader==0.5.0 pandas==0.18.1
. (Clearing the depcache before re-running the command is also required.)I am not yet sure if changing that default value will break any other use cases, or cause a regression on https://github.com/pypa/pipenv/issues/1667, the issue which is mentioned in the patch that added the
ignore_compatibility
flag.help me please! I can’t solve this error. ERROR: Could not find a version that satisfies the requirement b1 (from -r requi rements.txt (line 59)) (from versions: none) ERROR: No matching distribution found for b1 (from -r requirements.txt (line 59) )
