What's the difference between "=" and "==" for conda package versioning?

For example, is there any difference between alembic=1.4.2 and alembic==1.4.2? What about pyyaml=5.4 and pyyaml==5.4?

And if there isn't, what's the preferred way?

Solution

  • From Conda docs:

    The fuzzy constraint numpy=1.11 matches 1.11, 1.11.0, 1.11.1, 1.11.2, 1.11.18, and so on.

    The exact constraint numpy==1.11 matches 1.11, 1.11.0, 1.11.0.0, and so on.
