How to fix How to fix 'Incompatible package versions' error in pip in Python

PythonINTERMEDIATEMEDIUM

The version constraint you specified for a package cannot be satisfied. Either the version doesn't exist, or you've pinned incompatible versions.

What this error means

When you specify a package version that violates its dependencies, pip refuses to install. For example: 'django==2.0' requires 'sqlparse>=0.2.2', but you specified 'sqlparse==0.1'. These versions are incompatible.

Typical symptoms

pip install package==X.Y fails
Error message shows version constraints cannot be met
Installing package with specific version fails
Works with different version of same package
Dependency version mismatch in requirements
Pip shows unsatisfiable version range
Two pinned packages have conflicting dependencies

Common causes

Package version doesn't exist on PyPI
Typo in version number
Version too old or too new for other dependencies
Package was yanked (removed) from PyPI
Python version incompatible with package version
Manually pinned incompatible versions
Misremembering actual version number
