I am excited about today’s announcement about multi-arch support!!
But I found that pip is not installed in the ppc64le or arm64 images, but is installed in amd64 images.
As a workaround I installed pip like this:
[ $TRAVIS_ARCH = ppc64le ] && sudo apt-get install python-pip python-setuptools
[ $TRAVIS_ARCH = aarch64 ] && sudo apt-get install python-pip python-setuptools
But the version of pip is still not the same as on amd64:
amd64: pip -V -> 19.0.3
arm64, ppc64le: pip -V -> 8.11
