build fails on OSX 10.10

[gabrielschulhof]

Steps to reproduce:

0. Log into test-macstadium-macos10.10-x64-1
1. git clone https://github.com/nodejs/node
2. cd node
3. ./configure

The result:

From stackoverflow it looks like python may be messed up. I tried to brew reinstall python and brew reinstall python@2 but the former had some kind of link failure and the latter failed entirely.

Looking at the python code it may also be the case that it is not finding the openssl implementation.

Python has been installed as
  /usr/local/bin/python3

Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
  /usr/local/opt/python/libexec/bin

You can install Python packages with
  pip3 install <package>
They will install into the site-package directory
  /usr/local/lib/python3.7/site-packages

brew link --overwrite python worked as suggested by the error message.

[richardlau]

This is most likely the same as nodejs/build#2238 (which I think only fixed the 10.11 macs).

fyi @AshCripps

[srl295]

seeing the same on 12.x on 10.15.4. Trying an xcode upgrade (11.4 to 11.4.1)

update brew uninstall of all pythons python@2 and python@3.8 etc (yes, breaking all the things) and going back to /usr/bin/python worked.

another update
On a lark, I read the manual 🤣 https://docs.brew.sh/Homebrew-and-Python

Homebrew provides formulae to brew Python 3.x.

Homebrew provided a python@2 formula until the end of 2019, at which point it was removed due to the Python 2 deprecation.

So, I did still have python@2. I'm wondering if an 'orphaned' python@2 may be the culprit here as @gabrielschulhof hit. If the formula is gone, then python@2 won't have its deps updated anymore

FormulaUnavailableError: No available formula with the name "/usr/local/opt/python@2/.brew/python@2.rb"

see discussions in nodejs/node-gyp#1337 (comment)

Is there a way Node could detect this situation and suggest something? I'm not sure what the right fix is exactly. Perhaps brew uninstall python@2 --ignore-dependencies and just be aware that any remaining dependencies are probably already broken?

Update I forgot that I was on a 12.x branch, should mention that!

[cclauss]

Is this issue still open?

Python 2 died on 1/1/2020 so brew uninstall python@2 is recommended.

If you have done brew install python and/or brew install python@3.8 then a current version of node-gyp should be working properly. If it is not, then please provide the command that was typed and the complete error log.

[richardlau]

I've been starting several Node.js 10 builds today (I believe we only build Node.js 10 on macOS 10.10 now) and haven't seen the issue reported here.
