"ERROR: No matching distribution found" in updating Pipfile.lock in installing a package from private Package Repository of GitLab.com

When we try to install a private package from our Package Repository of GitLab.com, we got the following error. (It worked in v2022.1.18. However, we got this error in v2022.3.23 and v2022.3.24.)

Our package “mypackage20220329” is uploaded at GitLab.com. We prepared the package by following the instruction at https://docs.gitlab.com/ee/user/packages/pypi_repository/ .

Note: We can’t reproduce the error if the package name is “mypypipackage”. It’s because “mypypipackage” is already on pypi. Therefore, we suspect that this error is caused by search at the wrong location in checking the existence of “mypackage20220329”.

• Expected location: https://__token__:{my_secret_token}@gitlab.com/api/v4/projects/{my_project_no}/packages/pypi/simple"
• Current location(Wrong): https://pypi.org/simple

I have narrowed down the bug: It happened sometime after the “2022.1.8” version of Pipenv.

You can get a working, older version of Pipenv like this:

pip install --user pipenv==2022.1.8

@matteius Thanks for the information! As long as it works fine, I think we are OK 😃
