Hi, I am trying to install ROS on a 64-bit machine running Gentoo linux. When I run the command -

sudo pip install -U rosinstall vcstools

I get the following errors -

Installing collected packages: rosinstall, vcstools, pyyaml

Uninstalling PyYAML:

  Running setup.py install for pyyaml

build/temp.linux-x86_64-3.2/check_libyaml.c:2:18: fatal error: yaml.h: No such file or directory
compilation terminated.

libyaml is not found or a compiler error: forcing --without-libyaml
(if libyaml is installed correctly, you may need to
 specify the option --include-dirs or uncomment and
 modify the parameter include_dirs in setup.cfg)

But then at the bottom it says "Successfully installed rosinstall vcstools pyyaml". So I try to move on to

rosinstall ~/ros "http://packages.ros.org/cgi-bin/gen_rosinstall.py?rosdistro=electric&variant=desktop-full&overlay=no"

but that gives me an error saying there is no module 'headers'. I'm assuming the issue with pip install is the problem. I have gone into the config_elements.py file, removed the ',' causing the syntax error, and tried to pip install again...but it just recreated the file with the syntax error.

I would greatly appreciate it if someone could tell me if they know what is wrong. Thanks.

It seems like Gentoo, similar to Arch, uses python3 per default. I'm not sure if there is a version of pip that uses python2 in Gentoo, but alternatively you should be able to install rosinstall similar to how the Arch rosinstall package does it. Have a look at the tarball linked on this page.

I'm having an issue with this as well. I'm on a mac. It seems it's going to the wrong place to find yaml.h
