The Travis CI builds for macOS X are failing because these now
timeout. This happens because qt is being built from source instead
of being installed from a bottle.
Note that by default the Travis CI will terminate a build after 10
minutes if no output has been received. Unfortunately building qt
from source code may take hours.
To address this issue, choose a macOS X version that has a homebrew
bottle for qt [1].
[1] https://formulae.brew.sh/formula/qt
The homebrew project currently lists having a qt bottle for:
- Mojave (10.14)
- High Sierra (10.13)
- Sierra (10.12)
No bottle is listed for macOS El Capitan (10.11)
In order to support as many versions of macOS X as possible, choose
the lowest osx_image value [2] that is currently supported with a
homebrew bottle.
[2] https://docs.travis-ci.com/user/reference/osx#os-x-version
At this time osx_image value xcode8.3 is listed as supporting OS X
10.12.
The Travis CI builds are failing with the following messages:
sudo -H pip3 install --upgrade pip setuptools wheel
sudo: pip3: command not found
The command "if [ "$TRAVIS_OS_NAME" = "osx" ]; then bash package/prepare_osx.sh; fi" failed and exited with 1 during .
It appears that homebrew recipes for Python3 and pip3 install and
invocation keep changing (see Homebrew version after 1.5).

The Travis CI build reports the following in the messages from
executing package/prepare_osx.sh:
sudo pip3 install --upgrade pip setuptools wheel
The directory '/Users/travis/Library/Caches/pip/http' or its \
parent directory is not owned by the current user and the cache \
has been disabled. Please check the permissions and owner of that \
directory. If executing pip with sudo, you may want sudo's -H \
flag.
The directory '/Users/travis/Library/Caches/pip' or its parent \
directory is not owned by the current user and caching wheels has \
been disabled. check the permissions and owner of that \
directory. If executing pip with sudo, you may want sudo's -H \
flag.
In an effort to address this issue, add "-H" flag to sudo.
The Travis CI builds have been failing with the following message:
The command "if [ "$TRAVIS_OS_NAME" = "osx" ]; then \
bash package/prepare_osx.sh; fi" \
failed and exited with 1 during .
This above line of code is from .travis.yml. Further examination of
the log from executing package/prepare_osx.sh shows the following
message:
<snip>
brew install python3 enchant
Error: python 2.7.12_1 is already installed
To upgrade to 3.6.5, run `brew upgrade python`
<snip>
Based on this message it appears that the method to install python3
has changed. Hence change command to upgrade python 2.x to 3.x.
