Pip can't find PyPI package in Artifactory

Question

I build the PyPI package and pushed to our on-prem Artifactory by using jfrog CLI and command:

tar.gz

./jfrog rt upload --url https://artifacts.XYZ.com/artifactory '--props=pypi.name=xyz_easysdlc.traceability_matrix_generator;pypi.version=0.0.1.dev20200102111901+dirty.0.g251f725.mock.develop;pypi.normalized.name=xyz-easysdlc-traceability-matrix-generator' --module=xyz_easysdlc.traceability_matrix_generator --user=**** '--password=****' dist/xyz_easysdlc.traceability_matrix_generator-0.0.1.dev20200102111901+dirty.0.g251f725.mock.develop.tar.gz pypi-main-dev/xyz_easysdlc.traceability_matrix_generator/0.0.1.dev20200102111901+dirty.0.g251f725.mock.develop/

wheel

./jfrog rt upload --url https://artifacts.xyz.com/artifactory '--props=pypi.name=xyz_easysdlc.traceability_matrix_generator;pypi.version=0.0.1.dev20200102111901+dirty.0.g251f725.mock.develop;pypi.normalized.name=xyz-easysdlc-traceability-matrix-generator' --module=xyz_easysdlc.traceability_matrix_generator --user=**** '--password=****' dist/xyz_easysdlc.traceability_matrix_generator-0.0.1.dev20200102111901+dirty.0.g251f725.mock.develop-py3-none-any.whl pypi-main-dev/xyz_easysdlc.traceability_matrix_generator/0.0.1.dev20200102111901+dirty.0.g251f725.mock.develop/

Both are uploaded successfully.

When I'm installing the pip package from .whl file by following steps, it works:

1. Download https://artifacts.xyz.com/artifactory/webapp/#/artifacts/browse/tree/PyPIInfo/pypi-main-dev-local/xyz_easysdlc.traceability_matrix_generator/0.0.1.dev20200102111901+dirty.0.g251f725.mock.develop/xyz_easysdlc.traceability_matrix_generator-0.0.1.dev20200102111901+dirty.0.g251f725.mock.develop-py3-none-any.whl
2. Run pip install ~/Downloads/xyz_easysdlc.traceability_matrix_generator-0.0.1.dev20200102111901+dirty.0.g251f725.mock.develop-py3-none-any.whl

I would then expect, that simply

pip install --pre --index-url https://artifacts.xyz.com/artifactory/api/pypi/pypi-main-dev/simple xyz_easysdlc.traceability_matrix_generator

would work, but I'm getting following error:

ERROR: Could not find a version that satisfies the requirement xyz_easysdlc.traceability_matrix_generator (from versions: none)
ERROR: No matching distribution found for xyz_easysdlc.traceability_matrix_generator

Any guess, guys?

[UPDATE] When I run pip install in verbose mode, I'm getting following output:

But when I navigate to https://artifacts.xyz.com/artifactory/api/pypi/pypi-main-dev/simple/xyz-easysdlc-traceability-matrix-generator/ I can see both, *.whl and *.tar.gz files. Just to make sure, it's not an issue with some "invalid" package name, here are the names of files.

xyz_easysdlc.traceability_matrix_generator-0.0.1.dev20200102111901+dirty.0.g251f725.mock.develop-py3-none-any.whl
xyz_easysdlc.traceability_matrix_generator-0.0.1.dev20200102111901+dirty.0.g251f725.mock.develop.tar.gz

Answer 1

I found the root cause of this issue. Artifactory is sending HTTP Code 404 even in case you are not authorized (v. 6.10.7). When I authenticated for pip install , installation was successful.
