I want to install version 2.3

Great.
I tried “2.3” :slight_smile:

When you want a specific version is needs to be specified completely, as you just found out :slight_smile:

Can anybody tell me where this syntax is documented?

I (mostly) know how the syntax works, I just don’t know where this is all written down.

Thanks

That page has examples that reference the >= operator, with no explanation of what it does.

It also does not describe how to install an exact version, or what the ~> operator is, or how to use it, or if there are any other operators available.
