Issue
In virtualenv 20.0.10 at least when a virtualenv environment is created the naming convention of the pip major version file has changed.
In 16.7.x there was pip3.7 in 20.0.2 this has changed to pip-3.7 although there is still pip3 in both, in terms of automation patterns that provision multiple environments and builds there may be many build dependencies that use the pip${MAJOR_VERSION} pattern.
Perhaps adding a symlink to honour the older naming convention may prevent many people spending many hours debugging.
Environment
- OS: CentOS 8
- OS Python: Python 3.6.8
- python interpretor being used for the virtualenv is Python 3.7.6 compiled from source.
- System pip list
pip list --format=columns
