Errors occurred, no packages were upgraded.
later i happend to find that my default version was changed and also was somehow directing to anacondas version.
➜ ~ which pip
/home/arvindh/.miniconda3/bin/pip
➜ ~ which python
python: aliased to /usr/bin/python2.7
➜ ~
i want to change this to the default version. need some help in fixing this up please.
First move from yaourt to pacaur. Pacaur is recommended please take a look at this for more information.
pacaur -S ros-kinetic-ros-core should install all dependencies.
I took a look at the PKGBUILD and it seems like you need Python 2.7 to run it.
I suspect those lines to be responsible for the changes from python3 to python2
# Fix Python2/Python3 conflicts
/usr/share/ros-build-tools/fix-python-scripts.sh -v 2 ${srcdir}/${_dir} with the following into the PKGBUILD
So you should install the python2 pip && setuptools:
pacman -S python2-pip python2-setuptools
