Description

Recently the Travis CI build for 'Compiler: gcc Xcode: xcode7.3 C++' started failing due to the following:

.
.
.
$ export CXX=g++
$ export CC=gcc
$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 7.3.0 (clang-703.0.31)
Target: x86_64-apple-darwin15.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
before_install.1
296.52s$ brew update
66.75s$ brew upgrade python openssl
0.02s$ pip2 install --user --upgrade pip
/Users/travis/.travis/job_stages: line 57: pip2: command not found
The command "pip2 install --user --upgrade pip" failed and exited with 127 during .
Your build has been stopped.

 

This appears to be due to a recent change in homebrew whereby installing 'python' installed python 2 but now installs python 3.

From a previous, working, travis job  

$ brew upgrade python openssl
==> Upgrading 2 outdated packages, with result:
python 2.7.14_2, openssl 1.0.2n

From the latest job that's broken:

$ brew upgrade python openssl
==> Upgrading 2 outdated packages, with result:
python 3.6.4_3, openssl 1.0.2n

Looking on http://formulae.brew.sh/ we see:

🚫 Recently removed formulae
python3, php72-opcache, php72-snmp, php72-tidy, php72
