Explanation

When facing a missing package version on pipx, specifying the desired version during installation is key to obtaining that specific release. By using == followed by the exact version number, you communicate your preference for that precise release to Python’s packaging tool (pip). This approach ensures that only the specified version is installed, even if newer versions exist. Verifying successful installation confirms that your chosen package and its designated edition are now accessible via pip.
