These instructions are currently incorrect and need to be ported to
`python` 3.x and `python@2` formulae. Until then it's better to not have
them than have them be incorrect.
Closes#3890.
If an old alias, according to the tab, of a formula being upgraded (e.g.
python) has the same name as the main opt link of some other formula
(e.g. python@2), don't remove the main opt link of that other formula.
Specifically,
brew install python@2
brew upgrade python
should not accidentally delete /usr/local/opt/python@2 even though
python@2 used to be an alias of python.
The current regex only matches a single digit for each component of the version (e.g. 9.2). This modifies it to match multiple digits in each component, so that e.g. 10.42 will be matched.
I believe the Homebrew-and-Python page could use a description on how to exactly install Python 2.X and 3.X with Homebrew.
The syntax is written to my best knowledge (but likely wrong), please update this so that it is correct. Finding out the correct syntax is what actually motivated me to update this page in the first place. I'm hoping that this will clarify to the community (or at least me) on how to exactly install Python 2.X and 3.X with Homebrew.
Keep up the amazing work!
These specify that they are needed by the test block. This can be
combined with `:build` to ensure that this formula isn't uninstalled
by `brew test-bot` when running `test do` blocks on our CI.
I received the following error when attempting to use the `upgrade`
command on a tap:
$ brew tap teddywing/passextract https://github.com/teddywing/Passextract.git
$ brew upgrade --verbose teddywing/passextract/passextract

Or, even better, submit a PR to fix it!
Change the method call to use the (presumably) newer version.
