How about update pip so that, from the command line it can accept pretty
much the same syntax as the py launcher:
- "python -m pip operation ..." all use the same python as is running
the pip module.
- "pip -X[.Y][-32|-64] operation ..." tries to find a python matching
-X[.Y][-32|-64] and if it succeeds executes "python -m pip operation
..." with that python, (if it doesn't find a matching python is should
fail with a sensible error message and possibly list the valid python
"pip operation ..." searches the available python contexts and, if there
is only one, (or in a venv), calls "python -m pip operation ..." using
it but, if there is more than one candidate, (or in not in a venv),
tells the user that they have more than one python and need to specify
which, listing the options.
"pip -0" searches the available pythons and lists the available contexts.
Ideally the list contexts operations would differentiate between user
space and system contexts and display them suitably based on the current
- maintain the current behaviour as much as possible,
- not break all of the existing examples in the wild & literature
- avoid trying to introduce a new launcher command on Mac/Linux,
- propagate reasonably quickly, as people are already fairly used to
being prompted to update pip,
- Automatically propagate to the default pip as long as it was back
ported to at least 2.7, possibly further.
- Allow users who do need to support multiple python installations to
do so, (I am one of those).
- Does not require updates to python itself.
