Ubuntu 6

When working with Python and its package manager, pipenv, you may encounter a warning message that reads PkgResourcesDeprecationWarning. This warning is related to the versions of Python packages installed on your system and can be triggered when running the command pipenv --version or other related commands. In this article, we will delve into understanding this warning message and how to resolve it.

Quick Answer

The PkgResourcesDeprecationWarning in pipenv --version is a warning message that indicates non-compliant versions of Python packages installed on your system. To resolve this warning, you can downgrade setuptools, upgrade pipenv, upgrade the corresponding packages, or wait for a fix in the Ubuntu package versions.

What is PkgResourcesDeprecationWarning?

The PkgResourcesDeprecationWarning is a warning message indicating that the versions of certain Python packages installed on your system are not compliant with PEP 440. PEP 440 is a specification for versioning in Python packages. This warning is typically triggered when you run the command pipenv --version.

Why Does This Warning Occur?

This warning is usually a result of having non-compliant versions of Python packages installed on your system. These could be packages provided by Ubuntu or other third-party sources. When these packages do not adhere to the versioning standards set by PEP 440, the PkgResourcesDeprecationWarning is triggered.

How to Resolve PkgResourcesDeprecationWarning?

There are several ways to resolve this warning message:

Downgrade setuptools

One possible solution is to downgrade the setuptools package to a version that is compliant with PEP 440. This can be done using the command pip install --upgrade --user setuptools==58.3.0.

Here, pip install is the command to install Python packages. The --upgrade flag is used to upgrade any specified packages to the latest version. The --user flag is used to install packages in the user installation directory. setuptools==58.3.0 specifies that we want to install version 58.3.0 of the setuptools package.

Upgrade pipenv

Another solution is to upgrade pipenv itself. This can be done using the command pip install --upgrade pipenv.

Here, pip install --upgrade pipenv is the command to upgrade pipenv to its latest version.

Upgrade Corresponding Packages

You can run pip list to identify the packages with the corresponding versions causing the errors (e.g., 1.16.0-unknown, 0.1.43ubuntu1, 1.1build1). Then, upgrade those packages to newer versions using the command pip install --upgrade <pkg_name>.

Here, <pkg_name> should be replaced with the name of the package you want to upgrade.

Fix Ubuntu Package Versions

The warnings may be caused by non-compliant versions of Python packages provided by Ubuntu. You can check the bug report linked here for updates on fixing the Ubuntu package versions.
