Create functions to grep through installation logfiles (stdout / stderr) #663

So that we can start to identify some common failure modes.

Eg if there’s a certain installation error we could grep for that and then provide some suggestions on ways to solve it. Eg perhaps a specific version of python needs to be specified

Could work with logfile logger: https://github.com/greta-dev/greta/issues/531

Add an option to trigger a warning if it thinks there is a fatal install error. This can be controlled with a number for sensitivity - e,g, 0 means anything with the word “error” will trigger an error. A 1 means it allows 1 error, etc, with Inf meaning unlimited errors…?

Could build in a similar grepper for warnings as well. The same grepper should be able to have any word searched for, error/Error/ERROR, warning/Warning/warn/Warn/WARN/WARNING/Warns etc

We could also do a better job of identifying errors by grepping through the log files and pulling out relevant parts that might suggest an error
Could pull these out and state that there might have been an error, then pluck those bits out and print them to the user
Can establish a couple of known installation patterns that could work for different users
Eg if there’s a certain installation error we could grep for that and then provide some suggestions on ways to solve it. Eg perhaps a specific version of python needs to be specified
These could be suggested if an install fails

Example error

+ /Users/nick/.virtualenvs/greta-env-tf2/bin/python -m pip install --upgrade --no-user 'tensorflow==2.15.0.*'
ERROR: Could not find a version that satisfies the requirement tensorflow==2.15.0.* (from versions: 2.16.0rc0, 2.16.1, 2.16.2, 2.17.0rc0, 2.17.0rc1, 2.17.0)
ERROR: No matching distribution found for tensorflow==2.15.0.*
Error : Error installing package(s): "'tensorflow==2.15.0.*'"

Which is really weird since I'm fairly sure 2.15.0 exists?

Could not find a version that satisfies the requirement ... means that the python version doesn't match the module python requirements
